Swift Bindings won't work Xcode 6 Beta 5

Question

I\'m doing a simple test program using bindings in Swift on OSX. Having an NSTableView, NSArrayController and a model class I try to hook them up together, but without succe

Answer 1

Beta 5 requires you to explicitly set your properties as dynamic in order for KVO/bindings to work:

dynamic var firstName = "Brook"

See the Dynamic declaration modifier section of the release notes for more information.

The dynamic keyword enables KVO, proxying, and other advanced Cocoa features to work reliably with Swift declarations.
