iOS 13 is the thirteenth major release of the iOS mobile operating system developed by Apple Inc., being the successor to iOS 12. It was announced at the company's Worldwide Developers Conference on June 3, 2019, and is scheduled to be released in the fall of 2019.
Introduction and initial release
iOS and iPadOS 13 were introduced by software engineering director Craig Federighi at the Apple Worldwide Developers Conference keynote address on June 3, 2019. The first beta was made available to registered developers following the keynote. As of mid-June the second beta is available to registered developers with the first public beta to follow at the beginning of July. The public release of iOS and iPadOS 13 is expected to be made available in the fall of 2019.
The QuickType virtual keyboard now features QuickPath, allowing the user to swipe their finger across the keyboard to complete words and phrases. This functionality was previously exclusively available via certain third-party keyboard applications such as SwiftKey or Gboard on Android.
Sign in with Apple
A new single sign-on implementation known as "Sign in with Apple" was implemented, allowing users to create accounts with third-party services with a minimal amount of information. Users have the option to generate a disposable email address for each site, improving privacy, anonymity, and further reduces the amount of information that can be associated with a single email address. All iOS applications that support third-party login methods (such as Facebook and Google login methods) must support the "Sign in with Apple" system, and the iOS human interface guidelines recommend that developers place the "Sign in with Apple" option above other login methods.
Several improvements to performance in iOS 13 were implemented. Face ID on the iPhone X, XS / XS Max, and iPhone XR now unlocks the devices up to 30 percent faster than it does on iOS 12. App downloads will be up to 50 percent smaller due to a new format, and app updates will be up to 60 percent smaller.
iOS 13 adds support for Audio sharing with AirPods.
Redesigned and rebuilt from the ground up with the ability to suggest when a reminder should be delivered to the user, and the ability to tag contacts so that references to reminders can be surfaced elsewhere (such as in Messages).

Using on-device machine learning, Photos curates the entire library to highlight the best images, automatically hiding clutter and similar photos to showcase significant events from the past day, month or year. Photos and videos are intelligently organized, making it easier to browse, discover and relive favorite memories, with auto play videos to bring the library to life. Photo editing is more comprehensive and intuitive with new tools that are easier to apply, adjust and review at a glance. With just a swipe, effects can be increased or decreased to create the perfect look, providing photographers with more creative possibilities and control over their images. And in iOS 13, most photo editing tools are now available for video editing, making it possible to rotate, crop or apply filters right within the Photos app.
iOS 13 drops support for several devices, including all devices with an Apple A8 chip or earlier, and devices with only 1 GB of RAM. This also marks the first time any 64-bit devices were dropped. Devices no longer supported by iOS 13 include the iPhone 5S, iPhone 6 / 6 Plus, and the sixth-generation iPod touch. Despite many rumors to the contrary, the iPhone SE is supported by iOS 13. 
To further differentiate features between iPhones and iPads, iOS 13 is now specific to the iPhone/iPod touch, and Apple has rebranded the tablet oriented platform with its own operating system, iPadOS.
