I'm trying to implement custom NSTextContentManager and use it with NSTextView, however it seems that NSTextView expect NSTextContentStorage all the time.
final class MyTextContentManager: NSTextContentManager {
// ...
}
It's added to layout manager, and NSTextView instance finds it properly:
let textContentManager = MyTextContentManager() textContentManager.addTextLayoutManager(textLayoutManager)
however, when I use it, I see errors at:
[MyTextContentManager textStorage]: unrecognized selector sent to instance 0x600003d84870
the textStorage property is part of NSTextStorageObserving, that is not NSTextContentManager interface.
It looks like NSTextView is not ready to work with custom NSTextContentManager. What did I miss?

Add a CommentI am trying to provide my own NSTextLocation subclass and I encounter a similar problem: an unrecognized selector
rangeis sent to an NSTextRange instance that I create.It seems like it may be necessary to subclass every class in the cluster NSTextContentManager <-> NSTextLayoutManager <-> NSTextLocation to produce something that works.
Can Apple provide any guidance?
