Ok, I got my Visual Studio Android emulator working, see prior blog post. Now focusing on IOS debug-run with a connected Mac. I got the following error..
Severity Code Description Project File Line Suppression State
Error Could not copy the assembly '/Library/Frameworks/Xamarin.iOS.framework/Versions/10.4.0.97/lib/mono/Xamarin.iOS/mscorlib.dll' to '/Users/davidyardy/Library/Caches/Xamarin/mtbs/builds/App1.iOS/820c43b5a93f812c648bedcbb5cd7ad5/bin/iPhoneSimulator/Debug/App1.iOS.app/.monotouch-64/mscorlib.dll': Access to the path "/Library/Frameworks/Xamarin.iOS.framework/Versions/10.4.0.97/lib/mono/Xamarin.iOS/mscorlib.dll.mdb" or "/Users/davidyardy/Library/Caches/Xamarin/mtbs/builds/App1.iOS/820c43b5a93f812c648bedcbb5cd7ad5/bin/iPhoneSimulator/Debug/App1.iOS.app/.monotouch-64/mscorlib.dll.mdb" is denied. App1.iOS
I made sure that my Mac Agent was connected and all seemed good there. I opened the with Xamarin Studio (on the Mac) and had the exact same error. Ok so this error is not isolated to only Visual Studio (or worse yet just 2017). I now have the problem on both Mac and Windows. This could be related to the beta release/channel of Xamarin.
Ok, so the resolution was found with this bug/resolution posted here https://bugzilla.xamarin.com/show_bug.cgi?id=52113
The full workaround is: > sudo chmod 0644 /Library/Frameworks/Xamarin.iOS.framework/Versions/Current/lib/mono/*/*.mdb
