Apple Releases Xcode 9 With Swift 4 and iOS 11, watchOS 4, tvOS 11, and macOS High Sierra SDKs

by

Alongside the new iOS 11, watchOS 4, and tvOS 11 updates, Apple has released Xcode 9, the latest version of the Xcode Mac app that lets developers create apps for Mac, iPhone, iPad, Apple Watch, and Apple TV.

Xcode 9 introduces Swift 4 and all of the SDKs necessary to develop apps for iOS 11, watchOS 4, tvOS 11, and macOS High Sierra, including the new Core ML framework for machine learning and ARKit for augmented reality.

Xcode 9 includes a new structure-based editor with native Markdown support and faster navigation through code, plus it includes built-in refactoring that works across Swift, Objective-C, C, C++, Interface Builder, and more.

Faster search and wireless debugging for iOS and tvOS devices have been added, as have new debuggers for Metal. iOS playground templates now work in both Xcode and Swift Playgrounds, and Xcode server is built in, so there's no need to install macOS server.

There's a new source control navigator with integrated support for GitHub for better collaborative code management, and Simulator has been updated to behave more like a real device. It's also able to simulate multiple devices at once.

A full and extensive list of everything new in Xcode 9 is available from Apple's developer site, and an overview is also available on Apple's Xcode site. Many developers will already be familiar with the changes introduced as Xcode 9 has been in testing alongside iOS 11 and the other software updates since June.

Xcode can be downloaded from the Mac App Store for free. [Direct Link]

Looking forward to updates to the editor. I still badly want Vim controls, though.
