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.
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 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 and quality for iOS compared with MP3 playback.
Unity iOS does not support DXT textures. Instead, ASTC, PVRTC, ETC2, and ETC texture compression3D Graphics hardware requires Textures to be compressed in specialized formats which are optimized for fast Texture sampling. More info
