SwiftUI (Quick) Tap Gesture

SwiftUI Quick Tap Gesture

For games etc the tap gesture is useless as it has delay. This is slightly hacky but I suspect fine for most cases.

It would be pretty easy to include/pass the location too (another weakness of the built in tap gesture is that it doesn't give you this).

quick-tap.swift

import SwiftUI

// fuck it this should be fine-ish (as on main thread)?
fileprivate var lastStartPoint: CGPoint?

extension View {
  func quickTap(action: @escaping () -> Void) -> some View {
    gesture(DragGesture(minimumDistance: 0).onChanged { value in
      if value.startLocation == lastStartPoint {
        
      } else {
        lastStartPoint = value.startLocation
        action()
      }
    }.onEnded { value in
      lastStartPoint = nil
    })
  }
}
