Hello,
After adding <LangVersion>8.0</LangVersion> and creating an interface with default implementation, I get the following exception in Release mode: MTOUCH : error MT3001: Could not AOT the assembly
Please note that in Debug mode everything works as expected.
Steps to Reproduce
- git clone [email protected]:FortechRomania/xamarin-training-sample-app.git
- cd xamarin-training-sample-app
- git checkout feature/weakify-tableview-datasource
- open TrainingPreparation.sln and build for iOS Device
- Comment out iOS/ObservingPlainTableViewSource.cs (124) and the problem will disappear.
