I can't even run a newly generated single page app in the simulator for iOS 8.4 or iOS 9.3. I have add no code at all to the newly generated app. I generated on VS for Mac (but I've also tried on VS 2017 on Windows). I get a white screen and then the app crashes before the Main entry point. Totally bombs out of the debugger so I can't even see what is crashing. No error msgs or anything - just terminates and disappears. I have tried many different simulator configurations (iPads, iPhones, etc....).
This default/generated single page add however does run on a real iOS 9.3 iPad - it's just the simulator that isn't working. I can also generate new empty XCode apps and they run just fine on the same simulator image for 8 or 9.
This makes it rather hard to continue to develop an app that we want to support as many iOS versions back as possible as our market unfortunately, is one where people hang onto older devices for quite a while.
Any ideas on how I can at least figure out where in the Xamarin frameworks that app is crashing? Or what I can do next to resolve this and move the project forward?
