XCode 4.2 SVN issues

None of the above worked for me BUT here is what worked:

I continued to get the "untrusted certficate" error in xcode 4.2 -- i could see that a prompt is being presented as readonly in xcode

So, I accessed my svn server site from via the svn command prompt utility and did a dummy operation :

svn co https://mysvnserver.com/project/

I saw the same error on the prompt as in xcode:

Error validating server certificate for 'https://mysvnserver.com:443': - The certificate is not issued by a trusted authority. Use the   fingerprint to validate the certificate manually!Certificate information: - Hostname: *.svn.mysvnserver.com............R)eject, accept (t)emporarily or accept (p)ermanently? 

Now here is the key : I hit a p here to accept (p)ermanently, and I was able to access the repository via the prompt. Next, I opened xcode and opened the repository -- everything worked flawlessly.

I had issues similar to yours, I suggest you try:

1. Close Xcode + Organiser
2. Open your svn web address in Safari (not any other browser) - using the dns name
3. It should come up saying the address is untrusted as the cert is a different name / address
4. Click show certificate and then tick the box saying always trust then continue
5. it may prompt you for your mac username / password to add to the keychain
6. Open xcode and try again using the DNS name..

The issue with xcode and accessing svn servers which have HTTPS certificates which fail any of the checks (be it host matching, self signed etc..). Opening the addresses in safari and adding as trusted solves this problem!

Run command in Terminal

svn info https://example.com/svn

It will then prompt you the "(R)eject, accept (t)emporarily or accept (p)ermanently?"Press p and problem will be solved
