I have a bug since mid january where deploying a second time my app in the simulator using CTRL-F5 will deploy then start the app, but with a black screen. The solution is to kill the app in ios and tap the app icon. Then it shows ok. But it's tiring.
Maybe someone have found the root of this pb and have a fix ?
versions: xcode 5.1.1, xamarin stable/beta (won't change anything). Pb happens with both Xam studio and VS.
