DTAssetProviderService could not start DTXConnection with Simulator

Question

After updating to Xcode 7.3 I am not able to run my app in the iOS Simulator.

On every attempt I am getting the following error message:

DTAss

Answer 1

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
