How to identify the iOS version in Xamarin.iOS
I am able to get the iOS device version using
UIDevice.CurrentDevice.CheckSystemVersion(7, 0)
The above method returns the BOOL value true, if the device version is above (or equal to) iOS 7. Otherwise it returns false.
Even if this is too late but it might helps somebody else. You can get the iOS version, running on your device, in your Xamarin.iOS project(in AppDelegate.cs) this way:
string targetOS = UIDevice.CurrentDevice.SystemVersion;
Debug.WriteLine("iOS version: ", targetOS); // =In my case=> iOS version: 12.4.4
Xamarin.Forms version 4.3.0
