Top/Bottom layout guide is deprecated since iOS 11.0 So you have provide to IQLayoutGuideConstraint with safe area. While dismissing keyboard, it leaves black screen onto that portion (Please refer to the image).
I'm tried using CocoaPods pod 'IQKeyboardManager' and pod 'IQKeyboardManagerSwift' ~ 5.0.0.
