SwiftUI toolbar does not appear above keyboard.

[oscbyspro]

SwiftUI.TextField can add a toolbar above the keyboard as shown below.

view.toolbar {
    ToolbarItemGroup(placement: .keyboard) {
        Spacer()
        Button("Done") { /* action */ }
    }
}

This does not work on DiffableTextField, however. It should be fixed, if possible, otherwise an alternative should be offered.

This is one many properties that are not exposed by SwiftUI, so I'll have to make an inputAccessoryView alternative.

The view.toolbar modifier has a rather peculiar behavior. On each update its closure is called, but its views are only made on setup. A conditional view will only appear if its condition is true on setup, for example. But, if the toolbar contains a view like Text(String(describing: state)) and the state changes, the Text view will update its description. Hm.

If found some rough documentation on how it works.

https://developer.apple.com/documentation/swiftui/toolbaritemgroup/init(placement:content:)

But how to extract views is not public. Also, ToolbarContentBuilder

https://developer.apple.com/documentation/swiftui/toolbarcontentbuilder

This is the stupidest rabbit hole for something that “should just work”.

[oscbyspro]

Every option besides “pray that Apple exposes \.toolbar” seems bad. The least bad alternative besides that would probably be: something, something, UIHostingController.

Will wait on this one. I haven't yet thought of an idea that is not-so-bad enough to implement.
