Bump min OS versions to match Xcode (14)?

[rolfbjarne]

The release notes for Xcode 14 (beta 1) say:

"Xcode 14 supports building applications that target macOS 10.13, iOS 11, tvOS 11, watchOS 4, and later."

Should we do the same?

Note that the underlying SDKs shipped with Xcode 14 seem to support building for earlier OS versions just fine, so we might get away with not doing anything for a while (i.e. it might be an IDE restriction only).

I wonder if that change removed the 32bits compilers...

Otherwise this is not the first time Apple bumped its requirements. Xcode 13.x can still build/install for older devices but can't launch them (you have to do it manually).

update

From the release notes

Building iOS projects with deployment targets for the armv7, armv7s, and i386 architectures is no longer supported. (92831716)

It's not clear if the command lines tools are still available (and they might be removed at any moment).

Looks like inmacOS 12.4 we are having issues installing the older sim (on CI, which is another world of problems):

It doesn't look like we need to do this for Xcode 14.

IMHO we should still do it at some point though, so I'm moving to .NET 8.

Resolution: Do it for .NET 8

This is complete now.
