I have used IQKeyboardManager library in my app. i installed IQKeyboardManager via cocoapods. Done button is not showing up on each keyboard. that is invisible.
here below my code that i have set in AppDelegate.swift file.
IQKeyboardManager.shared().isEnabled = true
The solution you are looking for is
Change Return Key to Done in property of UITextfiled at which which you want to show Done button.
