I know this is duplicate question. DTAssetProviderService could not start DTXConnection with Simulator

But I did not found any solutions. Thats why I am asking again. I install the MacOS sierra and I install XCODE 8. In my mac I have xcode 7 and xcode8. But when I open the xcode 7 and when I run the code I am getting above error message.

DTAssetProviderService could not start DTXConnection with Simulator

But If I run the code in xcode 8 it is working.

What is the issue here?

NOTE:

  1. Clean build, derivedata clear, Kill the xcode, kill the simulator restart mac those solutions are not working.

  2. I have two mac. I checked with two macs. Both are having same issue

Fast fix:

  • Build app
  • The app will still install on the simulator, even with the error
  • Launch the app manually on the simulator
  • Go to Xcode
  • Click Debug > Attach to Process > Your App Name

This isn't really a "fast fix" since you have to do it every time you want to run your app.

Slower, but better, fix:

Reinstall Xcode from the Developer Center ("Other Downloads" page, thanks @milesper). Doing so will clear this error, and the app will run smoothly.
