Tested with iOS 18.1 and Xcode 16.1 beta and the issue still exists

still reproducible after updated to Xcode 16 beta 4

tested with iOS 17.1 beta and the issue still exists

Change the code to confirm that the issue affects TextField, but not Text. The code below change the Text color to red when 1 is entered, but not change the TextField color. struct ContentView: View { @State private var numberText = "" var color: Color { let result = (Int(numberText) ?? 0) <= 0 if result { return .black } return .red } var body: some View { VStack { TextField("Enter a number", text: $numberText) .font(.title) .foregroundStyle( color ) Text("Font color will turn red if number > 0") .foregroundStyle( color ) } .padding() } }

@Claude31 the print output as I expected, the the TextField color does not update on iOS 17 simulator. Here is the output for input 0, 1, A: numberText Int nil result = true numberText 0 Int Optional(0) result = true numberText Int nil result = true numberText 1 Int Optional(1) result = false numberText Int nil result = true numberText A Int nil result = true

My workaround: create our own unique key with title and author: @Model final class Book { @Attribute(.unique) var titleAndAuthor: String var title: String var author: String init(title: String, author: String) { self.title = title self.author = author titleAndAuthor = self.title + self.author } }

I tested define @Attribute(.unique) multiple times and seems not a correct solution: @Model final class Book { @Attribute(.unique) var title: String @Attribute(.unique) var author: String } I tried to insert books have some wried result: container.mainContext.insert(BooK(title: "book 1", author: "author 1")) try? container.mainContext.save() // 1 book inserted container.mainContext.insert(BooK(title: "book 1", author: "author 1")) try? container.mainContext.save() // 1 book inserted as expected container.mainContext.insert(BooK(title: "book 2", author: "author 1")) try? container.mainContext.save() // "book 2" replace "book 1", and 1 book is left.

I have a similar question also, for now I would create and UUID instead of complex key, e.g.: @Attribute(.unique) var identifier: UUID
