Floating Action Button in SwiftUI

To create a floating button in SwiftUI, you can use a Button with a custom background and a fixed position within a ZStack. Here is an example of how you might do this:

struct FloatingButton: View {
    let action: () -> Void
    let icon: String

    var body: some View {
        VStack {
            Spacer()
            HStack {
                Spacer()
                Button(action: action) {
                    Image(systemName: icon)
                        .font(.system(size: 25))
                        .foregroundColor(.white)
                }
                .frame(width: 60, height: 60)
                .background(Color.red)
                .cornerRadius(30)
                .shadow(radius: 10)
                .offset(x: -25, y: 10)
            }
        }
    }
}

This creates a circular button with a red background, a white icon, and a drop shadow. The button’s action is specified by the action closure, and the icon is specified by the icon string.

To use this button in your code, you would need to create a closure that performs the desired action when the button is tapped, and pass it to the action property of the FloatingButton. You would also need to specify the icon to display on the button using the icon property.

For example:

struct FloatingButton: View {
    let action: () -> Void
    let icon: String

    var body: some View {
        VStack {
            Spacer()
            HStack {
                Spacer()
                Button(action: action) {
                    Image(systemName: icon)
                        .font(.system(size: 25))
                        .foregroundColor(.white)
                }
                .frame(width: 60, height: 60)
                .background(Color.red)
                .cornerRadius(30)
                .shadow(radius: 10)
                .offset(x: -25, y: 10)
            }
        }
    }
}

struct ContentView: View {
    var body: some View {
        VStack {
            ZStack {
                // Other views go here...
                Text("This creates a circular button with a red background, a white icon, and a drop shadow. The button's action is specified by the action closure, and the icon is specified by the icon string.To use this button in your code, you would need to create a closure that performs the desired action when the button is tapped, and pass it to the action property of the FloatingButton. You would also need to specify the icon to display on the button using the icon property.")
                    .padding()

                FloatingButton(action: {
                    // Perform some action here...
                }, icon: "plus")
            }
        }
    }
}

This will create a floating button with a “plus” icon that is positioned in the bottom-right corner of the view. When the button is tapped, the closure provided as the action property will be called.
