macOS NSTextInputClient

[MrFusion]

I have a subclass of NSResponder that implements the NSTextInputClient protocol.

One of the required functions is this one:

- (void)insertText:(id)aString replacementRange:(NSRange)replacementRange

In whatever user input I give, I never seem to get a valid replacementRange.

NSLog(@"%@",NSStringFromRange(replacementRange));

Does anyone know under which circumstances a valid range is supposed to be given?
My code works since I just use the selectedRange (also a required function), but I want to make sure I don't miss anything here.

The "TextInputView" sample code implements this function as well, but overrides the replacementRange (in most cases?).

Your insight into this function is appreciated!

I type in any letter -> I get {9223372036854775807, 0} -> I expect something like {4,0} (no selection) or {4,6} (with text selected). (0,4 and 6 are random examples.)
Likewise, TextInputView gets a {very large number,0} as input.

Find the selectedRange method and read what it says is the range when there's no selection. Then look up what NSNotFound is. Maybe even print it out in your code.
