Everything was working fine on xcode 7.3.1, Than I have to add braintree 3ds sdk which is supported on xcode 8. So, I migrated the code to xcode 8 and than xcode 9. Now, build working fine on below IOS 11 but on ios 11 and above app is crashing before opening new main screen. I am new to Ios please help.
it's crashing on this line :
let vc = storyboard?.instantiateViewController(withIdentifier: "KbNav") as! KabNavigationController

I have searched and debug my code alot keep in mind always enable exception break points to trigger exactly which line causing the crash. You can learn it from this Exception Breakpoint in Xcode . I found my solution here https://github.com/aryaxt/iOS-Slide-Menu/issues/250.
move these two lines from setup function to viewWillLayoutSubviews of Slide Menu.
//moved this from the `setup` function:
self.enableShadow = YES;
self.enableSwipeGesture = YES;
