Uploading iOS Apps Created with Xamarin
For Xamarin-based apps, you need the file with an .app extension. Once you have that file, you may zip it up and upload it to AppAssurance.
If you are trying to generate that file, we recommend you first try running your Xamarin app in the iOS Simulator on a Mac Computer. That process will generate the required .app bundle for you. Then you can locate it, zip it, and upload to AppAssurance. It is often found in a path like:
[Your iOS Project Folder]/bin/iPhoneSimulator/Debug/[Your App Name with extension iOS or .app]
