Basic ssh-askpass in Swift
This is a very simple project which gets you a swift-ssh-askpass that is compatible with ssh-add in OS X.
Once built and installed somewhere you can get a GUI prompt for adding your keys by running:
DISPLAY=/dev/null SSH_ASKPASS=/Path/To/swift-ssh-askpass ssh-add < /dev/nullI implemented this in my system by creating a small Applescript that runs at login with the following command:
do shell script "SSH_ASKPASS=/Path/To/swift-ssh-askpass ssh-add < /dev/null"
