How to clear architecture warnings in Xcode 11

[mikemee]

After adding this (fantastic!) project to mine in Xcode 11, I received 3 compile warnings like this:

• Warning: Mapping architecture arm64 to x86_64. Ensure that this target's Architectures and Valid Architectures build settings are configured correctly for the iOS Simulator platform.
• Warning: Mapping architecture armv7 to i386. Ensure that this target's Architectures and Valid Architectures build settings are configured correctly for the iOS Simulator platform.
• Warning: Mapping architecture armv7s to i386. Ensure that this target's Architectures and Valid Architectures build settings are configured correctly for the iOS Simulator platform.

I was able to silence these after reading this Stack Overflow answer https://stackoverflow.com/a/52392083/19506 by changing my Valid Architectures setting in this project to $(ARCHS_STANDARD) in Build Settings.

This resulted in the following diff:

As not everyone will be using Xcode 11, I'm not suggesting this should be changed in the project file, but I thought it worth logging this issue in case others have the same problem and wish to clear the warnings.

Thank you for the detailed report! We'll switch to using $(ARCHS_STANDARD) going forward - probably should have been this way all along.
