Learn about the system requirements and compatibility information for iOS to make sure you’re aware of any limitations for developing a Unity application for this platform.
Unity supports iOS 13 and above. For more information, see PlayerSettings.iOS-targetOSVersionString.
When developing for iOS, it’s recommended to use Xcode version 15+. For more information, refer to Xcode.
iOS devices support Metal. For more information, see Metal Graphics API.
Unity supports importing a variety of source format sound files. However, when importing these files (with the exception of tracker files), they are always re-encoded to the build target format. By default, this format is Vorbis, though this can be overridden per platform to other formats (ADPCM, MP3, etc.) if required. Vorbis playback provides better compression and quality for iOS compared with MP3 playback.
Unity iOS doesn’t support DXT textures. Instead, ASTC, PVRTC, ETC2, and ETC texture compression are natively supported by iPhone and iPad devices. For more information about iOS texture formats, refer to Texture Import Settings window reference and Choose a GPU texture format by platform.
iPadOS supports multitasking modes that allow users to run applications in split-screen or windowed layouts. The available modes vary by iPadOS version: Split View and Slide Over (iPadOS 9 to iPadOS 18), Stage Manager (iPadOS 16 and later), and Windowed Apps (iPadOS 26 and later). Unity applications support all multitasking modes and respond correctly when the available space changes. For more information, refer to iPad multitasking modes.
