Set APPLICATION_EXTENSION_API_ONLY on a SPM package

Using Swift
50

Xcode 13.2 beta 2 did not resolve the issue for me, unfortunately. I can still reproduce it with my sample project (watch app + dynamic package).

I was able to silence the warnings by adding "-Xlinker -no_application_extension" to OTHER_LDFLAGS in my project settings. Alternatively, you can also specify this setting in your Package.swift file:

linkerSettings: [
    .unsafeFlags(["-Xlinker", "-no_application_extension"])
]),

I will report back if I encounter any issues with this workaround.
