Spotify WEB API from iOS App Can't Authenticate

Hey guys, I'm trying to build an iOS application which makes use of the Spotify WEB API for a school project. Basically I want to be able to authenticate through Spotify in the app and then be able to search and play songs on a phone with Spotify installed. Easy. However I'm having some trouble when I try to authenticate through Spotify. A dialog box pops up saying "AppName wants to Use Spotify.com to Sign In" with two options, Cancel, and Continue. I press Continue. A page briefly pops up before going away, and in my console I see the following error message:

[Error: The operation couldn’t be completed. (com.spotify.sdk.login error 3.)

The data couldn’t be read because it isn’t in the correct format.]

What is an error 3? Where can I see the definition of this error? My redirect URI is a deep link pointing to a page in the app. My token swap/refresh server is running as a heroku application. I am building through XCode and testing on a physical iPhone. Anyone have any suggestions?

Update: Trying to authenticate through the iOS emulator takes me to a Spotify login page but gives me this error after trying to log in:

[Error: The operation couldn’t be completed. (com.spotify.sdk.login error 1.)

An SSL error has occurred and a secure connection to the server cannot be made.

The operation couldn’t be completed. (kCFErrorDomainCFNetwork error -1200.)]
