@christianselig say Christian, where can I steal your Xcode color theme from? :D

christianselig, 3 months ago

@dinesharjani It's called One Dark! I don't quite remember where I got it from but it looks like a popular one at least

@christianselig can you if let the Binding using the unwrap initializer and only the show the Picker?

pakkito, 3 months ago

@christianselig I think you need to add @Bindable

layoutSubviews, 3 months ago

@christianselig FYI the .tag() modifier is superfluous here — it provides the same identity as the ForEach() already provides

christianselig, 3 months ago

@layoutSubviews If I drop it though, it no longer works :(

layoutSubviews, 3 months ago

@christianselig ah, right, because of the outer if let. My bad.

christianselig, 3 months ago

@layoutSubviews Oh all good, I'm appreciative that I now understand why it's needed :p

@christianselig @layoutSubviews Wait, I don’t understand! Please explain. 😊

@christianselig Are you aware of „Bindable“? You can also define a Bindable var inside your body callback to access stuff from the environment. https://developer.apple.com/documentation/swiftui/bindable

@maxmelzer How would I use it in this situation? I've tried a few different incantations to no avail

maxmelzer, 3 months ago

@christianselig Oooh, I think I figured it out. The problem is not about the Observable at all. The trick is that the type of your .tag must be exactly the type of your selection binding, including optionality. Try using „.tag(iceCream as String?)“, that should do the trick.

maxmelzer, 3 months ago

@christianselig Ah, sorry, I see you already got that info. Thanks for the small puzzle, though! :)

@christianselig I think this may be an issue of the type of the .tag being String instead of String?, which you can fix by doing .tag(Optional(iceCream)) or casting it to String?

christianselig, 3 months ago

@zachwaugh Aah that worked a charm, thank you!

@christianselig I think what you're looking for is @Bindable https://developer.apple.com/documentation/swiftui/bindable/

christianselig, 3 months ago

@bwebster I think I understand Bindable in the context of initializing a new object with the Bindable object, but how would I use it here?

bwebster, 3 months ago

@christianselig I think you should be able to just replace @State with @Bindable in that example? (not 100% sure as I've only used it a couple times myself)

christianselig, 3 months ago

@bwebster No dice :(
