No, but the reason for that and for the trouble you’ve run into is a bit
complicated.
First of all, you are actually talking about bind *thro

Actually, it works as far as the text field displays “Multiple” (placeholder)
for multiple values, but it doesn’t work when I set a value in the text field.
In that case I get:
Error setting value for key path selection.sel
Bingo and thanks!
I had already found the checkbox for “Selects All When Setting Content"
The missing piece of the jigsaw was using “selection" as the Controller Key and
“self" as the Model Key Path.
It all works now.

Yep, you’re very close. An array controller is required indeed, it’s the one
responsible for vending out NSMultipleValuesMarker.
From your earlier message, you’re now seeing an exception or similar:
Cannot create number from object <_NSControllerObjectProxy: 0x600070b0> of

I think I must be missing something obvious.
The value of an NSTextFie
Sounds like NSValueTransformer is in fact what you need.
It can take in your NSArray ref and spit out a single NSString that the
NSTextField binding can live with.
Defining NSValueTransformer subclass for every binding can be a pain.
So I use a block approach. This has the big advantage that you

In the case of the single value, the text field is set up via the Bindings pane
of Interface Builder so that “Value" says “Bind to File’s Owner” with a model
key path of self.value. (And “value" is decla
From what I understand of your example, you’re not “binding” anything in a
Cocoa sense.
What you is an NSArrayController. Bind your text field to the array controller.
Supply the array controller with content, and have it derive the selected
value, be it single or multiple.

Hi,
This seems like an elementary question.
I’d like to bind an NSTextField to an array of numerical values, so that the
text field will either display a single value if the values are identical or
will display a multiple values marker if the values are different.
Using Swift, I can bind a tex
