What's New in Xcode 9
This year’s WWDC announcements focused on the exciting new SDKs, such as ARKit, and the changes to iOS 11. However, Apple has also made significant improvements to Xcode with Xcode 9. Not to be outshone by the other announcements, the new version of Xcode is a leap forward for coders. Developers are sure to be happy!
Included in this year’s improvements:
- updated support for Swift 4, including parallel support for Swift 4.0 and 3.2
- super-charged speed improvements to Xcode Project Navigator and Editor, from indexing to refactoring tools
- a completely rebuilt source code management (SCM) component, with seamless Git and GitHub integration
- ability to run multiple concurrent simulators, as well as wirelessly debug on physical devices such as the iPhone and Apple TV
- a new Main Thread Checker tool to ensure UIKit and AppKit thread compliance
- improved Interface Builder rendering of UI components.
Certainly this is a very exciting list of changes, so let’s go them one by one, starting with Swift 4.
