Reply to UIDevice: Main actor-isolated class property 'current' can not be referenced from a non-isolated context
Thank you, @Frameworks Engineer! In my case your comment helped me a lot. In my app I need to differentiate an iPhone device from other devices like iPad, Mac, etc. because on iPhone I must not select by default first element in my Navigation List, but I must do this on other devices. Initially I was checking like this: if !UIDevice.current.model.starts(with: "iPhone") { ... } but it showed me this warning "Main actor-isolated class property 'current' can not be referenced from a non-isolated context; this is an error in Swift 6" for such check within the (try? await ...) block. I was curious why, but now I understand, it's because UIDevice is only supported on the main thread. So, now I'm getting the value at once in the beginning: private let device = UIDevice.current.model and then just check the device in other places: if !device.starts(with: "iPhone") { ... }

Reply to How to add placeholder text to TextEditor in SwiftUI?
Here is a simple solution that works for me: VStack (alignment: .leading) { ZStack(alignment: .leading) { TextEditor(text: $comment) .frame(minHeight: 50) Text("Comment") .frame(width: 100, alignment: .leading) .foregroundColor(Color(.systemGray2)) .padding(.top, -22) .padding(.leading, 5) .opacity(self.comment == "" ? 100 : 0) } } It works rven if a user clicks/taps on the TextEditor, enters nothing, and then clicks/taps outside of the TextEdit.
