Attempting to renew session from Spotify so I can retrieve new access and refresh token. Starting on the first print line, I receive the fatal error.
@IBAction func renewSession(sender: AnyObject) {
let auth = SPTAuth.defaultInstance()
auth.tokenRefreshURL = NSURL(string: tokenRefresh)
auth.tokenSwapURL = NSURL(string: tokenSwap)
auth.session = self.spotifySession
auth.sessionUserDefaultsKey = sessionKey
if (auth.session != nil) {
SPTAuth.defaultInstance().renewSession(SPTAuth.defaultInstance().session, callback: {(error, session) -> Void in
if error != nil {
print("The renewed Spotify session is", session)
print("The renewed canonical user name in the session is", session.canonicalUsername)
print("The renewed access Spotify token in session is - %@", auth.session.accessToken)
print("The renewed encrypted refresh Spotify token in session is - %@", auth.session.encryptedRefreshToken)
print("The renewed expiration date of the Spotify access token is - %@", auth.session.expirationDate)
} else {
print ("The problem with the renewal session is", error)
}
})
}
You should be checking if session != nil
, not if error != nil
. There is some error
but your code is moving control to the incorrect flow.
