Apple announced at WWDC 2014 news for users and developers on the App Store. With 1.2 million apps and more than 75 billion downloads, the store will become even better for everyone in the next semester.

Users will be able to find apps in batches for purchase, search based on trends and choose what to buy based on preview videos. For developers, the use of TestFlight, acquired at the beginning of the year, will allow the offer of test versions of applications for the evaluation of users.
On platforms, Apple will offer more than 4,000 new programming interfaces (APIs). IOS 8 brings extensibility features, so that applications can contractually adapt to content sharing panels, Safari, the standard photo editor and many other existing areas of the system.

In addition, features like the Notification Center have gained extensibility interfaces, allowing the writing of widgets that add contextual information from the web in a convenient way for reading.
Finally, we can also install third-party keyboards.

On iPhones 5s (and future devices that feature the Touch ID sensor), developers can access the authentication system via a digital reader that Apple launched last year.

For home accessories, Apple expanded the solution development interfaces for existing products and created HomeKit, a set of technologies around a single communication protocol created with the support of home automation companies. With it, devices running iOS can control systems such as automatic locks, thermostats and other products that are beginning to be used in homes around the world.

ICloud technologies for data storage have also been improved and now include authentication, database, content management for free use by developers.

For iPhones and iPads based on the A7 processor (and future Apple chips), the company has developed a new 3D graphics system for games. Games for iOS 8 can now be developed with direct access to the graphics processor, resulting in greater ease of development and performance β up to ten times faster than current OpenGL implementations in use on Android and iOS 7 itself.
Speaking directly of code, Apple has also created a new, modern, C-based programming language called Swift, it does not depend on many of the common development complexities and yet allows native access to iOS and OS features. X.

In addition to being easier to master (at least in theory, of course), it is also very fast and dynamic, enabling a new workflow in Xcode where the results of a development can be followed in real time on the interface. Apple will accept applications for iOS 8 and OS X Yosemite written in Swift later this year, and as of today any developer can have access to the resources needed for learning.
