Thread 1: EXC_BAD_INSTRUCTION (code=EXC_I386_INVOP, subcode=0x0)

[chumendaiyibeigouqi]

Hi,I used xcode 11, ios 13, to create a new project, run it on the device, and encountered an error. Projects created in Xcode10 will not be encountered using FAPanels.
Xcode helped me locate it here.

let rootController: FAPanelController = window?.rootViewController as! FAPanelController

error: launchOptions = ([UIApplication.LaunchOptionsKey : Any]?) nil

Hi @chumendaiyibeigouqi

Can you please make sure the root controller in main storyboard is FAPanelController?

If yes then please share some more details how are you using it.
