Xcode 6.3 freezes/hangs after opening XIB file
After upgrading to Xcode 6.3 (release version), Xcode now freeze every time I open a XIB/Storyboard file that includes an IB_DESIGNABLE view that uses a custom font for any projects and includes a custom font (not necessarily to have reference to that font in that XIB/Storyboard). The freeze occurs after opening the .xib file and then attempting to switch to any other file. Xcode hangs and must be force quit.
I have opened a bug report with Apple. (Bug 20483867).
Right now, I have two work arounds.
- Download and use Xcode 6.2 from Apple.
- Remove the IB_DESIGNABLE tags from the custom view header files.
This is likely an Apple bug, but does anyone have a better work around or solution?
Answer
I've already suggested an edit for a more accurate description.
It only happens when your project contains a custom font. It'll freeze just by visiting any Storyboard/XIB that contains an IBDesignable custom view, not even referencing to that font in your Storyboard/XIB.
My workaround is to use have an older version of Xcode also installed (Xcode 6.3 beta or Xcode 6.2) and use that to update your Interface Builder files, and never open it in 6.3. open those Storyboard/XIB in a new window in Xcode with option+shift+click the file in the project tree.
Whenever you encounter the freeze, I use this command to clear the saved state just for that project.
rm -rf YourProject.xcodeproj/project.xcworkspace/xcuserdata
