Build failing on Xcode 14.3 for WatchOS (arm64, i386, x86_64)

[kerrmarin-lvmh]

• [x] I have read CONTRIBUTING and have done my best to follow them.

What did you do?

1. Clone this repository
2. Open Nimble.xcodeproj
3. Set scheme to Nimble-WatchOS
4. Set device to "Any watchOS Simulator Device (arm64, i386, x86_64)"
5. Product -> Build (CMD + B)

What did you expect to happen?

Nimble will build successfully

What actually happened instead?

Environment

List the software versions you're using:

• Quick: ?.?.?
• Nimble: main branch
• Xcode Version: Version 14.3 (14E222b)
• Swift Version: Xcode Default

Please also mention which package manager you used and its version. Delete the other package managers in this list:

This happens when building in Xcode, but also in Carthage 0.39.0

I should also mention that updating the minimum deployment to WatchOS 7.0 fixes the issue 🤷

Thanks @younata !
