I am trying to log into Spotify with my Swift app and a new issue came up out of nowhere. After I do the OAuth dance, Safari redirects to my app, then:
- on my iPad mini (9.2.1), hangs forever on launch screen
- on client's iPhone 5S (9.0), crashes on launch screen
- everywhere else (iPhone 5 - 9.1; all simulators - 9.2), launch screen -> app -> works correctly
Deploy target is 8.2
Background
There are 7 apps that share a common codebase but branding and some redirect urls and such are different. Only one of them is behaving this way, all the others work as expected.
The most recent changes I made to the app were unrelated to any Spotify stuff. But we recently switched iTunes Connect accounts from mine to my client's and Spotify accounts from mine to my client's. This is the closest I've come to debugging it.
One thing that seems strange to me is in the Info.plist, the URL Types => Identifier. This has also changed and feels like it could be a cause. But in all of the Spotify ios-sdk docs, it makes it seem like an arbitrary string.
Crash is not showing up on client's crash logs.
Even if you don't have a solution, any debugging advice would be great. I have no clue how to debug something like this.
Thank you!
