Hi Claude, This sounds encouraging. My current theory is that willSet/didSet works for @AppStorage var's in View's but not for @AppStorage var's in other types of objects (eg, in my case, a class) I will investigate this tomorrow morning, and report back with a more complete code snippet. thx :-)

Thanks @Claude31 This is likely what I'll have to do. The problem is that .onChange (I believe) is typically used in the body var of a View. my WordsManager is a class. Is it possible to use .onChange in something like my singleton class? (my current understanding is this is not possible.)

Thanks for the suggestion @ssmith_c . Unfortunately, I haven't been able to create an AppStorage var with a custom setter that the compiler likes. Definitely open to suggestions...

Hi @interferon , sadly didSet does not appear to be getting called on any of my AppStorage vars

Wonderful. Thanks very much for this very helpful answer :-)

I ended up doing a two step decode: decode to a [String: Localization] dictionary use the step 1 dictionary to create a [Language: Localization] dictionary

Hello gchiste, your assumption is correct. I was referring to a "Photo Editing Extension" I still do not see my extension when I follow the above steps, however I do see it when I follow these steps: run my new 'empty' PhotoEditingExtension target in an iOS simulator select photos as the app to run open a photo tap 'Edit' tap the ... button in the Edit view Following the above steps no a physical device I don't see my extension in the Options bottom sheet :-(
