问题
I'm trying to add a remote linux SVN repository to my project but when I enter the server address I get the message Host is unreachable.
I'm entering it like
svn://ip_address/myproject/
From terminal I can do this
svn list svn://ip_address/myproject/
and it shows the contents without any issues.

I had this problem as well in linking to a Git repository. It seems XCode has some issues with IP addresses. I found that by modifying my hosts (/private/etc/hosts on Mac) file and adding an entry for the repository's IP address does the trick.
Hosts file entry:
i.p.add.ress serverName #where i.p.add.ress is your ip_address
In the Location field in XCode:
svn://serverName/myproject
The comments above referencing the other question's answer doesn't cover the IP address issue. Hopefully this will fix your issue too.
回答2:
To modify the host file you open the terminal and put this command:
sudo nano /private/etc/hosts
Now you have opened with "nano editor" the file hosts, add IP, save and close. After you put this code in the terminal to reflush dns:
dscacheutil -flushcache
END!

This is probably not the solution to the issue the original poster was experiencing, but the same error message can be received for a different reason, which is why I post this.
Xcode has trouble with ssh login banners.
Quite simply, if your svn server is accessed via svn+ssh and is making use of a login banner, Xcode will state that your repository cannot be reached. Comment out the Banner entry in /etc/sshd_config, and there should be one less reason why you cannot reach your repository.

I also came across this with hard luck. How I fixed my broken repository is as follows.
- Start XCode and check out or clone a new repository.
- Copy the git HTTPS clone URL.
- Paste into the Xcode field and remove the "S" of HTTPS.
- Press clone button
- When the "verify Certificate" popup appears make sure to set it to "Always Trust"
- If needed to enter git username password save that to the keychain.
- In the original "broken repository" Open the XCode organizer click the remotes folder and expand "origin"
- If no branch appears enter username and password and the remote will now appear
Hope this helps
