The App store release of Xcode 8.0 (8A218a) crashes when trying to open or view old xib files (initially created for iOS 3 or 5). Xcode 8 not only crashes; but any attempt to relaunch Xcode 8 results in an immediate crash on launch before the project or xib can be closed or deselected. I had to move the xib file out of the project directory just to launch Xcode ever again. Xcode can build the app with the UIViewController that uses the old xib. It just can't view the xib (by clicking on the file name in the navigator).

Not sure how to fix or update the old xib file. Any ideas?

I have the exact same issue. Any help would be greatly appreciated!

If it''s of any help, my Xcode crash log is overe here gist [dot] github [dot] com [slash] thomax [slash] b338a8d02fb0c230fb1ec8e6cda41be9. Sorry for mangling that URL, but it seems the only way to avoid the moderation flag, and moderation around here seems to take a while.

Same problem. Same Xcode. Don't know exactly how old my file is; see header below.

I have filed bug

header of my file

One suggestion I found was changing useAutolayout from YES to NO. That didn't work for me.

A workaround.

De-downloading Xcode 7.3.1 and loading the nib in that version allowed a reference while building it in 8.0.

However I came across crashes when starting with a fresh nib, which I suspect are related.
