I was looking for this answer and I remembered I came across this before.

The most reliable way to detect Safari on iOS in JavaScript is

if (window.outerWidth === 0) {
    // Code for Safari on iOS
} 

or 

if (window.outerHeight === 0) {
    // Code for Safari on iOS
} 

For some reason Safari on iOS returns 0 for window.outerHeight property and window.outerWidth property.

This is for all iPads and iPhones on all versions of iOS. Every other browser and device this property works normally.

Not sure if they intend to change this but for now it works well.
