Create iOS Build for iOS 11 with Unity 5.5.4p5

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.

 

Are you trying to build simulation build ? I am trying to build a simulation build and getting same error as above :/ . My unity version is : 5.6.1f1 , Xcode : 9 ..

 

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

 

can you help me? I don't understand what I have to do here.
