Link in an Editable NSTextView (like Apple's Notes) - swift

Question

I have an NSTextView that is initially set as read-only like this:
taskDescription.isEditable = false
I set a click gesture recognizer in viewDidLoad() on it like this so that when the user clicks the field, it gets set as editable.
override func viewDidLoad() {
super.viewDidLoad()
let clickGesture = NSClickGestureRecognizer(target: self, action: #selector(setDescriptionEditState))
clickGesture.numberOfClicksRequired = 1
taskDescription.addGestureRecognizer(clickGesture)
}
And here is the function called on click:
#objc func setDescriptionEditState(){
//Make it editable
taskDescription.isEditable = true
//Don't show automatic link detect while editing (I want plain text)
taskDescription.checkTextInDocument(nil)
//Put the cursor in the NSTextView
taskDescription.window?.makeFirstResponder(taskDescription)
}
Then when I load an NSAttributedString into it with a link in it, it shows up fine:
Last of all, I implement this delegate method for NSTextView:
func textView(_ textView: NSTextView, clickedOnLink link: Any, at charIndex: Int) -> Bool {
print(link) //<-- Never called
}
What's happening is the clickGesture is getting called instead of the link click. I know this because if I manually set the NSTextView to isEditable = false then the link works fine.
How can I allow the link click to happen while still allowing the user to click on the NSTextView to switch it into edit mode?
--- Update ---
I set the content of this NSTextView with an NSAttributedString. When logged to the console, it looks like this:
I want {
NSColor = "...";
NSFont = "...";
}a big link{
NSColor = "...";
NSFont = "...";
NSLink = "google.com";
} here.{
NSColor = "...";
NSFont = "...";
}
So the link is specified with an NSLink.

The key is to override the function "touchesBegan" and implement your own logic.
override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) {
let touch = touches.first
guard let location = touch?.location(in: self.view) else { return }
if !popupContainer.frame.contains(location) {
goodTouch = true
} else {
goodTouch = false
}
}
The variable "goodTouch" is established as a class property. You can then check the status of this variable at the beginning of the functions in question and then route your application appropriately from there. (This was specifically adapted from an iOS project I wrote, but should be the same for Cocoa). Make sure if you implement this, you reset the "goodTouch" variable to false after inspecting it to be ready for the next round of touches.
EDIT
I think this is a more appropriate response to your specific example, but I didn't want to delete the code from above:
override func mouseDown(with event: NSEvent) {
let textField = NSTextField() //this is for demo only...reference your actual object
let location = event.locationInWindow
let cgPoint = CGPoint(x: location.x, y: location.y)
if textField.bounds.contains(cgPoint) {
//fire the link here, over ride the click gesture recognizer
} else {
//change the editable style of the text field
}
}
