Detect if device is iOS

Question

I\'m wondering if it\'s possible to detect whether a browser is running on iOS, similar to how you can feature detect with Modernizr (although this is obviously device detec

Answer 1

Wow, a lot of longish tricky code here. Keep it simple, please!

This one is IMHO fast, save, and working well:

 iOS = /^iP/.test(navigator.platform);

 // or, more future-proof (in theory, probably not in practice):

 iOS = /^iP(hone|[ao]d)/.test(navigator.platform);

 // or, if you prefer readability:

 iOS = /^(iPhone|iPad|iPod)/.test(navigator.platform);

• It's fast because the regexp checks the ^starting position of the platform string first and stops if there is no "iP" (faster than searching the long UA string until the end anyway)
• It's safer than UA check (assuming navigator.platform is less likely faked)
• Detects iPhone / iPad Simulator

UPDATE: This doesn't cover iPad in desktop mode (and therefore default iPadOS 13).
That's fine for my usecases, if it's not for you, see Justin's and kikiwora's answers.
