I get this warning:
*** NSForwarding: warning: object 0x3560018 of class '_TtCSs23_ContiguousArrayStorage0000000017DB45E4' does not implement methodSignatureForSelector: -- trouble ahead
Followed by an error
[SwiftObject doesNotRecognizeSelector:]
On line 2 of the following code:
let vcs = [feedTab, channelsTab, signinTab, historyTab, moreTab]
tabBarController.setViewControllers(vcs, animated: true)
Where each of the tabs is an instance of UINavigationController. This only happens on my device, not on the simulator. Any ideas?
The error was being caused by one of the dynamically linked libraries for Google Analytics. I had unlinked them and disabled GA, but the error didn't go away until I did a clean before rebuild.
