I have been trying to build a simple installer from a newly created template from Visual Studio for Mac.
New Project > Cocoa App
Nothing fancy really.
I can run the app in debug mode, but as soon as I enable the Create Installer Package option, it won't build.
Options > Build > Mac Build > Packaging : Create installer package (checkbox)
I always get this error:
/Library/Frameworks/Mono.framework/External/xbuild/Xamarin/Mac/Xamarin.Mac.Common.targets(3,3): Error MSB6006: "productbuild" exited with code 134. (MSB6006) (InstallerAttempt01)
I am using the latest Visual Studio Mac, and the latest Xamarin.Forms versions.
So, I must be missing something, and I don't really know what right now, as I can't find any info on this topic anywhere.
Just to confirm that this is a bug, me and one more developer have confirmed it.

Update: Apple is expected to fix this problem in the new version of macOS/XCode
