Server SSH Fingerprint Failed to Verify

I've got a local Swift Package Manager package that uses a private Github repo as a dependency. When I open the local package with Xcode, it fails to “Resolve Packages” with this error:

Error while fetching remote repository: [email protected]:mayoff/Preamble.git

Server SSH Fingerprint Failed to Verify

Xcode error log showing the errors described above

However, if I use the command line swift program, it can clone the private repo. For example, I can run swift package show-dependencies in the local package's directory without complaint. I can also successfully clone the remote package repo with git clone. So it's not a problem with my .known_hosts file or my SSH key.

How do I fix Xcode's complaint?

Solution

  • So it turns out the “Server SSH Fingerprint Failed to Verify” error message in Xcode's log navigator is double-clickable. Who'd have guessed?

    Anyway, double-clicking the error message brought up a dialog box that let me tell Xcode to trust the Github server:

    After I clicked the Trust button, Xcode was able to clone the remote repo.
