I installed the Xcode 7 beta 1 and it asked me to convert my code to Swift 2, which I did. All worked fine, there were only some problems with my apps test target. When that was solved, I built and ran the app and the error said: com.apple.interfacebuilder error 2001 I can't open the .xib and .storyboard files. It either won't open or Xcode crashes. What can I do?
Xcode 7 beta made my apps storyboard files inaccessible

seancook Jul 21, 2015 5:58 PM (in response to zurb) I experienced this, too, on El Capitan. NIBs wouldn't load, no Sims present, and unable to launch Simulators through the Xcode/Open Developer Tool/Simulator menu. After fighting it for a few hours I've finally got it working.
Here's what worked for me (YMMV):
I noticed a message in Console.app along the lines of the Simulator runtime not being code signed. I went to the path it described "/Library/Developer/CoreSimulator/Profiles/Runtimes" and removed the runtimes that I had there. They were old runtimes, so I assume that some check in Xcode now applies that didn't previously. Who knows?
After doing this, I could finally launch the Simulator via the Xcode/Open Developer Tool menu. Unfortunately, the Simulator still wasn't being shown as a run target in my workspace, so I kept spelunking...
I then went into the Simulator's Hardware/Devices/Manage Devices menu and added a new iOS9 device. It didn't seem to do anything, so I quit out of Xcode and Simulator.app. I then re-started Simulator.app (via Xcode/ODT/Simulator) and lo and behold the expected iOS9 simulators were displayed.
I closed and re-opened Xcode, changed the target OS for my project, and the Sims were finally displayed as run targets.
HTH.
Solution from apple forum. This helped me!
I fixed this by reinstalling Xcode 6 and unfortunately by changing Swift 2 elements back to Swift 1, I didn't back up. Then I deleted every Nib or Xib file in the project, but I did copy them separately in an other map. I could open these files, and copy and paste everything into new, replacing, Nib or Xib files of my project. I also had a problem with my test target, which I had to replace. Hope this helps for other people having the issue.
