Got a SIGABRT while executing native code.

Last week I had to update my mac and xcode and iphone to the latest, from that point on all my apps have been failing to build.
XCode is: 10.2
IOS is: 10.14.4
VS is 15:9:3
Xamarin is
Xamarin IoS and Xamarin Mac
Also deleted mac's cache and bin / obj etc (as usual)
All apps fail and did deploy prior to update get the same or very similar error.
Really appreciate any help. I've only been able to progress in Android

    If you have updated your Visual Studio for Mac to the latest, you should also update your VS for Windows to match the pairing.
    As the latest Visual Studio for Mac is using Xamarin.iOS 12.8, you have to install Visual Studio 2019 on your Windows.
    And I'm a little confused about your iOS version. You said you have updated the iOS too, but the latest iOS version is 12.2.
    You have to keep all the related tools using the same version then test a blank project to see the result.

    Thanks LandLu
    Looks like you're right, I'm taking the plunge to 2019, Seems very soon after its release - I'll let you know.
    The Versions were simply taken form the current 'Help About' on relative apps.
