Freeze if one of packages points to private repository

[Tunous]

One of packages in my project is a private GitHub repository. If this package is present in list of dependencies the command freezes with Username for 'https://github.com' printed to console. Entering text doesn't resolve the issue and script stays frozen.

If I remove that package from dependencies the command no longer freezes and correctly lists outdated versions.

Hi @Tunous, thanks for the issue!

Unfortunately I don't have a great solution for this right now, but the best workaround is to use passwordless SSH auth (or using the workaround in #17 for password-protected SSH keys), that way the internal call to git ls-remote will just work and not ask for credentials.

Another option could be to configure your git to use the system keychain as a credential helper (using git config --global credential.helper osxkeychain) which would also let git remember your credentials and not get swift-outdated stuck on the password input.

I think the best option for swift-outdated would be to error out in the case of being prompted for a password, but I don't yet know how best to approach that.
