The issue of the TextField being hidden behind the keyboard can be resolved by using .safeAreaInset(edge: .bottom) to place the input bar above the keyboard. Here’s a complete example that demonstrates how to achieve this in SwiftUI:

struct ChatView: View {
    @State private var typedText: String = ""

    var body: some View {
        ScrollViewReader { scrollProxy in
            ScrollView {
                VStack(spacing: 8) {
                    ForEach(0..<20, id: \.self) { index in
                        Text("Message \(index)")
                            .frame(maxWidth: .infinity, alignment: .leading)
                    }
                }
                .padding()
            }
            .safeAreaInset(edge: .bottom) {
                inputBar
            }
        }
    }

    var inputBar: some View {
        VStack(spacing: 0) {
            Divider()
            HStack {
                TextField("Start typing here...", text: $typedText)
                    .textFieldStyle(RoundedBorderTextFieldStyle())
            }
            .padding()
            .background(Color(UIColor.systemBackground))
        }
    }
}

Using .safeAreaInset(edge: .bottom) ensures the TextField is always displayed above the keyboard, respecting the safe area. This approach works reliably in iOS 15 and later.
