What’s New in Xcode 8 for a Swift App Development Company

Customer experience would be the key business differentiator in the coming years. Brands and their business decision-makers, customer service analysts, and scholars worldwide share this common opinion when exploring ways of gaining a competitive advantage in the marketplace. The same endeavor reflected Apple’s modus operandi in the concluding WWDC 2016, with the announcement of iOS 10, which is expected to hit the market by the year fall.

What's New in Xcode 8 for a Swift App Development Company 1

Apple plans to fuel its customer experience strategy and make a bigger impact in the market. But, undeniably, it will not materialize without the active support of every Swift app development company and their development teams. Let’s look at the prominent resources made available by the company in its latest IDE (Integrated Development Environment), i.e., Xcode 8.0 Beta, to favor the development of iOS 10-compatible apps.

Source Editor Extensions

Xcode 8 adds support for Xcode Source Editor Extensions. Application Extensions provide additional commands in the Xcode Editor menu. For example, the extensions can modify texts and select areas. Swift app developers may use the Xcode Source Editor Extension Target Template in the macOS Application Extensions section before starting any project.


Interface Builder

Migration to auto layout is easier with the built-in Interface Builder. No longer is a developer in need to generate implicit constraints for views without restrictions. They can also zoom in and zoom out the interface across iOS, tvOS, and watchOS and edit the coding. Xcode 8 offers a completely redesigned workflow for working with trait variations (for example, size classes) and favors designing UI for a real device size rather than intentionally using abstract rectangles. In addition, the canvas lets developers watch interactions between iOS views as they appear at runtime, including accurate compositing of UIVisualEffectView.

Runtime Sanitizers

Xcode renders a new Thread Sanitizer feature to help Swift developers with compiler instrumentation and runtime monitoring. This will help detect and eliminate data races and other concurrency bugs in Swift or Objective-C programs. It can also catch memory corruption errors triggered using types such as UnsafeMutablePointer.

Static Analyzer

It helps in checking nullability violations at both aggressive and less aggressive levels. The more aggressive group examines nullability violations in all calls. It stays active by default for new projects. The less aggressive level checks for nullability violations in calls to project headers. However, it fails to do so with system headers.


Xcode Playgrounds aimed at macOS will now run with open-source Swift toolchains from However, Playgrounds targeting iOS or tvOS will rely on the Xcode 8.0 toolchain. The video tag associated with Playgrounds will also render support to remote URLs. I hope this latest IDE, in association with the powerful Swift 3.0 language, will help Swift app development companies and their developers to build quality apps matching the needs of their clients. Undeniably, the focus must not dilute the comfort and convenience of end-users, as Apple will not take any hit on that front. Swift 3.0 is the latest programming language made available by Apple.
