Starting with Xcode 11, Apple stopped distributingApplication Loader, which was used to publish Apps to the iTunes Connect website.
We updated our MSBuild tasks to make use of a new tool shipped with Xcode:altool.
This is a necessary step for the IDEs tocontinue providing the ability to publish Apps to the App Store.
This version of Xamarin.iOS corresponds to ourxcode11 milestone and is based of the16.2 release.
Tip
This version can be used to submit Apps to the App Store.
