How do I remove the last update to my Xamarin ? I keep getting this error Error MT0091: This version of Xamarin.iOS requires the iOS 11.0 SDK (shipped with Xcode 9). Either upgrade Xcode to get the required header files or set the managed linker behaviour to Link Framework SDKs Only (to try to avoid the new APIs). (MT0091)
but when I upgrade to Xcode 9, there where too many bugs... so I need to just go back down.
