As I tried to update Xcode to v.6.4 (6E35b) by using the App Store updater – the update procedure broke up with the error message
no HTTP response. After restarting the MacBook, the App Store, and the WiFi connection, the error message was still there. Funnily enough, I could update or download everything else!
I decided to uninstall the whole Xcode installation, but this doesn’t help in the end. The error message was still there as I tried to download and install Xcode from the scratch.
Based on that I downloaded the newest Xcode version from the Apple developer site and installed Xcode by moving the
Xcode.app file to the
After starting the fresh installed Xcode, an error alert popped out and told me:
Simulator verification failed Fortunately, I had a terminal open and could check the application folder. Unfortunately, I copied the Xcode application file with my personal user, and the Xcode application file inherited the permission.
rschulz@MacBook-Pro:~/www/$ ls -al /applications | grep Xcode drwxr-xr-x 3 root wheel 102B Apr 1 08:13 Docs for Xcode.app/ drwxr-xr-x 3 rschulz admin 102B Jul 2 07:36 Xcode.app/
This led to the error I described above because the other Xcode components (which I didn’t remove!) used a different
user:group permission (root:wheel). What I did was to change the file permission from
rschulz@MacBook-Pro:/applications$ sudo chown -R root:wheel Xcode.app Password: rschulz@MacBook-Pro:/applications$ ls -al | grep Xcode drwxr-xr-x 3 root wheel 102B Apr 1 08:13 Docs for Xcode.app/ drwxr-xr-x 3 root wheel 102B Jul 2 07:36 Xcode.app/
Xcode.app got the correct permission recursively, I could run Xcode without any error messages.
