In the latest updates, the app I am testing using the simulator cannot be removed. Clicking on the quick menu with the option to 'Remove App' does not yield any result. Another issue pertains to running the app.
Two out of three runs are successful, but on the third attempt, I encounter a black screen or have to wait up to 5-10 minutes before the run. Xcode status bar shows message: "Installing ... to iPhone ..." The only solution is to close and restart the simulator, which doubles the time required to work on a single feature.
