Apple today seeded the second betas of iOS 13 and iPadOS to developers for testing purposes, two weeks after first unveiling the new updates at the Worldwide Developers Conference.

Registered developers will need to download the profile for the iOS 13 and iPadOS betas from Apple's Developer Center. Beta 2 can be downloaded over the air after the profile has been installed and the iPhone or iPad has been restarted.

Apple in 2019 split iOS 13 and iPadOS into two separate updates, one designed for ‌iPhone‌ and one designed for ‌iPad‌. iPadOS is identical to iOS 13 in almost every way, though there are some iPad-specific features such as improved Apple Pencil support. For the most part, though, the two operating systems share the same features.

iOS 13 is a huge update with a long list of new features. There's a new systemwide Dark Mode that changes the entire look of the operating system from light to dark, from system elements to apps.

Apple overhauled the Photos app, introducing a new ‌Photos‌ tab that curates your entire ‌Photos‌ library and shows you a selection of highlights organized by day, month, or year, and there are revamped Photo editing tools. For the first time, you can edit video right in the ‌Photos‌ app, cropping, rotating, applying filters, and adjusting lighting and color. There's a new High-Key Mono lighting effect, and for Portrait Lighting in general, intensity can be adjusted.

There's a less obtrusive volume HUD, a new Find My app that combines ‌Find My‌ ‌iPhone‌ and ‌Find My‌ Friends and lets you track your devices even with they don't have an LTE or WiFi connection.

A Sign In with Apple feature gives you a convenient and data safe way to sign into apps and websites, providing an alternative to Facebook and Google sign in options. Apple's even able to generate single-use randomized email addresses so you don't have to give your real info to apps and websites. Maps has a new street-level "Look Around" mode and a Collections feature for making lists of places, Reminders has been entirely overhauled to make it more functional, there's a profile feature in Messages along with new Memoji and Animoji stickers, and Siri has a new voice. CarPlay in iOS 13 has been overhauled with a new look, multiple sets of AirPods can be connected to the same phone so you can share music, ‌Siri‌ on HomePod can detect multiple voices for multi-user support, and ‌HomePod‌ also supports Handoff. There are a ton of additional new features and changes coming in iOS 13, and for a full rundown of what you can expect, you should check out our iOS 13 roundup.

The beta testing period will allow Apple to work out bugs ahead of the release of iOS 13 and iPadOS, and it will let developers build iOS 13 and iPadOS features into their apps ahead of a public release coming this fall.

While the betas are limited to developers at the current time, Apple plans to make a public beta available in July.

Update: All of the new features in the second beta are listed in our What's New in iOS 13 Beta 2 article.
