This don't make sense.
Apple own header have errors inside, maybe this will be solved until Xcode 15 release, but we don't even use this, so there is no harm in removing it and save a few bits.

I pushed a commit that fixed a couple build errors when I tried running this locally. Not sure how the watchOS samples ever worked before this.

One was:

/sentry-cocoa/Samples/watchOS-Swift/watchOS-Swift WatchKit Extension/ContentView.swift:6:6 'StateObject' is only available in application extensions for watchOS 7.0 or newer

The other was an error complaining that the embedded binary wasn't signed with the same cert as the parent app.

[brustolin]

Strange, i had no problem running the sample here.
Thanks @armcknight for the help.
Since I'm the owner of this PR we need you to approve it.
