This page details the Player settings specific to iOS. For a description of general Player settings that apply to all platforms, see Player - General settings.

Standalone iOS Player settings
Standalone iOS Player settings

You can find documentation for the properties in the following sections:


Use the Icon settings to customize the branding for your app on the Apple Store.

Icon settings in the iOS Player settings
Icon settings in the iOS Player settings

You can upload and assign these types of custom icons for each iOS device (iPhone, iPad):

Icon type Where it displays
Application icons Main icons for your app
Spotlight icons Spotlight search results for your app
Settings icons Device’s main Settings page
Notification icons Notifications sent from your app
Marketing icons App Store

All icons you upload are Texture 2D-type Assets. If an icon Texture is missing, Unity scales the icon Texture with the nearest size, with a preference towards using larger Textures.

Resolution and presentation

Use the Resolution and Presentation section to customize aspects of the screen’s appearance.

These settings are split into the following categories:

Resolution Scaling player settings for the iOS platform
Resolution Scaling player settings for the iOS platform

Resolution Scaling

Use the Resolution Scaling Mode setting to set the scaling to be equal to or below the native screen resolution:

Setting Function
Disabled Scaling doesn’t apply and the application renders to its native screen resolution.
FixedDPI When you select this value, the Target DPI property appears.

Use the Target DPI property to set the target DPI of the game screen. Unity downscales the game screen to match this setting if the device’s native screen DPI is higher than this value. This helps you optimize performance and battery life. You can also use it to target a specific DPI setting.

Unity calculates the scale as min(Target DPI * Factor / Screen DPI, 1). The Factor uses the Resolution Scaling Fixed DPI Factor value you enter in the Quality settings.
Reset resolution on window resize Indicates whether to set the screen resolution to the new native window size when the native window size changes. If you set Resolution Scaling Mode to Fixed DPI, Unity recalculates the resolution based on Fixed DPI property.


Choose the game’s screen orientation from the Default Orientation drop-down menu. The default setting is Auto Rotation. If selected, this setting causes the screen to rotate with device orientation.

Select a different setting to determine a fixed location for where the Home button appears on the screen:

Setting Home button position
Portrait Bottom
Portrait Upside Down Top
Landscape Left Right side
Landscape Right Left side.
Auto Rotation Screen orientation changes with device orientation. This is the default.

Note: The Default Orientation setting applies to both iOS and Android devices.

When you select Auto Rotation as the Default Orientation, these settings appear:

Setting Function
Use Animated Autorotation If you enable this check box, when the user rotates the device, screen rotation uses an animated transition. Otherwise, screen rotation changes instantly.
Allowed Orientations for Auto Rotation Auto Rotation changes screen orientation to match the device. You might want to limit the screen orientations allowed (for example, locking a device to landscape). Enable each orientation you want to allow by checking its box in this section.

Multitasking Support

Enable the Requires Fullscreen option if your application needs to run in full screen mode.

Status Bar

Use the Status Bar section to specify parameters related to the iOS status bar.

Setting Function
Status Bar Hidden Enable this option to hide the status bar when your application launches.
Status Bar Style Define the style of the status bar when the application launches. The options are Default and Light.
Disable Depth and Stencil Enable this option to disable the depth and stencil buffers.
Render Over Native UI Enable this option to force your app to render on top of the native iOS UI.
Show Loading Indicator Select how the loading indicator appears. The options are White Large, White, and Gray.

Splash image

Use the Splash Image section to customize your app’s splash image for different iOS-supported devices.

Splash Settings for the iOS platform
Splash Settings for the iOS platform

The Virtual Reality Splash Image setting, located above the common Splash Screen settings, allows you to select a custom splash image for Virtual Reality displays.

Custom storyboards

Using a Storyboard as a launch screen for iOS
Using a Storyboard as a launch screen for iOS

When you select the Custom Storyboard option in the Launch screen type dropdown for either iPhone or iPad, the Custom Storyboard button appears.

Click the Custom Storyboard button to select a storyboard to show when your game starts up on the device. For your storyboard to appear here, you must first create the storyboard in Xcode and copy it to your Project. For more information, see Apple developer documentation about storyboards, scenes, and connections.

When you disable the Use Storyboard for Launch Screen checkbox, you can implement splash images with one of these methods:

If you don’t use custom storyboards, you can use Unity’s built-in launch screens to implement splash images.

Launch Screens

A launch screen is a Storyboard file from which iOS creates a splash screen on the device. It has the following limitations:

  • You can’t display different content based on device orientation for iPads.
  • All iPhones support landscape launch screens, but certain iOS versions show the Landscape Left launch screen instead of the Landscape Right one due to a bug.
  • Before iOS 13, it was impossible to override the root view controller for a storyboard, so the launch screen supports all orientations and ignores some UI(User Interface) Allows a user to interact with your application. Unity currently supports three UI systems. More info
    See in Glossary
    settings, like status bar behavior. Starting with iOS 13, launch screen is fully compliant with your app’s settings for orientation and status bar appearance.

These limitations also apply to custom storyboards.

Select the Launch screen type for iPhone and iPad in the the iPhone Launch Screen and iPad Launch Screen sections:

Value Function
Default When you select this option, Unity adds a solid blue-black image that’s the same color as the background for Unity’s default splash screen. The image is used for both portrait and landscape orientations, and displays using aspect-fill mode.
None Apple no longer supports Launch Images. This option exists for backwards compatibility reasons. If you select it, your project will use Unity’s default splash screen instead.
Image and background (relative size) Displays an image in the center of the screen and fills the remaining area with a solid color.
Portrait Image Select an image for portrait orientation.
Landscape Image Select an image for landscape orientation.
Background Color Select a background color to fill any screen space that the image doesn’t cover.
Fill percentage Specify image size as a percentage of the screen size. Unity calculates image size based on the length or width of the screen, whichever one is smaller (vertical for landscape displays, horizontal for portrait ones).
Image and background (constant size) Displays an image in the center of the screen and fills the area with a solid color. This has the same options as Image and background (relative size), except that you specify image size in points rather than as a percentage.

Tip: Points and pixels are not the same. A pixel (px) is a single dot in your image. A point (pt) is a unit of length that measures 1/72th of an inch. Pixel sizes are relative to the screen size and resolution, while point sizes are the size on any screen. For more information, see W3C guidance on size units.
Custom XIB When you select this option, the Custom XIB button appears. Click the button to select a custom XIB file to use as a loading screen.
Custom Storyboard When you select this option, the Custom Storyboard button appears. Click the button to select a custom Storyboard file to use as a loading screen.

Note: With a Unity Personal subscription, the Unity Splash Screen displays as soon as the engine initializes, in addition to your chosen splash screen.

Debugging and crash reporting

Use the Debugging and crash reporting settings to gather data about your app’s performance and troubleshoot crashes.

Debugging and crash reporting on the iOS platform
Debugging and crash reporting on the iOS platform
Setting Function
Enable Internal Profiler (Deprecated) This feature is deprecated and will be retired in a future version of Unity. Use the Profiler window instead (menu: Window > Analytics > Profiler).

The Profiler collects application performance data and prints a report to the console. The report contains the number of milliseconds each Unity subsystem takes to execute on each frame, averaged across 30 frames.
On .Net UnhandledException Select the action Unity takes when a .NET unhandled exception occurs. The options are Crash (the app crashes and generates a crash report, which users can submit to iTunes and developers can use to troubleshoot the crash), or Silent Exit (the application exits with no errors and doesn’t generate a crash report).
Log Obj-C Uncaught Exceptions When you enable this action, Unity prints Objective-C Uncaught Exception information to the console.
Enable Crash Report API Enables a custom crash reporter to capture crashes. You can use scripts to access crash logs via the CrashReport API.

Other settings

You can configure a range of Player settingsSettings that let you set various player-specific options for the final game built by Unity. More info
See in Glossary
in the Other Settings section. These options are organized into the following groups:


Use these settings to customize how Unity renders your application for the iOS platform.

Rendering Player settings for iOS platforms
Rendering Player settings for iOS platforms
Setting Function
Color Space Choose which color space Unity uses for rendering: Gamma or Linear. See the Linear rendering overview for an explanation of the difference between the two.
Gamma: Gamma color space is typically used for calculating lighting on older hardware restricted to 8 bits per channel for the framebuffer format. Even though monitors today are digital, they might still take a gamma-encoded signal as input.
Linear: Linear color space rendering gives more precise results. When you select to work in linear color space, the Editor defaults to using sRGB sampling. If your Textures are in linear color space, you need to work in linear color space and disable sRGB sampling for each Texture.
Color Gamut You can add or remove color gamuts for the iOS platform to use for rendering. Click the plus (+) icon to see a list of available gamuts. A color gamut defines a possible range of colors available for a given device (such as a monitor or screen). The sRGB gamut is the default (and required) gamut.
When targeting recent tvOS devices with wide color gamut displays, use DisplayP3 to use the full display capabilities. Use Metal Editor Support as a fallback for older devices.
Multithreaded Rendering Enable this option to move graphics API calls from Unity’s main thread to a separate worker thread. This can help to improve performance in applications that have high CPU usage on the main thread.
Static BatchingA technique Unity uses to draw GameObjects on the screen that combines static (non-moving) GameObjects into big Meshes, and renders them in a faster way. More info
See in Glossary
Enable this option to use static batching. For more information, see Draw call batching.
Dynamic BatchingAn automatic Unity process which attempts to render multiple meshes as if they were a single mesh for optimized graphics performance. The technique transforms all of the GameObject vertices on the CPU and groups many similar vertices together. More info
See in Glossary
Enable this option to use dynamic batching (enabled by default). For more information, see Draw call batching.

Note: Dynamic batching has no effect when a Scriptable Render Pipeline is active, so this setting is only visible if the Scriptable Render Pipeline Asset Graphics setting is blank.
Compute Skinning Enable this option to use Metal GPU compute skinning, which frees up CPU resources. To learn more about GPU compute skinning, see the Wikipedia page on skeletal animation.
Graphics Jobs (Experimental) Enable this option to instruct Unity to offload graphics tasks (render loops) to worker threads running on other CPU cores. This reduces the time spent in Camera.Render on the main thread, which is often a bottleneck.

Note: This feature is experimental. It might not deliver a performance improvement for your Project, and might introduce instability.
Texture compression format Choose between ASTC and PVRTC as the default texture compression format for iOS. Check the texture compression format overview for more information.
Normal Map Encoding Choose XYZ or DXT5nm-style to set the normal map encoding. This affects the encoding scheme and compression format used for normal maps. DXT5nm-style normal maps are of higher quality, but more expensive to decode in shaders.
Lightmap Encoding Choose Low Quality, Normal Quality, or High Quality to set the lightmap encoding. This setting affects the encoding scheme and compression format of the lightmaps.
HDR Cubemap Encoding Choose Low Quality, Normal Quality, or High Quality to set the HDR Cubemap encoding. This setting affects the encoding scheme and compression format of the HDR Cubemaps.
Lightmap Streaming Whether to use Mipmap Streaming for lightmaps. Unity applies this setting to all lightmaps when it generates them.
Note: To use this setting, you must enable the Texture Streaming Quality setting.
  Streaming Priority Set the priority for all lightmaps in the Mipmap Streaming system. Unity applies this setting to all lightmaps when it generates them.
Positive numbers give higher priority. Valid values range from –128 to 127.
Frame Timing Stats Enable this property to gather CPU and GPU frame time statistics. Use this together with the Dynamic ResolutionA Camera setting that allows you to dynamically scale individual render targets, to reduce workload on the GPU. More info
See in Glossary
camera setting to determine if your application is CPU or GPU bound.
Virtual Texturing Currently not supported on iOS.
Shader precision model Controls the default precision of samplers used in shaders. See Shader data types and precision for more details.
360 Stereo Capture Currently not supported on iOS.
Auto Graphics API Disable this option to manually set the graphics APIs. This option is enabled by default, and includes Metal.
Metal Editor Support Enable this option to use the Metal API in the Unity Editor and unlock faster Shader iteration for targeting the Metal API.

Note: Checking or unchecking this option requires you to restart the Editor before the changes take effect.
Metal API Validation Enable this option when you need to debug Shader issues. This option displays if the Metal Editor Support checkbox is active.

Note: Validation increases CPU usage, so use it solely for debugging.
Metal Write-Only Backbuffer Allow improved performance in non-default device orientation. This sets the frameBufferOnly flag on the back buffer, which prevents readback from the back buffer but enables some driver optimization.
Force hard shadows on Metal Enable this option to force Unity to use point sampling for shadows on Metal. This reduces shadow quality, which improves performance.
Memoryless Depth Choose when to use memoryless render textures. Memoryless Render Textures are temporarily stored in the on-tile memory when rendered, not in CPU or GPU memory. This reduces your app’s memory usage of your app, but you cannot read or write to these Render Textures.

Note: Memoryless Render Textures are only supported on iOS, tvOS 10.0+ Metal and Vulkan. On other platforms, Render Textures are read/write protected and stored in CPU or GPU memory.
Unused Never use memoryless framebuffer depth.
Forced Always use memoryless framebuffer depth.
Automatic Let Unity decide when to use memoryless framebuffer depth.


Enter identifying information for your app.

Identification settings for iOS platforms
Identification settings for iOS platforms
Setting Function
Override Default Bundle Identifier Indicates whether you can manually set the bundle identifier.
Note: This setting affects macOS, iOS, tvOS, and Android.
Bundle Identifier Enter the provisioning profile of the application you are building. The basic structure of the identifier is com.CompanyName.ProductName. This structure might vary based on which country you live in, so always default to the string Apple provides to you for your Developer Account. Your ProductName is set up in your provisioning certificates.
The Bundle Identifier must follow the convention com.YourCompanyName.YourProductName and must contain only alphanumeric and hyphen characters. For more information, see CFBundleIdentifier.
Important: Unity automatically replaces any invalid characters you type with a hyphen.

To set this property, enable Override Default Bundle Identifier.
Version Enter the release-version-number string for the bundle (for example, 4.3.6).

This value appears as CFBundleShortVersionString in the associated info.plist file. For more information, see Apple developer documentation on CFBundleShortVersionString.
BuildThe process of compiling your project into a format that is ready to run on a specific platform or platforms. More info
See in Glossary
Enter the build number for this version of your app.

This value appears as CFBundleVersion in the associated info.plist file. For more information, see Apple developer documentation on CFBundleVersion.
Signing Team ID Enter your Apple Developer Team ID. You can find this on the Apple Developer website under Xcode Help. This sets the Team ID for the generated Xcode project, allowing developers to use Build and Run functionality. You must enter an Apple Developer Team ID for automatic signing of your app.

For more information, see the Apple developer documentation on Creating Your Team Provisioning Profile.
Automatically Sign Enable this option to instruct Xcode to automatically sign your build.


Configuration settings for iOS platforms
Configuration settings for iOS platforms

API configuration settings

Setting Function
Scripting BackendA framework that powers scripting in Unity. Unity supports three different scripting backends depending on target platform: Mono, .NET and IL2CPP. Universal Windows Platform, however, supports only two: .NET and IL2CPP. More info
See in Glossary
The scripting backend determines how Unity compiles and executes C# code in your Project. This setting defaults to IL2CPP for iOS and can’t be changed.

IL2CPP compiles C# code into CIL, converts the CIL to C++, and then compiles that C++ into native machine code, which executes directly at run time. For more information, see documentation on IL2CPPA Unity-developed scripting back-end which you can use as an alternative to Mono when building projects for some platforms. More info
See in Glossary

C++ code generated by the IL2CPP scripting backend can be updated incrementally, which allows incremental C++ build systems to compile only the changed source files. This can significantly lower iteration times.
API Compatibility Level Choose which .NET APIs you can use in your project. This setting can affect compatibility with 3rd-party libraries. However, it has no effect on Editor-specific code (code in an Editor directory, or within an Editor-specific Assembly Definition).
.Net Standard 2.0 Compatible with .NET Standard 2.0. Produces smaller builds and has full cross-platform support.
.Net 4.x Compatible with the .NET Framework 4 (which includes everything in the .NET Standard 2.0 profile as well as additional APIs). Choose this option when using libraries that access APIs not included in .NET Standard 2.0. Produces larger builds and any additional APIs available are not necessarily supported on all platforms. See Referencing additional class library assemblies for more information.
C++ Compiler Configuration The C++ compiler configuration used when compiling IL2CPP generated code. This setting defaults to Release for iOS and can’t be changed.
Use incremental GC Use the incremental garbage collector, which spreads garbage collection over several frames to reduce garbage collection-related spikes in frame duration. For more information, see documentation on Automatic Memory Management.

API Compatibility Level

You can choose your mono API compatibility level for all targets. Sometimes a third-party .NET library uses functionality that is outside of your .NET compatibility level. If you’re on Windows, you can use the third-party software ILSpy to understand what’s happening and how to fix it. Follow these steps:

  1. Install ILSpy for Windows.
  2. Drag the .NET assemblies for the API compatibility level that you are having issues with into ILSpy. You can find these under Frameworks/Mono/lib/mono/YOURSUBSET/.
  3. Drag in your third-party assembly.
  4. Right-click your third-party assembly and select Analyze.
  5. In the analysis report, inspect the Depends on section. Anything that the third-party assembly depends on, but that’s not available in the .NET compatibility level of your choice, is highlighted in red.

Optimization settings for iOS platforms
Optimization settings for iOS platforms
Setting Function
Prebake Collision Meshes Enable this option to add collision data to Meshes at build time.
Keep Loaded Shaders Alive When enabled, you cannot unload a shader. See Shader Loading for more information.
Preloaded Assets Set an array of Assets for the player to load on startup.
To add new Assets, increase the value of the Size property, then set a reference to the Asset to load in the new Element box that appears.
Strip Engine Code Enable this option if you want the Unity Linker tool to remove code for Unity Engine features that your Project doesn’t use. This setting is only available with the IL2CPP scripting backend.

Most apps don’t use every available DLL. This option strips out DLLs that your app doesn’t use to reduce the size of the built Player. If your app is using one or more classes that would normally be stripped out under your current settings, Unity displays a debug message when you try to build the app.
Managed Stripping Level Choose how Unity strips unused managed (C#) code.The options are Disabled Low, Medium, and High.

When Unity builds your app, the Unity Linker process can strip unused code from the managed DLLs your Project uses. Stripping code can make the resulting executable significantly smaller, but can sometimes accidentally remove code that is in use. For more information about these options, see documentation on Managed code stripping.

For information about bytecode stripping with IL2CPP, see documentation on Managed bytecode stripping with IL2CPP.
Script Call Optimization Choose how to optionally disable exception handling for a speed boost at run time. For more information, see iOS Optimization.
Slow and Safe Use full exception handling (with some performance impact on the device when using the Mono scripting backend).
Fast but no Exceptions No data provided for exceptions on the device (the app runs faster when using the Mono scripting backend).
Note: Using this option with the IL2CPP scripting backend doesn’t impact performance, but it might help avoid undefined behavior on release builds.
Vertex Compression Choose the channel that you want to set for compressing meshes under the vertex compression method, which by default, is set to Mixed. This affects all the meshes in your project. Typically, Vertex Compression is used to reduce the size of mesh data in memory, reduce file size, and improve GPU performance. For information on how to configure vertex compression and limitations of this setting, see [compressing meshes].
Optimize Mesh Data Selecting this option enables stripping of unused vertex attributes from the mesh used in a build.
This reduces the amount of data in the mesh, which might help reduce build size, loading times, and runtime memory usage. However, you must remember to not change material or shader settings at runtime, if you have this setting enabled. See PlayerSettings.stripUnusedMeshComponents for more information.
