Until now, these were haphazardly enforce inline in blueprint
implementations. The only thing stopping complete breakage is that
`EndPlacement` wasn't called (too much) from outside the blueprint,
leaving them responsible for their own placement.
By moving this conditional out of the provided paramters to
`EndPlacement`, it allows more flexible usage of that method externally.
Coming in a future PR.
A new version of `Microsoft.iOS.Sdk` was released on
2023-05-09T17:28:41.7300000. This version requires Xcode 14.3, which is
not currently available on `macos-latest` runners (which currently alias
to `macos-12`).
To fix, migrate to `macos-13`, which is currently in beta, and
explicitly use Xcode 14.3 (because even on the `macos-13` image, Xcode
14.3 is not yet the default).
