I'm using Appcode 3.3 Build 143.381
I'm facing a bug with the build, related to all the "goto file", "goto class", "goto symbol" window.
Step to reproduce:
1. Open an existing project.
2. Select "navigate / class " from the menu or press cmd+o
3. Click on the filter icon
4. Try to select / deleselec one of the filter.
The view disappear and the changes on the fiter are not saved.
The windows doesn't disappear and the new options are applied.
