After migrating my framework to Xcode 10 beta (10L176w) I started to get warnings like:

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.

... and:

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

Despite these warnings the build and the unit tests all pass Ok. I'm using Swift 4.2.

Still, what are these warnings about?
