10.11 SDK note

[JanX2]

Just making sure that you have seen this. From the deprecation note for -insertText: in the 10.11 SDK.

Use -insertText:replacementRange: from NSTextInputClient instead. Since the method is designed to be used solely by the input system, the message should never be sent to a text view from applications. Any content modifications should be via either NSTextStorage or NSText methods.

Hey, nice catch, and thanks for the heads-up!

From my (very brief) playing around with it, it seems like the sample code here works equally well by calling (and overriding) insertText:replacementRange:. I'll probably move over to using that in my real code (and update this sample if so).

Regarding the warning that applications shouldn't use insertText:replacementRange: for content modifications, yeah, that's pretty similar to the warning they used to have on insertText:, which is what prompted this sample code.
