like @Jesse_Jiang also noticed in this thread there are issues on debugging in the iOS Simulator.
I'm having a hard to to start the app in the simulator. It seems get stuck in a crash-loop when XS tries to start the app. The app pops open for a very short time and then closes again. This process keeps on continuing.
Some times I'm able to start it again, by closing XS and the simulator, clearing the bin/obj folders, and start it all over again. But currently I'm unable to start it using workflow.
I don't know how to get more detailed information about what's going wrong.
