p5.js version

2.1.1

Web browser and version

iOS 26

Operating system

iOS

Steps to reproduce this

2 Steps:

1. Open THIS SKETCH on Safari on iOS
2. Press any button

I have a keyPressed() function in the button class.

function screenInteract() {  
button.keyPressed(); 
} 

function mousePressed() {   
screenInteract(mouseX, mouseY); 
} 

function touchStarted() {
if (touches.length > 0) {
    screenInteract(touches[0].x, touches[0].y);
  }
  return false;
}

function touchEnded() {
if (touches.length > 0) {
    screenInteract(touches[0].x, touches[0].y);
  }
  return false;
}

This does work on Chrome on Android. Any help appreciated!

Start by opening the linked sketch with p5.js 2.1.1 in Safari on iOS and reproduce the button interaction. Trace the mousePressed(), touchStarted(), and touchEnded() handlers shown in the report, then verify that the same interaction works on iOS Safari as it does in Chrome on Android.
