Xcode 6.3: Crash When Navigating From a Storyboard

Originator:anthony

Product:Developer Tools Product Version:Xcode 6.3 (6D570)
Classification:Serious Bug Reproducible:Always
 
Summary:
Xcode slowly crashes when navigating away from a storyboard. Everything within the storyboard appears to work correctly, however, as soon as another file is selected in the navigator, or certain other actions are performed, the application spins indefinitely.

Steps to Reproduce:
1) Open a .storyboard file. The file being tested includes:
- Designable objects with configured properties
- Multiple scenes with segues
- Fairly complex auto layout constraints
2) Select a different file (reproducible at least with source files, project files, asset catalogs, or resource)

Expected Results:
Xcode will display the selected file.

Actual Results:
Xcode shows a spinning beachball indefinitely.

Regression:
This problem was not observed before upgrading to Xcode 6.3. No other obvious changes were made to the project, files used, or workflow when this problem began.

Notes:
Following this note: http://stackoverflow.com/questions/29542356/xcode-6-3-crashes-when-navigating-from-storyboard-to-other-swift-1-2-file Commenting out all IB_DESIGNABLE’s across the project (using a different editor, obviously) appears to circumvent this issue.
