At Apple's developers' conference keynote in San Francisco, the company's senior vice president of software engineering, Craig Federighi, highlighted a number of new tools coming to Apple's iOS 9 update.

Some of these features include a native news aggregator (aptly called News ); a refreshed user interface for the more "proactive" digital voice assistant Siri, and split-screen capabilities for the iPad.

But Apple also quickly included a slide that listed 30 developer tools that will be available for iOS 9. While some of these features will appeal only to software professionals, others will have a direct impact on how consumers will experience their iOS devices after the update. Below are the features Apple briefly displayed during the keynote:

  • OCR accessory setup
  • Search extensibility
  • Audio unit extension
  • VPN plug-in extension
  • Swift 2
  • Map customization
  • Direct document
  • UI testing in Xcode
  • Notification actions

  • Motorized windows profile
  • Flyover and walk-through
  • New Health data types

One notable item on the list is "app thinning," which lets users download apps that are tailored to their iOS device. Because these apps are optimized, they should take up less memory and launch faster.

Another advancement to iOS 9 is the rollout of Swift 2, which is also listed above. According to CNET's Tim Stevens, as Apple's programming language for iOS and OS X, Swift 2 will have "more comprehensive error handling," and most significantly, will be available as an open-source platform. That means there will be even more apps coming to users as new developers take advantage of the language's support on multiple platforms.
