The method
[FTAViewController viewDidLoad]
was incorrectly calling[UIApplication openURL]
on a non-main thread. This resulted in the "main thread checker" in xcode always flagging this as an issue. It's also technically undefined behavior.This PR fixes the bug by scheduling the
[UIApplication openURL]
to run on the main thread instead of calling it directly in a worker thread.
