Greetings,I've been struggling some time with this issue. I have this App which I'm developing a Messages App Extension. App works fine but I can't debug it. I can add NSLog sentences to check for workflow but when I try to add a breakpoint it won't stop there, even if the NSLog nearby is triggered (i.e. It doesn't stop on a breakpoint in viewDidLoad from my MSMessagesAppViewController subclass). I've tried to create a project from scratch and it works fine. It's just with this project (created from XCode 7) that I'm not able to hit any breakpoint. I've tried deleting the extension and recreating a new one with no success. When I try to debug the App target It works just fine, it's this extension target I cannot reach any breakpointAny ideas?
