SwiftUI: Increase tap/drag area for user interaction

I had the same problem. Except I didn't want the expanded overlay to impact the rest of the layout. If you embed everything in a ZStack and put a rectangle before your interactive object, you can control the size of the gesture. Kind of like this:

Rectangle().frame(width: screen.width, height: 300).opacity(0.001)
                    .layoutPriority(-1)

Just needed to make sure to set the opacity to next to nothing so you can't see it, and the layout priority to -1 so it doesn't impact the view.

Add a .contentShape(Rectangle()) after the frame.

I'm sure there are several ways to accomplish this, but this is how i made a big button with the whole area tappable:

Button(action: { someAction() }, label: {
                Text("OK")
                .frame(minWidth: 200)
                .contentShape(Rectangle())
                .padding()
            })
                .background(Color.blue)
                .foregroundColor(.white)
                .cornerRadius(5.0)
