Hope this helps: https://www.swiftbysundell.com/articles/connecting-async-await-with-other-swift-code/ You can use concurrency prior to macOS 12.0 because it is a language feature, but not the macOS 12's frameworks (macOS feature). If you want to mix code of <12.0 and >12.0, you can use the example of that article to build your own function constructor.

I’m currently shipping a production app using .tabViewBottomAccessory in SwiftUI (tested and stable on iOS 26.0). After testing on iOS 26.1, I’ve noticed that when the accessory view is conditionally hidden, the space it occupies remains visible — an empty gap appears right above the tab bar. This regression will negatively impact users once iOS 26.1 rolls out. FB20772048
