I am running the latest version of Visual Studio and the latest version of unity. When I open the project using Visual Studio for Mac, I am able to rebuild the app.
But, when I try to start debugging, I am getting Execution Failed without any explanation or build output.
I am able to run the app successfully on iOS through Xcode, although the iPad is refusing to start the app automatically and I have to open it manually.
The issue is that , I can't start the app on Visual Studio for Mac.
Apparently, If you open multiple instances of Unity, Visual Studio for Mac will get confused and will not know which project to attach to.
Having one instance solved the issue for me.
