iOS Player settings - 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:

• RenderingThe process of drawing graphics to the screen (or to a render texture). By default, the main camera in Unity renders its view to the screen. More info
  See in Glossary
• Identification
• Configuration
• Optimization
• Logging
• Legacy

Rendering

Use these settings to customize how Unity renders your application for the iOSApple’s mobile operating system. More info
See in Glossary platform.

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.
Auto Graphics API		Disable this option to manually set the graphics APIs. This option is enabled by default, and includes Metal
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 iOS devices with wide color gamut displays, use DisplayP3 to utilize full display capabilities. Use Metal Editor Support as a fallback for older devices.
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 only displays if the Metal Editor Support checkbox is selected. Note: Validation increases CPU usage, so use it only 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.
Multithreaded Rendering		Enable this option to use multithreaded rendering.
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 skinningThe process of binding bone joints to the vertices of a character’s mesh or ‘skin’. Performed with an external tool, such as Blender or Autodesk Maya. More info See in Glossary, 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. Unity currently only supports Graphics Jobs when using Vulkan and this setting has no effect when using OpenGL ES.
Normal Map Encoding		Choose XYZ or DXT5nm-style to set the normal map encoding. This setting affects the encoding scheme and compressionA method of storing data that reduces the amount of storage space it requires. See Texture Compression, Animation Compression, Audio Compression, Build Compression. See in Glossary format used for normal mapsA type of Bump Map texture that allows you to add surface detail such as bumps, grooves, and scratches to a model which catch the light as if they are represented by real geometry. More info See in Glossary. DXT5nm-style normal maps are of higher quality, but more expensive to decode in shadersA small script that contains the mathematical calculations and algorithms for calculating the Color of each pixel rendered, based on the lighting input and the Material configuration. More info See in Glossary.
Lightmap Encoding		Choose Low Quality, Normal Quality, or High Quality to set the lightmapA pre-rendered texture that contains the effects of light sources on static objects in the scene. Lightmaps are overlaid on top of scene geometry to create the effect of lighting. More info See in Glossary encoding. This setting affects the encoding scheme and compression format of the lightmaps.
Lightmap Streaming Enabled		Enable this option to load only the lightmap mipmaps as needed to render the current Cameras. This value applies to the lightmap textures as they are generated. Note: To use this setting, you must enable the Texture Streaming Quality setting.
Streaming Priority		This option only displays when lightmap streaming is enabled. Set the lightmap mipmap streaming priority to resolve resource conflicts. As these values generate, Unity applies them to the light map textures. Positive numbers give higher priority. Valid values range from –128 to 127.
Enable Frame Timing Stats		Enable this option to gather CPU/GPU frame timing statistics.

Identification

Enter identifying information for your app.

Setting	Function
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. This value appears as CFBundleIdentifier in the associated info.plist file. For more information, see the Apple developer documentation on CFBundleIdentifier. Note: This setting affects iOS, tvOS, and Android.
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.

• C: Device information
• D: Variant map for app slicing
• E: Other configuration settings

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		The compatibility level determines which .NET APIs you can use in your Project. This setting can affect compatibility with third-party libraries. Tip: If you’re having problems with a third-party assembly, you can try the suggestions in the API Compatibility Level section below.
	.Net Standard 2.0	Compatible with .NET Standard 2.0. Produces smaller builds and has full cross-platform support.
	.Net 4.x	Choose this option when using libraries that access APIs not included in .NET Standard 2.0. Compatible with the .NET Framework 4 (which includes everything in the .NET Standard 2.0 profile as well as additional APIs). Produces larger builds and some of the additional APIs available might not be supported on all platforms. For more information, see documentation on Referencing additional class library assemblies.
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 Reflector to understand what’s happening and how to fix it. Follow these steps:

1. Install Reflector for Windows.
2. Drag the .NET assemblies for the API compatibility level you are having issues with into Reflector. 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 is not available in the .NET compatibility level of your choice, is highlighted in red.

Apple-specific information

Setting	Function
Camera Usage Description	Enter the reason for accessing the cameraA component which creates an image of a particular viewpoint in your scene. The output is either drawn to the screen or captured as a texture. More info See in Glossary on the iOS device.
Location Usage Description	Enter the reason for accessing the location of the iOS device.
Microphone Usage Description	Enter the reason for accessing the microphone on the iOS device.
Use on Demand Resource	Enable this option to use on-demand resources. When enabled, the Variant map for app slicing section appears.
Accelerometer Frequency	Define how often to sample the accelerometer. You can set the frequency at 15Hz, 30Hz, 60Hz, or 100Hz. Alternatively, select Disbaled to ignore the accelerometer.
Mute Other Audio Sources	Enable this option if you want your app to stop audio from other apps that run in the background. Otherise, background audio continues to play alongside your app.
Prepare iOS for Recording	Enable this option to initialize the microphone recording APIs. This lowers recording latency, but it also re-routes iPhone audio output via earphones.
Force iOS Speakers when Recording	Enable this option to send the phone’s audio output through the internal speakers, even when headphones are plugged in and recording.
Requires Persistent WiFi	Enable this option to require a Wi-Fi connection. iOS maintains the active Wi-Fi connection while the app is running.
Allow downloads over HTTP (nonsecure)	Enable this option to allow downloading content over HTTP. The default and recommended file transfer protocol protocol is HTTPS, which is more secure.

	Universal	Support all architectures. This is the recommended option.
	Armv7	Support only the older 32-bit ARM architecture.
	Arm64	Support only the newer 64-bit ARM architecture. You might want to consider selecting this option if your app is only for high-end devices.
Active Input Handling		Choose how you want to handle input from users.
	Input Manager (Old)	Use the traditional Input settings.
	Input System (New)	Use the new Input system. The Input System is provided as a preview packageA preview package is in development and not yet ready for production. A package in preview might be at any stage of development, from the initial stages to near completion. See in Glossary for this release. To try a preview of the Input System, install the InputSystem package.
	Both	Use both systems side by side.

Script Compilation

Setting		Function
Scripting Define Symbols		Set custom compilation flags. For more details, see the documentation on Platform dependent compilation.
Additional Compiler Arguments		Add entries to this list to pass additional arguments to the Roslyn compiler. Use one new entry for each additional argument. To create a new entry, press the ‘+’ button. To remove an entry, press the ‘-’ button. When you have added all desired arguments, click the Apply button to include your additional arguments in future compilations.The Revert button resets this list to the most recent applied state.
Suppress Common Warnings		Disable this setting to display the C# warnings CS0169 and CS0649.
Allow ‘unsafe’ Code		Enable support for compiling ‘unsafe’ C# code in a pre-defined assembly (for example, Assembly-CSharp.dll). For Assembly Definition Files (.asmdef), click on one of your .asmdef files and enable the option in the Inspector window that appears.
Use Deterministic Compilation		Disable this setting to prevent compilation with the -deterministic C# flag. With this setting enabled, compiled assemblies are byte-for-byte identical each time they are compiled. For more information, see Microsoft’s deterministic compiler option documentation.
Enable Roslyn Analyzers		Disable this setting to compile user-written scriptsA piece of code that allows you to create your own Components, trigger game events, modify Component properties over time and respond to user input in any way you like. More info See in Glossary without Roslyn analyzer DLLs that might be present in your project.
Use Roslyn Reference Assemblies		Disable this setting to the compiler not to skip compilation reference assemblies when the metadata of the assembly does not change.

Optimization

Setting		Function
Prebake CollisionA collision occurs when the physics engine detects that the colliders of two GameObjects make contact or overlap, when at least one has a Rigidbody component and is in motion. More info See in Glossary Meshes		Enable this option to add collision data to Meshes at build time.
Keep Loaded Shaders Alive		Enable this option to prevent shaders from being unloaded.
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.
AOT compilation options		Additional options for Ahead of Time (AOT) compilation. This helps optimize the size of the built iOS player.
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 aggressively Unity strips unused managed (C#) code. 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. This setting allows you to choose how aggressively Unity should remove unused code. The options available are Disabled, Low, Medium, and High. 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		Set vertex compression per channel. For example, you can enable compression for everything except positions and lightmap UVs. Global MeshThe main graphics primitive of Unity. Meshes make up a large part of your 3D worlds. Unity supports triangulated or Quadrangulated polygon meshes. Nurbs, Nurms, Subdiv surfaces must be converted to polygons. More info See in Glossary compression settings for an imported Object override these settings.
Optimize Mesh Data		Enable this option to remove any data from Meshes that isn’t required by the Material applied to them (such as tangents, normals, colors, and UVs).

Logging

Select what type of logging to allow in specific contexts.

Check one box that corresponds to each Log Type (Error, Assert, Warning, Log, and Exception) when running scripts (ScriptOnly) , all the time (Full), or never (None).

Legacy

Enable the Clamp BlendShapes (Deprecated) option to clamp the range of Blend Shape weights in SkinnedMeshRenderers. This option has been deprecated and should no longer be used.
