Answer 4

Killing the simulator and restarting it from Xcode helped me.

You are probably using macOS Sierra which breaks Xcode 7.3.1 (mac store version)

Use Xcode 8 beta or Xcode 7.3.1.dmg downloaded from the Mac Developer portal for a fix https://developer.apple.com/downloads

Direct link to Xcode 7.3.1: http://adcdownload.apple.com/Developer_Tools/Xcode_7.3.1/Xcode_7.3.1.dmg

Answer 5

Simply delete the old App from the simulator by going to: Hardware -> Home (Here, you will be returned to the home screen of the simulator). Now press and hold the old app icon on the simulated 'home' screen until all the apps start wobbling. Tap the cross and you will be asked to confirm the deletion.

Now build your app again and all should be fine.

Answer 6

For me, it was an issue with having WebSense installed by my IT department. It is known to inject libraries into other processes such as Simulator. Once removed, it was working again.
