More Swift 3 fun! I have a class that overrides controlTextDidEndEditing as such:

  override open func controlTextDidEndEditing(_ obj: Notification) {

    }

According to the headers and everything I can see - this should be correct:

extension NSObject {
    open func controlTextDidBeginEditing(_ obj: Notification)
    open func controlTextDidEndEditing(_ obj: Notification)
    open func controlTextDidChange(_ obj: Notification)
}

However I get the warning:

: Instance method 'controlTextDidEndEditing' nearly matches optional requirement 'control(_:textShouldBeginEditing:)' of protocol 'NSControlTextEditingDelegate'

Well that’s odd. You should definitely file a bug about this. Please post your bug number, just for the record.

Are there any drawbacks with implementing both methods? If not, that seems like your workaround.

Urgh, informal protocols.

Can you post some more context for this? I tried this out in a simple macOS test project and didn’t get the warning.

import Cocoa

class O : NSObject, NSControlTextEditingDelegate {
    override func controlTextDidBeginEditing(_ obj: Notification) {
    }
}

Hi Quinn.

You are testing DidBeginEditing and I'm using DidEndEditing. Shouldn't make much of a difference, but here's the interesting thing. If I just have

  override open func controlTextDidEndEditing(_ obj: Notification) {
...code goes here...
    }

by itself - I get the warning. If I add an empty:

  override open func controlTextDidBeginEditing( _ obj: Notification) {
  }
  override open func controlTextDidEndEditing(_ obj: Notification) {
...code goes here...
    }

No warning…

Context - its a Swift-based private framework for my app.

open class FSRichTextEditorController: NSViewController, FSRichTextEditor, NSMenuDelegate, NSComboBoxDelegate, NSTextViewDelegate, NSTextStorageDelegate, QLPreviewPanelDataSource, NSPopoverDelegate, NSControlTextEditingDelegate {

Its a decent workaround. I'll file a bug shortly. I've got quite a few already in RADAR 🙂
