Recreating the Xcode style value input

clicking and dragging: use a .gesture modifier on a view

click to enter a number: that's the behavior of a TextField

change cursor on hover: onContinuourHover and the methods on NSCursor should get you started

Step1 : Create A SwiftUI View

step2 : Use Gesture And Gesture state property I hope You Know How Too Add

this is the way -->

`struct CounterView: View { @GestureState private var isDetectingLongPress = false

var body: some View {
    let press = LongPressGesture(minimumDuration: 1)
        .updating($isDetectingLongPress) { currentState, gestureState, transaction in
            gestureState = currentState
        }
    
    return Circle()
        .fill(isDetectingLongPress ? Color.yellow : Color.green)
        .frame(width: 100, height: 100, alignment: .center)
        .gesture(press)
}

} this is example from [https://developer.apple.com/documentation/swiftui/adding-interactivity-with-gestures) just you can go through this

step3: You can gesture for scrubbing like you can use drag gesture

    @State private var isDragging = false


    var drag: some Gesture {
        DragGesture()
            .onChanged { _ in self.isDragging = true }
            .onEnded { _ in self.isDragging = false }
    }


    var body: some View {
        Circle()
            .fill(self.isDragging ? Color.red : Color.blue)
            .frame(width: 100, height: 100, alignment: .center)
            .gesture(drag)
    }
}

this is way to add gesture I hope you find it beneficial mate .

Step4: Then You Create Custom Field

var body: some View {
    TextField(
        "User name (email address)",
        text: $username
    )

This Is the Way You Can Add Custom Text Field for That You Have To Use @State As I Have Given In code Like It Depends What You Want To Name Its Depend On you

Step 5 : Add Cursor Modification Step 6: Then .onReceive modifier in SwiftUI allows you to listen to changes in a publisher and react to those changes. In the context of your Xcode-style value input field, you can use .onReceive to handle keyboard input for the text field and ensure that it responds to numeric input, updating the value accordingly.

struct XcodeStyleValueField: View {
    // State to keep track of the value displayed in the field
    @State private var value: Double = 0
    
    // State to manage whether the field is focused
    @State private var isFocused: Bool = false
    
    // Gesture state to track if the user is scrubbing (dragging) the field
    @GestureState private var scrubbing: Bool = false
    
    var body: some View {
        TextField("", value: $value, format: "%.2f")
            .textFieldStyle(.roundedBorder) // Apply a rounded border style to the text field
            .focused($isFocused) // Bind the focus state of the text field
            
            // Gesture to enable scrubbing (dragging) functionality
            .gesture(
                DragGesture(minimumDistance: 0)
                    .updating($scrubbing) { value, state, _ in
                        state = true
                    }
                    .onChanged { value in
                        if isFocused {
                            // Update the value while scrubbing
                            self.value += Double(value.translation.width) / 10
                        }
                    }
            )
            
            // Change cursor style based on focus state
            .cursor(isFocused ? .resizeLeftRight : .arrowCursor)
            
            // Toggle focus state when the field is tapped
            .onTapGesture {
                isFocused.toggle()
            }
    }
}

struct ContentView: View {
    var body: some View {
        VStack {
            Spacer()
            XcodeStyleValueField() // Use the custom value field
            Spacer()
        }
    }
}

@main
struct MyApp: App {
    var body: some Scene {
        WindowGroup {
            ContentView() // Set the main content view
        }
    }
}
