SAFARI TECHNOLOGY PREVIEW DOWNLOAD CODE
Since Apple has been a major part of both WebKit and LLVM, using LLVM as the backend to achieve greater optimization of JavaScript code made sense. B3 is the new compiler backend for WebKit's FTL JIT compiler which was introduced about a year ago with LLVM acting as the backend. At that time there was a great deal of info about the work that went into making LLVM, traditionally a production grade compiler for native applications, usable for compiling JavaScript on the fly within the constraints of something like a smartphone. I am personally not a web developer, and the fact that JavaScript is just now adopting more explicit class declarations on top of the existing function prototype based declarations comes as quite a surprise to me.Īnother key feature of the Safari Technology Preview is the new B3 Just-In-Time (JIT) JavaScript compiler. The first is that it has what they claim to be one of the most complete implementations of ECMAScript 6 (ES6), which in less precise but simpler terms means the latest version of JavaScript, as JavaScript was standardized as ECMAScript and now can be considered an implementation of the standard itself.ĮS6 comes with some key features for developers, including support for classes as part of the object oriented paradigm, iterators, and many new APIs. Since the target audience consists mainly of programmers building websites and web applications, it doesn't make sense to limit it to developers building native apps for iOS and OS X.Īpple is highlighting some key things that are new in the initial release of the Safari Technology Preview. One important thing to note about the Safari Technology Preview is that, while the app is available from Apple's developer site, you don't need to be a registered developer paying the yearly iOS and OS X publishing fee to access it. Having a separate application means that comparisons and regression testing between the current official version of Safari and one with a more up to date version of WebKit can be done easily.

This makes the list of changes and additions easily accessible with each update, and because the builds are signed by Apple there's full support for iCloud integration.

It's available from Apple's developer website, and updates will come every two weeks via the Mac App Store. What the preview consists of is an application separate from Safari that uses a more up to date version of WebKit than what the public version of Safari that comes with OS X uses. The Safari Technology Preview is Apple's attempt to address some of these problems, and make it easier for developers to keep track of what changes are being made, and to submit feedback or bug reports based on what they experience. It also disables features like iCloud integration for tabs, bookmarks, passwords, etc, as the builds are not signed by Apple. For one, it essentially made the version of Safari on a computer use the new nightly WebKit back end that was installed, which can lead to annoyances when trying to compare between the existing public release and the nightly build.

Distributing nightly builds for developers is a common practice for large software projects, but in the case of Safari and WebKit it was not ideal in many ways.
This allows developers to test and develop against new features being added to WebKit, which later make their way to Safari and other WebKit-based browsers as well.

Traditionally developers who want to use the latest improvements to WebKit have had to download WebKit nightly builds, which as their name implies, are builds that reflect the latest changes to the WebKit code base and are released on 24 hour intervals. Today it's widely employed in many browsers on many platforms, with Google and Opera formerly using it and now utilizing a fork of WebKit called Blink. WebKit was originally started as a project within Apple as a fork of KHTML, a layout engine developed by the KDE project. Safari is Apple's browser across all of their iOS and OS X devices, and the layout engine at its core is WebKit. Today Apple made an interesting announcement for developers regarding Safari.
