@State changes in Xcode 27 are causing variable definitions spanning multiple lines to produce unexpected compiler errors.

On Xcode 27, the compiler incorrectly errors when a @State variable definition is placed on multiple lines. The code compiles without any issues on Xcode 26 and is valid Swift. The issue is fixed if the var definition is placed on a single line.

The following code produces issues:

 @State
 internal
 var bodyText = "Hi"

However, the code below works:

@State internal var bodyText = "Hi"

The issue is reproducible in any new project with a simple view:

import SwiftUI
import Playgrounds

@main struct MyApp: App {
    var body: some Scene {
        WindowGroup {
            ContentView()
        }
    }
}

struct ContentView: View {
    @State
    internal
    var bodyText = "Hi"
    
    var body: some View {
        Text(bodyText)
            .padding()
    }
}

#Preview {
    ContentView()
}

The expected behavior is for valid Swift code to not trigger compiler error.
