Xcode 14.3.1 requires iOS SDK 16.4

[spouliot]

The mlaunch tool, part of the iOS SDK, is broken on Xcode 14.3.1.

This makes VSfM not show the simulators and, of course, deployments won't work.

Workaround

sudo dotnet workload update

This is a recurring issue with the .net iOS SDK (and the previous Xamarin.iOS SDK).

It might be a good idea to run something like /usr/local/share/dotnet/packs/Microsoft.iOS.Sdk/16.4.7067/tools/bin/mlaunch --listsim=X after the validation/installation of the SDK to ensure mlaunch works with the current Xcode.

On error we could suggest

• updating the iOS SDK, like dotnet workload update
• downgrading the Xcode version
• and filling an issue

I've made the change in https://github.com/unoplatform/uno.check/pull/152, this should be enough, though the simulators validation is not there yet.
