Hello,

In Swift, I'm using a custom Formatter subclass on a NSTextField (in a table) 
in IB. The textfield value binding is bound to a property of my model class. 
This property is a typealiased Int. I would also like to use KVC validation for 
this property, so my model class overrides 

validateValue(_ ioValue: AutoreleasingUnsafeMutablePointer<AnyObject?>, forKey 
inKey: String) throws

After changing the text in the textfield, my validation method is not called. 
When I replace my custom formatter with an instance of NSNumberFormatter, 
everything works as expected.

Any help with this would be greatly appreciated.
