Hey there! I installed macOS Sierra and XCode 8. I played a bit with swift 3, but after some time I wanted to get back to Swift 2. So I started XCode 7, but when I tried to run an app on the simulator, XCode showed an error.

I've checked some other post about that problem and tried everything, but nothing works. I've already killed XCode and the Simulator, restarted my Mac, deleted the DerivedData, deleted XCode-beta and reinstalled XCode.

Error: DTAssetProviderService could not start DTXConnection with Simulator 'iPhone 6'. Check the system log for errors.

System: Macbook Pro 13", 8GB Ram, 512GB SSD, Intel Core i5 2.8GHZ;

Don't know how to post the system.log, doesn't work with the code brackets. How can I upload the file?

EDIT: try this: http://www.mediafire.com/download/821qz82vwiky38t/system.log

I hope you can help me, sorry for my bad english, I'm Austrian :P

I had Same problem. Use your device with development certificates. It will work on device with no errors. This issue is only with simulators.

For Simulator: Here is a workaround.

You Application has been installed to simulator. Run it from simulator now. To debug application use debug menu of Xcode to attach with application.

I assume this will be solved with release of stable version of macOS.

Thank you
