Spotify WEB API from iOS App Can't Authenticate

[josephtclegg]

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.)]
