App crashes when pressing link on UITextView

As mentioned in this Apple Forum post, I implemented the following UITextViewDelegate and it solved my issue

func textView(textView: UITextView, shouldInteractWithURL URL: NSURL, inRange characterRange: NSRange) -> Bool
{
    UIApplication.sharedApplication().openURL(URL)
    return false  
}  

@Louis Tur: Thanks for the link

Swift 5.2

 @available(iOS 10.0, *)
func textView(_ textView: UITextView, shouldInteractWith url: URL, in characterRange: NSRange, interaction: UITextItemInteraction) -> Bool {
{
    UIApplication.shared.openURL(url)
    return false  
}

@available(iOS, deprecated: 10.0)
func textView(_ textView: UITextView, shouldInteractWith url: URL, in characterRange: NSRange) -> Bool {
{
   UIApplication.shared.openURL(url)
   return false  
}

My fix for the crash was to implement both the deprecated and its replacement delegate methods.

/// Gets called if iOS version is >= 10.
@available(iOS 10.0, *)
func textView(_ textView: UITextView, shouldInteractWith URL: URL, in characterRange: NSRange, interaction: UITextItemInteraction) -> Bool {
    return textViewShouldInteractWithURL(URL: URL)
}

/// deprecated delegate method. Gets called if iOS version is < 10.
func textView(_ textView: UITextView, shouldInteractWith URL: URL, in characterRange: NSRange) -> Bool {
    return textViewShouldInteractWithURL(URL: URL)
}

func textViewShouldInteractWithURL(URL: URL) -> Bool {
    // common logic here
}
