Apple has started rolling out the fifth developer preview of its upcoming iOS 10 firmware upgrade. Developers and willing beta testers are now free to check out what the iOS 10 will be bringing to the table.

On Tuesday, the Cupertino-headquartered tech company released the iOS 10 beta 5 for iPhones and iPads, while it continues to polish the official update in time for its debut this fall.

Since this is already the fifth beta, most of the iOS 10 features have already been teased in the previous versions. The big difference is the improved smoothness of the new build compared to the buggy and unstable first four betas, according to TechCrunch

As previously revealed by previous versions, the iOS 10 will come with a new widgets panel, a new output icon, improved facial recognition in Photos, a new Lock screen sound and fresh content for Swift Playgrounds. 

Apple also fixed some issues with the previous versions, such as the problem with the Smart Battery Case when used with the iPhone 6s. Previously, the handset’s software panics when the battery-enhancing device is attached.

Improved implementations also mean better iOS interaction with Apple TV, App Store, Bluetooth and apps like iMessage and the Wallet applications. 

The most interesting aspect of the upcoming iOS 10 is  "Swift Playgrounds," which is basically a “how to code” class for kids disguised as a video game, as per The Verge

Previous betas have already leaked what this game is capable of, since it has coding lessons and challenges that are designed to teach users, especially kids, the rudiments of programming. 

The iOS 10 beta 5, which was rolled out along with the new watchOS 3, tvOS and macOS betas, gives a sneak peek into the many challenges users will have to deal with in order for them to master the fundamentals of computer science. Learn to Code part 1 and 2 lessons are also included in this new build. 

Apple’s fifth developer preview of the iOS 10 is now available to download over-the-air for developers and beta testers who have obtained the first four releases, MacRumors has learned.  

The Cupertino tech company is reportedly releasing iOS 10 alongside the iPhone 7, the iPad Air 3 and the iPad Mini 5 this fall.
