If the Phaser 3 game sprites are not displayed on iOS change the type in the index.js file to type: Phaser.CANVAS
const config = {
type: Phaser.CANVAS,
backgroundColor: '005500',
parent: "robbers-rummy",
width: window.innerWidth,
height: window.innerHeight,
scene: [
Game
]
};
In CANVAS mode Phaser cannot set the background color with this.cameras.main.backgroundColor or this.backgroundColor. Set the background color too in the index.js file as seen above.
