How to detect device name in Safari on iOS 13 while it doesn't show the correct user agent?

Question

After Apple's iOS 13 release, I realized window.navigator.userAgent in Safari on iPad iOS 13 is same as on MacOS. Something like this:

Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15) AppleWebKit/605.1.15 (KHTML, like Gecko) Version/13.0 Safari/605.1.15

As you see, it's a wrong user-agent for iPad and there is no way to detect if the current device is an iDevice.

After an initial research, I found a workaround for it:

Go to Settings -> Safari -> Request Desktop Website -> All websites. You notice "All websites" is enabled by default. If you disable it and get window.navigator.userAgent the correct user agent is now displayed.

But I cannot ask each user to do this setting change for each device. So I tried to find another way and ended up by writing the following code which checks if it's Safari, macOS, and touch-screen then the device should be an apple mobile device, but I'm wondering is there any better suggestion/way to detect the correct device name in Safari iOS 13?

detectOs = function(){
   //returns OS name, like "mac"
};

//is Safari on an apple touch-screen device
isSafariInIdevice = function(){
   if (/Safari[\/\s](\d+\.\d+)/.test(windows.navigator.userAgent)) {
      return 'ontouchstart' in window && detectOs() === "mac";      
   }
   return false;
};

Indeed, while option change in Settings may be a good solution for the user, as a developer you can't rely on that. It is as weird as to ask the user to not to use dark mode cause your app doesn't support it instead of opt-out of it using plist.

As for me, the most simple way to detect iOS / iPad OS device now:

const isIOS = /iPad|iPhone|iPod/.test(navigator.platform) ||
  (navigator.platform === 'MacIntel' && navigator.maxTouchPoints > 1)

The first condition is old-fashioned and works with previous versions, while the second condition works for iPad OS 13 which now identifies itself as:

"Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15) AppleWebKit/605.1.15 (KHTML, like Gecko)"

which by all platform detectors I know is not detected (for now) neither as mobile nor desktop.

So since iPad OS now calls itself Macintosh, but real macs have no multi-touch support, this solution is ideal to detect iPad OS devices which are the only multi-touch "Macintosh" devices in existence.

P.S. Also, you may want to augment this checkup for IE exclusion from being detected as an iOS device

const isIOS = (/iPad|iPhone|iPod/.test(navigator.platform) ||
  (navigator.platform === 'MacIntel' && navigator.maxTouchPoints > 1)) &&
  !window.MSStream

Answer 2

const isIOS = !!(/iPad|iPhone|iPod/.test(navigator.platform)
  || (navigator.platform === "MacIntel" && typeof navigator.standalone !== "undefined"))

As an alternative to the accepted answer, I found you can use the navigator.standalone param. It's non-standard and used only on iOS Safari at present:

Navigator.standalone

Returns a boolean indicating whether the browser is running in standalone mode. Available on Apple's iOS Safari only.

When combined with navigator.platform === "MacIntel" iPad's are the only devices that define this property, therefore typeof navigator.standalone !== "undefined" filters out Macs running Safari (touchscreen or not).

     function mobileDetect() {


    var agent = window.navigator.userAgent;
    var d = document;
    var e = d.documentElement;
    var g = d.getElementsByTagName('body')[0];
    var deviceWidth = window.innerWidth || e.clientWidth || g.clientWidth;

    // Chrome
    IsChromeApp = window.chrome && chrome.app && chrome.app.runtime;

    // iPhone
    IsIPhone = agent.match(/iPhone/i) != null;

    // iPad up to IOS12
    IsIPad = (agent.match(/iPad/i) != null) || ((agent.match(/iPhone/i) != null) && (deviceWidth > 750)); // iPadPro when run with no launch screen can have error in userAgent reporting as an iPhone rather than an iPad. iPadPro width portrait 768, iPhone6 plus 414x736 but would probably always report 414 on app startup

    if (IsIPad) IsIPhone = false;

    // iPad from IOS13
    var macApp = agent.match(/Macintosh/i) != null;
    if (macApp) {
        // need to distinguish between Macbook and iPad
        var canvas = document.createElement("canvas");
        if (canvas != null) {
            var context = canvas.getContext("webgl") || canvas.getContext("experimental-webgl");
            if (context) {
                var info = context.getExtension("WEBGL_debug_renderer_info");
                if (info) {
                    var renderer = context.getParameter(info.UNMASKED_RENDERER_WEBGL);
                    if (renderer.indexOf("Apple") != -1) IsIPad = true;
                }
                ;
            }
            ;
        }
        ;
    }
    ;

    // IOS
    IsIOSApp = IsIPad || IsIPhone;

    // Android
    IsAndroid = agent.match(/Android/i) != null;
    IsAndroidPhone = IsAndroid && deviceWidth <= 960;
    IsAndroidTablet = IsAndroid && !IsAndroidPhone;



    message = ""


    if (IsIPhone) {

        message = "Device is IsIPhone"


    }
    else if (IsIPad) {

        message = "Device is ipad"

    } else if (IsAndroidTablet || IsAndroidPhone || IsAndroid) {

        message = "Device is Android"


    } else {

        message = "Device is Mac ||  Windows Desktop"

    }


    return {

        message: message,

        isTrue: IsIOSApp || IsAndroid || IsAndroidTablet || IsAndroidPhone

    }

}



const checkMobile = mobileDetect()

alert(checkMobile.message + "  =====>  " + checkMobile.isTrue)
