iOS 13 Beta


iOS 13 introduces a bold new look, major updates to the apps you use every day, new ways to help you protect your privacy, and improvements across the entire system that make your iPhone even faster and more delightful to use.


Apps will launch up to 2x faster than before and be smaller in download size.

Here’s the list of new features.

Joanna Stern:

You will FINALLY able to select a WiFi network in Control Center on iOS 13. How was this not 30 minutes of today’s presentation?!

Ryan Jones:

New title bar size and buttons! Less vertical space waste.

Eli Schiff:

Thread of changes in iOS elements:

Ryan Jones:

Automatic What’s New screens!!!

Ryan Jones:

And automatic ask for feedback.

Tanner Bennett:

This notification appears when you first join a hotspot.

This is the sort of power-user feature iOS needs more of. Bravo!


WebKit on iOS has always been the same engine as macOS. It was just significantly constrained due to the technical limitations of early iPhones. In iOS 13 we have removed many of these old limitations.

Dave Mark:

iOS 13 Apple Maps added traffic lights and stop signs. Apple Maps is getting steadily better.

Pierre Habouzit:

For people curious about this up to 2x app launch win, here is an overview straight from Craig’s mouth (for about 2-3 minutes at the 1:04 mark)

It sounds like the FairPlay DRM that prevents you from installing apps not signed by Apple has been slowing down app launching for all these years.

Federico Viticci:

No more URL schemes, no more clipboard hacks – all done natively and securely.

And the Shortcuts editor is much easier to use thanks to new pickers and natural language-style syntax. ❤

Steve Troughton-Smith:

One neat nugget of information in the File Management session: iOS apps can now be granted read/write access to an entire folder, rather than just a file (!!)

Juli Clover:

Apple in iOS 13 introduced a new “Optimized Battery Charging” feature, which is designed to extend the total battery life of your iOS device.

Found in the Battery section of Settings under “Battery Health,” the optional toggle learns from your personal habits and waits to finish charging all the way up until you need your iPhone.

Nick Heer:

I was blown away by the demo of Voice Control during the Platforms State of the Union presentation and, having had the opportunity to try it myself, it works pretty much as advertised. It’s shockingly good, almost to the extent that I was considering keeping it on so I could use my iPad while I’m cooking, for example, but I worry about its impact on battery life.

Juli Clover:

In the Phone section of the Settings app in iOS 13, there’s an interesting new toggle called “Silence Unknown Callers,” which appears to do exactly what the name suggests. With this feature enabled, calls received by people not in your contacts list seem to be sent straight to voicemail.

Update (2019-06-10): Bradley Chambers:

Apple announced data separation for BYOD devices. While we don’t know all of the details about how this will work, it does appear that Apple is moving to what I was asking for. Employees want to be able to make sure that IT departments can’t access their personal data, and IT departments want to ensure that their corporate data will be secure. I will have more to say on this as we learn more.

Meek Geek:

Oh look, Apple copied the Qnovo charging tech used by some Android flagships for years […] Hopefully iPhone batteries will last 2 years instead of being throttled after 1 year!

Matt Birchler:

First and foremost, the talk confirmed what I feared: there is no way to add arbitrary fonts you already own into iOS. They must be installed by apps downloaded from the App Store.

Geoff Hackworth:

I want to focus on immediately noticeable, and potentially breaking, changes to view controller presentations in iOS 13.

Update (2019-06-13): Michael Saji:

The explanation for why Apple took so long to implement USB storage for iOS: they had to rewrite the kernel storage driver to live in userspace. The most secure USB storage ever. Same for fonts.

Juli Clover:

In addition to these features that made it into Apple’s keynote event, there are dozens if not hundreds of smaller new changes and tweaks that are included in iOS 13. Below, we’ve rounded up a comprehensive list of new and notable “hidden” features in iOS 13.

Update (2019-06-18): Steven Aquino:

One cool tidbit about Voice Control: It uses the TrueDepth camera on iOS/iPadOS to tell if you’re looking at the computer. If someone walks over and you turn your head, Voice Control will stop listening until you go back to your computer.

Update (2019-06-19): John Gruber:

The new volume HUD in iOS 13 is delightful. Notice how it is physically aligned with the hardware volume buttons. This position and the animation make hardware and software feel as one.

Update (2019-07-05): Vinoth Ragunathan:

Stock apps load stupidly fast on iOS 13 beta 3.

Pierre Habouzit:

You’re welcome.


A lot of it is dyld3 and careful systematic runtime optimizations (I did a lot of obj-c work with @mikeash and others e.g.), and it wasn't just me, there was a whole team.

[…] iOS 13 Preview (my post) […]

[…] I will be interested to see whether the iPhone 6s and iPhone SE are supported by iOS 14. Given how well they currently perform, it seems like they could be. Launching apps is one of the slowest things, and that’s greatly improved in iOS 13. […]
