    Is the iOS 11 SDK usable with the current Unity Build in 5.5.4p5 ? I tried an empty project with a spinning cube and xcode still spits out the following errors:

    UnityMetalSupport.h:20:20: error: typedef redefinition with different types ('NSUInteger' (aka 'unsigned long') vs 'enum MTLPixelFormat')
    UnityMetalSupport.h:23:5: error: redefinition of enumerator 'MTLPixelFormatBGRA8Unorm'
    MTLPixelFormatBGRA8Unorm,
    ^

    I already excluded Metal from the allowed Graphics APIs in the Player Settings.

    These kind of errors I only see when I try to build for Simulator. There's no need to exclude Metal from Graphics API.
    In my case helped commeting line 20-25 in UnityMetalSupport.h
    It was only way for me to build for simulator without any errors.
    However remember to uncomment these when you build for Device SDK!

    Thanks mobadu

    I added #if !TARGET_OS_SIMULATOR at the line.

    Wow, thanks mobadu and zorgem80! This problem was killing me - costing precious time until I found your answer!
    Hopefully Unity fixes it soon.

    Unity 5.6.1f1 Xcode 9.2
