when you do self.myInt under the covers you're really doing [ self
setMyInt:123 ], and that method is KVO compliant so it fires the
property change notification the textfield needs.
myInt = 123 just sets the variable directly and skips the property
change notification.

I'm trying to learn how to use bindings. MyObject has an NSInteger
myInt. I used @property and @synthesize to make myInt into a
property. In IB I bound an NSTextField to the myInt property. Now
when I do this:
self.myInt = 123;
when initialising MyObject, the value shows up in the text field.
But if I do this instead:
myInt = 123;
the textfield just shows '0'. What's happening here?
