Using Xcode 12.2 I created an universal xcframework for all platform and noticed the following
watchos-arm64_x86_64-simulator

Note that there's no i386 mentioned, but there is a x86_64

So it looks like x86_64 became a valid watchOS simulator architecture at some point, along with the i386 that we supported.

With Xcode 12.2 Apple _silently_ dropped i386 (while adding arm64 for Apple-Silicon based Mac simulation). This does match the "Needs to be updated" deploy error (which is the same that happened when Apple dropped 32bits on iOS).

Re-enabling watchOS should work if we add a x86_64 slice to our watchOS simulator runtime - along with allowing the arch inside our tooling (e.g. mtouch).

This happened with Xcode 12.0, they mentioned it in the release notes.

Simulated watchOS 7 devices support 64-bit processes. To verify watchOS projects are 64-bit clean in Simulator, 
make sure ARCHS is set to its default value. (54654060, 66352876)

Note
Projects must be 64-bit clean in Simulator on Macs with Apple silicon, which don’t support 32-bit code.

I either missed it or forgot it :)

We got ourselves a branch of mono/2020-02 with watchOS sim with both i386 and x86_64 slices https://github.com/mono/mono/commits/2020-02-simwatch64 we could use this to test if we wanted to continue to support watchOS 7.1 simulators on xcode12.2

(For the time being, for those who are already on Xcode 12.2 pre-releases: you can go to Xcode Preferences, Components, download the watchOS 6.2.1 Simulator, make a new Simulator that pairs, say, an iPhone 11 with an Apple Watch Series 5, and choose _that_ in Visual Studio. It doesn't seem possible to download a 7.0 Simulator, alas.)
