Using SpotifyKit to export playlists

[theg3ntlem4n]

I'm a complete beginner to Swift but wanted to create an app that exports playlists to Spotify based on mood. I have a random array of Spotify song URI strings but for some reason, I cannot 1) connect the user to my app (ie: based on your test code, the picture and information do not update) and 2) figure out how to export a playlist.

If you could briefly explain how I could do that, I would really appreciate it.
