Answer 1

I have the same problem, I temporarily solved that by change product name to english. Seems it's a bug of Xcode GM version.

Answer 2

This bug seems to reappear every weekend for me! I have tried the other answers below with some success however, they do not always work. Then I stumbled across this post.

Comment from bdsinger: I get the crash in Xcode 6.1 GM whenever I resize the project window on external display at work after using built-in LCD display on retina mbpro all wkend. Crash report reveals the plugin as the cause. Uninstalled, crash went away. Would be more specific if I had the time, sorry. But nevertheless, thanks for the plugin and the effort!

It turns out to be an issue between my laptop, thunderbolt display, and Hyperdocks. Throughout the week I use my laptop at various places however, on the weekends I use my thunderbolt display.

Unplug your laptop from your external monitor, open your Xcode project (Yah! no crash), then reconnect it to your external monitor.

Note: Hyperdocks is a [paid] program that takes the best features of Windows 7 and integrates them into your mac. Such as resizing windows by snapping to the sides. Hence the crashed caused by resizing Xcode window using this plugin and swapping displays.

Answer 3

Same problem. It seems to be related to bridging headers. Removing the file (BridgingHeader.h for me) from the projet allow to open the project without crashing immediately !) Investigating…

Update: It seems that it was due to a "•" character in the project path ! Renaming the directory containing my projects from "• projects" to "projects" seems to have fixed the problem.

Answer 4

Same problem here. No special characters in path name.

Simply changing the project name file in Finder solves the problem. Another way that worked for me was to change the location project folder to my desktop.

Answer 5

Just delete all your xcode simulators derived Data, you can find derived data path at ~/Library/Developer/Xcode/DerivedData, woalaa... crash issue solved.

Answer 6

Simply changing the projects parent file name in Finder fixed it.

1) Change the file name of project.xcodeproj parent (Changing just .xcodeproj name did not work for me)

2) Open xcode

3) Close xcode

4) Change name back
