Got an error building a release version of an app where I have a binding project against Sparkle that's just started failing as soon as I updated from Xamarin.Mac 3.0 to 3.4 (and the rest of the 15.2 release).
Attached is an example project that exhibits the problem - just do a release build and it'll fail. The relevant bit of the build log (I suspect) is this:
Undefined symbols for architecture x86_64: "_OBJC_CLASS_$_SUUpdater", referenced from: objc-class-ref in registrar-4205f1.o ld: symbol(s) not found for architecture x86_64 clang : error : linker command failed with exit code 1 (use -v to see invocation)
Any idea what's changed and that I'm doing wrong? As I say, built and worked previously, now won't build.
