Checks which iOS version is running.

iOSVersion.js

// http://stackoverflow.com/a/14223920/339827
function iOSVersion() {
  var match = (navigator.appVersion).match(/OS (\d+)_(\d+)_?(\d+)?/),
		version = [
			parseInt(match[1], 10),
			parseInt(match[2], 10),
			parseInt(match[3] || 0, 10)
		];

	return parseFloat(version.join('.'));
}

Plus detect Microsoft Internet Explorer on a Windows Mobile...

function iOSVersion() {
  if(!window.MSStream){
    // There is some iOS in Windows Phone...
    // https://msdn.microsoft.com/en-us/library/hh869301(v=vs.85).aspx
    return false;
  }
  var match = (navigator.appVersion).match(/OS (\d+)_(\d+)_?(\d+)?/),
      version;

  if (match !== undefined && match !== null) {
    version = [
      parseInt(match[1], 10),
      parseInt(match[2], 10),
      parseInt(match[3] || 0, 10)
    ];
    return parseFloat(version.join('.'));
  }

  return false;
}

Hi @lennybacon, I'd suggest tweaking that to, if(window.MSStream), having just tested that code on iphone 5 s and it returns false.

function iOSVersion() {
  if(window.MSStream){
    // There is some iOS in Windows Phone...
    // https://msdn.microsoft.com/en-us/library/hh869301(v=vs.85).aspx
    return false;
  }
  var match = (navigator.appVersion).match(/OS (\d+)_(\d+)_?(\d+)?/),
      version;

  if (match !== undefined && match !== null) {
    version = [
      parseInt(match[1], 10),
      parseInt(match[2], 10),
      parseInt(match[3] || 0, 10)
    ];
    return parseFloat(version.join('.'));
  }

  return false;
}

match returns only array or null

can I use this to detect ios 12 version? will it work?
