Safari is a web browser created by Apple. Besides, the browser was established on the WebKit engine. This graphical web browse was first released for desktop, and it used Mac OS X Panther. With the release of the iPhone in 2007, the developers created a mobile version of this browser.
All Apple devices use Safari browser by default. However, there was a short stint between Windows devices and Safari from 2007 to 2012.
Safari browser has a reputation for being an extremely rapid web browser. Besides, it offers admirable levels of privacy to all its Apple users. That makes one a better choice for internet lovers.
Beyond speed and privacy, Safari boasts of:
- Powerful customizations – Safari has lots of customization options, including additional third-party extensions and a customizable start page. This current start page allows for customizing the background images and finetuning the browser window with features you like most, including Reading List, Siri Suggestions, Favorites, iCloud Tabs, and Privacy Report.
- Extensions – there are many extensions and functionalities on the Safari browser, making it versatile in exploring the web. Choose the extensions and functionalities to install from the App store.
What is Safari built on?
Safari is a popular browser that allows users to browse websites, open multiple sites, and bookmark favorites.
The web browser is built using the WebKit engine, making it one of the fast browsers that support the latest HTML 5 standard.
The Safari website was created using the open-source Konqueror web browser alongside its KHTML engine. But Apple then placed its own code in the Konqueror code place and added many improvements on KHTML, making WebKit a completely unique engine.
So, what’s the WebKit engine?
Developed by Apple, WebKit is a robust browser engine specifically for Safari web browser and all iOS web browsers. However, its versatility has seen it feature in BlackBerry Browser, the Tizen mobile operating systems, PlayStation consoles (from the PS3), and the Amazon Kindle e-book reader browsers.
WebKit uses the C++ API (application programming interface), which offers classes to display web content and implement browser features like managing a back-forward list, links when users click on them and driving the recently visited page history.
Sony, Google, Igalia, etc., have seen significant improvements in how WebKit works.
Forked WebCore by Google, released in 2013, is a WebKit component and will have significant application in google chromes and opera mini future versions under Blink’s name. WebKit has had many achievements, including being the first to support turning off Adobe Flash by default.
Currently, Safari on Mac OS is on version 11.1. this version comes with the latest features, such as an upgraded Intelligent Tracking Prevention (ITP). ITP is crucial in preventing specific websites from tracking the web pages you browse on other websites, and this process is typically referred to as cross-site tracking.
By contrast, on iOS, Safari shares its latest version, i.e., Safari 12.1, with the iOS version.
When you use the navigator object’s userAgent property, the browser sends you the user-agent header string. The user-agent series will contain information about your browser it details, where it will include specific keywords, which you need to test if they are present.
By contrast, if you want to check if a specific user-string is present, you can use the indexOf() method. This method typically returns the foremost occurrences of a specified user-string value within a string. If the value doesn’t appear in a string, you get -1.
If you want to access your browser’s user-agent string, you can access it using the navigator—userAgent property and store it in a variable. If you’re going to detect the existence of strings of browsers in user-agent, you’ll need to do it one by one.
Keep in mind that the navigator object is merely a window property. Therefore, you can only access it in two ways – window.navigator, and navigator.
Detecting version 2020 of Safari browser
First, you have to point out essential things before embarking on detecting the browser version, more precisely, the user-agent. For Safari Browser, the user-agent is Safari. The value “Safari” is usually passed to the indexOf() method, where it is detected in the user-agent string.
However, you require one additional check because the chrome browser user-agent also encompasses the Safari browser’s user-agent. If both user-agents of Safari and Chrome are present within the user-agent, it implies that that browser is chrome. Therefore, it will discard the value Safari Browser.
- Navigator object
This is an essential aspect of the browser detection process as it unveils important browser information, including userAgent. Ideally, it is a window property, and therefore, it comes in two ways – window.navigator, or the navigator.
Keep in mind that no public standard for navigator object exists. However, you’ll find it on all major web browsers.
Properties of the navigator object
Common properties include:
What it returns
Browser code name
the platform on which the browser is compiled
Browser engine name
the user-agent header, which browsers send to the server
Shows if a browser is online
Navigator Object Methods
- taintEnabled(): checks for data tainting
- javaEnabled(): determines whether or not the browser is Java enabled
- UserAgent property
This property will return the value of the user-agent header that the browser sends to the server. The value generated contains information regarding the version, name, and platform of the browser. Note that it’s a read-only property, and it is found on all major browsers. Its syntax is navigator.userAgent.
These four methods include:
- Extraction of information from the user agent and checking if it contains the name of the browser. For example, to check for Safari browser – if (navigator.userAgent.indexOf(“Safari”) != -1)
- Make use of a detection library like Bowser.
- Detecting the CSS vendor prefix, i.e., Checking if the browser supports Moz, WebKit, or MS.
- Browser duck typing – it involves checking for all the unique features of the browser.
The window.navigator is an object containing information about the visitor’s browser. Ideally, the window interface is a window that contains the DOM document. Remember that a document property points to the loaded DOM document in that specific window.
As earlier indicated, you can write the window.navigator object without the window prefix. Here are some basic examples:
The Window Object
Global variables represent the window object’s properties, while the Global functions represent methods of the window object. Additionally, the document object is normally a property of window object. These two strings are similar:
The size of the browser window is determined by two properties, which return the size in pixels. They are:
- window.innerHeight – showing the inner height of the browser’s window
- window.innerWidth -representing the inner width of your browser’s window.
- Go to the Settings app, and then scroll to choose Safari browser
- Within the Safari browse, there is the Advanced Menu icon at the bottom end; scroll to find it
This is easy now:
- Go to the setting icon and locate Safari
- Tap on the Safari Icon and locate the advanced menu to get access to these advanced settings
Therefore, if you want to establish the true name of a web browser quickly, you can use one of the following:
- navigator.userAgent properties
However, using the userAgent property will give you more reliable results than using the appName.
Note that device detection is very valuable to designers as it helps them optimize web pages for the type of device accessing it. Additionally, it offers a granular detailing level important to Programmatic Advertising. This makes it more effective when targeting real users.
Browsers like Safari are more specific to Apple devices, and they work exceptionally well, thanks to accurate designing.
Look, a web designer can optimize page layouts for a specific input method and screen sizes.
Besides, designers can improve performance by minimizing the data amount sent to devices on a slower internet connection.
The key things to consider while optimizing are the type of device, i.e., a tablet, a smartphone feature phone, or desktop. Additionally, input methods and screens’ physical dimensions matter.
Detecting iOS devices can be a little complex. But there are a number of methods to use to detect them. These include:
- User-Agent HTTP headers
- CPU stress testing
- WebGL API
- Screen dimensions and pixel density
- User-Agent – it identifies input methods and type of device, and it works hugely faster. However, it misses crucial screen info
- WebGL API – it covers close to 90 percent of cases when GPU is identifiable. If not, it returns based on screen size. Its limitation is it doesn’t give information until a second website request
- Stress Testing – good for granular model info
- Screen Dimensions – provides more data when used with user-agent
On the Home Screen, locate the Safari Icon.
Tap it to reveal the settings icon. Once you locate the settings, tap it, and scroll to find and select “Safari.”
THE Safari menu has lots of items – scroll until the foot of the list, and you’ll find “Advanced.” Select this option, an action that exposes you to advanced settings for the Safari browser.
This method involves using jQuery to detect the browser. While visiting websites, there is a lot of information that people can get, including IP address, Browser, Service Provider, etc. Most websites use Google Analytics, among other analytic programs, to track the number of visitors, the amount of time they spent on a website, and any other essential details. What’s more, advanced websites can track keyboard and mouse activities.
Retrieving the navigator object can only be done using a read-only window.navigator property. Though the navigator object features a lot of stuff, the .userAgent property is the most important. The .userAgent property is simply a string that has information about the browser OS.
Navigator object properties include:
- Navigator.connection: this is a Read-only aspect providing NetworkInformation, i.e., an object containing data about a device’s network connection.
- Navigator.cookieEnabled: ignoring a cookie returns false or else, true.
- Navigator.credentials: notifies users in case interesting events occur by returning the CredentialsContainer interface.
- Navigator.deviceMemory: returns device’s memory in GB.
Others include Navigator.locks, NavigatorLanguage.languages, Navigator.keyboard, NavigatorPlugins.javaEnabled and NavigatorConcurrentHardware.hardwareConcurrency.
In case you want to look for a string for a match, use the match() function, which is an inbuilt function.
That’s why browsers like Safari are robust interactive, and dynamic. This browser works the fastest on iOS but slightly lags on Mac.
Data from Safari doesn’t sync directly via the browser. Rather, this data is taken as part of the regular iCloud sync, available on OS X and iOS.
