It's a bug.

It's fixed in Xcode 8.1 beta.

Xcode 8.1 beta [AVAssetExportSession allExportPresets] iPhone 7 Simulator now returns

AVAssetExportPreset1920x1080,
AVAssetExportPresetLowQuality,
AVAssetExportPresetAppleM4A,
AVAssetExportPreset640x480,
AVAssetExportPreset3840x2160,
AVAssetExportPresetHighestQuality,
AVAssetExportPreset1280x720,
AVAssetExportPresetMediumQuality,
AVAssetExportPreset960x540

Xcode 8.0 [AVAssetExportSession allExportPresets] iPhone 7 Simulator returns an empty array
