xCode 4 hangs… what to do?

xCode 4 started to hang on any project under svn control. I use a remote repository which is accessible and works just fine from a command line. The only work around I was able to find is to kill local svn and checkout the whole project again. That seems to work for a bit but then the same problem shows up: xCode just hangs solid a few seconds after I start it. I would really appreciate any help to resolve this... Can't do anything :(

Please and thanks.

Log shows the following:

Renaming my working directory also worked for me. It is a pain but i just rename it back when I need to do a check-in. Also note, that I updated to xcode 4.0.2 this morning and it has the same problem.

Deleting if from "Organizer -> Repositories" does help.

I do have the same problem and can workaround temporarily by renaming the local working directory on my MAC.

I had multiple checkouts from same repo, deleting duplicates solved my problem.

I had the same problem. Every time I tried to open a project in XCode 4.0.2 GA, I'd get the beach ball and eventually the stack trace above. My subversion repository is on a remote host that I am connecting to over ssh. When I looked at the repositories under Window > Organizer the repository in question was in 'yellow' status. XCode seemed to be stuck trying to check out the code.

I did two things

1) Set up key authorization instead of password. This didn't do much.

2) I removed the svn repository on the remote host. On my local host I found all of the the .svn directories

find . -name '.svn' -print

and deleted them. Then I updated the global ignore list in the ~./subversion/config directory to look like

global-ignores = *.o *.lo .la ## .*.rej .rej .~ ~ .# .DS_Store *.mode1v3 *.pbxuser build xcuserdata

It was freezing on the xcuserdata directory.

Then I recreated the subversion repository on the remote host and reimported the project from my local host.

Now it seems to work!

I am not sure the impact this will have on multiple users editing the project. I am using svn to keep the project sync'd among my own machines.

Hope this helps, rdp
