Xcode build but launch app with black screen

Question

I have a problem with my xcode, all worked before but suddenly my app does not launch.

Xcode saying that it's launching but I just have black screen on simulator and nothing in the log...

I try on device but It's the same problem.

Edit : I tried with an other project and the app it's running.

Edit 2 : The problem come from storyboard... I will post a new ask. Thanks

Answer 1

You probably don't need this anymore, but I'm going to try to provide my answer for others out there.

Sorry if I'm violating the rules, etc. I'm new here. :)

Overall list of possible fixes (you guys have gotten here way before me, but I'll include them anyway--with credit).

• Sometimes, when it hasn't been used in a while (or if the project is new, etc.), the simulator takes a minute to load. This was mentioned by 68cherries.

• Did you check your storyboard entry point? I can't see it in the picture, but recently I've had it disappear a couple times. Just check "Is Initial View Controller"... see this picture .

• And finally... although this has been said by the great Jim ... did you try "cleaning" your app? This always helps me out.

Anyway, I hope I haven't bothered you and that this helps anyone who may need it!
