DTAssetProviderService could not start DTXConnection with Simulator
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

This turns out to be 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.
Xcode 7 or 8 issue with Pods, can't run at all
I got mine working now!! Not really sure what I did, at all, but I just deleted the Xcode 8 .app entirely and then I redownloaded it, opened up my project in it, did a pod install and pod update, and it's running in the simulator just like normal! Not sure what I did at all, but redownloading is worth a try, it is in fact possible to fix.
