UITextViewDelegate method gives "Use of undeclared type URL" error in Swift 3 and Xcode 8.0

When i implement the func textView(_ textView: UITextView, shouldInteractWith URL: URL, in characterRange: NSRange) -> Bool OR func textView(_ textView: UITextView, shouldInteractWith URL: URL, in characterRange: NSRange, interaction: UITextItemInteraction) -> Bool method in my swift class, it gives error and warning as shown below.

error : Use of undeclared type 'URL'

warning : Instance method 'textView(_:shouldInteractWith:in:)' nearly matches optional requirement 'textView(_:shouldInteractWith:in:)' of protocol 'UITextViewDelegate'

If I Change the class name to NSURL instead of URL, it compiles properly but warning never goes off.

Also the above methods are not called while interacting with URL in my textView

Thanks!

Try changing the method header to something like this:

func textView(_ textView: UITextView, shouldInteractWith url: URL, in characterRange: NSRange) -> Bool

(The formal parameter url needs to be in lower case.)

This definitely is a bug of Swift/Xcode. The formal parameter URL is shadowing the type URL.
