I tried to run an existing app in the iOS 9 simulator but all I get is a black screen with a white apple logo and a progress bar. It looks like the simulator is downloading a new version of iOS? It's been sitting there for 15 minutes without moving. What's going on?
I flailed around trying to fix this same problem. Here's what eventually worked, and some steps are almost certainly pointless:
Out of curiosity, do you have the simulator showing an external display from under Hardware > External Displays?
I eventually found that the simulator will hang on the black screen / white Apple logo when it gets started with an external display window active. My workaround in Beta 2 is to close the display window, re-run the project, then turn the display window. You may get a Springboard crash (and log) when you close the external display window, but the sim will carry on.
I had this issue and following steps 1,2,3 and 5 were sufficient to get the simulators working again.
Thank you
I tried this minus step 4 and it didn't work for me. =(
For me the problem turned out that the main view controlelr got never loaded (which I confirmed through breakpoints).
What fixed the problem for me is to recreate the storyboard:
(1) add new story board to your project
(2) copy & paste the contents of the old story board to the new one (just click on the white area, hit command-a and copy)
(3) paste in the new (empty) story board
(4) set the entry point in the new story board (you will get a runtime error if this is not done)
(5) update your plist to use the new story board
(6) delte the old story board
(7) be happy
Almost happy :-)
Unfortunately, by coping the storyboard, new IDs are being generated, so taking over the localization is a pain.
Hope there is an easier solution ...
