This is a Cocoa question, not a Swift question; a better place to ask is
Apple’s cocoa-dev mailing list at http://lists.apple.com, or Apple’s developer
forums.
(The quick answer is that NSTextField’s ‘value’ binding is by default an
NSString, not an NSNumber. If you want it to be an NSNumber, you’ll need to
attach a numeric NSFormatter to the text field. If you have further questions
about this, send them to me off-list since this is an off-topic thread.)
