Property observers might not work the way you think they should when you have property wrappers. If you have a published property defined as:
Code Block swift| @Published |
| var myProperty: String |
The type of that property is not
String, it's
Published<Self.Output>.Publisher (or something like that) - when you do something like
myProperty = "A new value", the property wrapper is effectively intercepting the variable assignment, and updating its' internal representation. In other words, the value of
_myProperty.projectedValue changes, but the value of
myProperty does not - hence, your didSet observer is never called.
I'd call this expected behavior, but perhaps surprising if you're not familiar with how property wrappers work. You can, of course, subscribe to the publisher (which will give you willSet semantics), or you may be able to create an extension of Published to give you what you want
