That’s all from us here; if you want this liveblog in a more easily digestible format, my colleague Samuel Gibbs has wrapped the morning’s event up in one lovely piece.

Apple may have had a good morning inside its conference centre, but outside the room, things went less well: the company’s stock is sliding on reports that the US department of justice is considering an investigation into alleged anticompetitive practices.

Before we close the liveblog, one last piece of late-breaking news from the iOS 13 website, of great import: the volume indicator is now being moved to the corner of the screen so that it doesn’t pop-over the video you’re watching and spoil everything.

Tim’s back on stage, thanking everyone, and giving (vague) release dates: A developer beta for the new OSs today, a public beta in July, and the final release in “fall”.

And that’s that!

More of the developer-focused launches: Swift is getting UI scripting support, with SwiftUI. The developers in the audience are VERY EXCITED about how much less code you need to write a UI compared to before. You can also see the preview update live when you edit the code, which is again VERY EXCITING to the audience.

We move into the really nerdy bit: new APIs for developers who work with AR or Apple’s programming language Swift.

Skip this if that makes no sense to you. If it does:

• RealityKit and RealityComposer let developers work with AR experiences even if they can’t handle graphics engines or low-level code.
• ARKit 3 now has automatic “people occlusion”, letting the developer know exactly where a person is and put things in front of or behind them.
• It also has built-in motion capture.

ARKit 3 gets demo’d onstage by (the Microsoft-owned) Mojang, creators of Minecraft, who show off the new Minecraft Earth. You can build a world, walk around inside it, and play with friends. It looks fun, though “it’s hard to believe that there’s nothing on the ground or around us on the stage” has to win the prize for least convincing line delivery of the event.

A big launch for developers: “Project Catalyst” lets developers “quickly and easily develop Mac apps from their iPad apps”. “This means one development team for the first time can build a single app that can span all the way from iPhone to iPad to Mac.”

Mac apps that are coming at launch: the game Asphalt 9: Legends, Twitter and Atlassian’s Jira.

Federighi continues with the new features:

• Sidecar lets users use their iPads as a second screen for their Mac, or even as a graphics tablet, wired or wirelessly.
• Voice control lets users with motor impairments control their Mac and iOS devices entirely with their voice.
• “Find My” combines Find My iPhone with Find My Friends, and even works if the device is offline. How? Your sleeping macbook continues to send out a secure bluetooth beacon, that nearby iPhones – anyone’s nearby iPhone – can pick up, and report to Apple. It’s basically how hardware trackers like Tile works.
• Activation lock: just like on iPhones, you can set your Mac up so that it cannot be even wiped and reused without your password.
• Screen Time is coming to Mac from iOS, so that you can block Twitter from Safari on the desktop as well as on the go.

We get a price and release date! The Mac Pro will start at $5999, this autumn. (Expect that to be £5999). And the pro display will start at $4999, with an anti-glare version for $5999, and will also be available this autumn.

There’s also a new Apple Pro display. It’s HDR enabled. It has a cheesegrater back, just like the new Mac Pro. It has a 6K resolution and a 32” panel. It looks a bit like an iMac.

Apple is launching it by comparing it to a $43,000 reference monitor, which is some interesting anchoring. Anything will look like good value when it’s compared to the price of a mid-sized car.

There’s a lot of specs coming for the Mac Pro: it has a 28 core Intel Xeon, with 300 watts of power, supporting 1.5TB of Ram, and 8 internal PCIe slots. It has built in ethernet, four Thunderbolt 3 slots, two USB-A slots and a 3.5mm headphone jack.

It also has a new built-in graphics module, the MPX, that lets users dock powerful AMD graphics cards in a… new fancy way. But they can also dock normal graphics cards in a normal way.

There’s also another card called Afterburner, which users can buy purely to speed up their video rendering and playback.

And it has wheels.

And again, we get the round-up of things that just missed the keynote:

Now for the accessory roundup!

Airpods: Siri can read messages as soon as they arrive and you can instantly respond. And if two people have airpods and iPhones, they can now share audio just by tapping phones together, and listen at the same time.

Homepod: Get home and put your phone near the homepod to hand off music or a phone call to the smart speaker. It’s also getting live radio for the first time via Tune-In. And the speaker can personalise responses based on who is speaking for messages, reminders, notes, music and more.

Carplay: You can now have music and maps visible at the same time. Siri is now a popover, with the screen remaining visible when the voice assistant is active.

Siri: Last year’s Shortcuts feature will get an upgrade, giving you suggested Siri shortcuts automatically. And Siri is getting an AI voice for the first time, ditching the old human recordings for good. It sounds better!

Camera and Photos are also getting some new features – simple video editing in Photos, a new depth-sensitive filter in the Camera, and a whole new way of browsing photos in the main app: Apple’s going to use machine learning to intelligently hide duplicates, and to select new thumbnails that reflect a given day, month or year.

(It will be interesting to see how good Apple is at selecting these photos without access to the huge personal data stores of Facebook or Google. You may just have told your phone your loved-ones’ birthdays, but can it easily tell a meaningful shot from a half-arsed selfie?)

iMessage users can now choose to share their name and memoji (the dead-eyed avatars that Apple introduced two years ago) with people when they text them for the first time. And memoji get yet more variations: make-up, accessories and a variety of haircuts and colours are added to the options.

If you don’t want to film yourself making odd faces, Apple’s now adding a sticker pack of your own personal memoji letting you send yourself in pre-made poses. (Like Bitmoji, if you’ve ever used that Snapchat feature before.) And those features are coming to any Apple device with an A9 chip or newer – iPhone 6 or later.

And Apple now takes the fight to Amazon and its Ring subsidiary, offering a new API for smart home security cameras. HomeKit Security Cameras will share footage with your Apple devices, in a way that means the manufacturer can’t watch the footage, even if they wanted to.

But not everything is about competition: a new feature for secure routers is being built with another Amazon subsidiary, Eero.

Craig Federighi returns, to hit Google and Facebook with a big stick labelled Privacy.

• Users will be able to select a new “just once” option for requests like location tracking.
• Apps which try to sneakily find out where you are using Bluetooth or Wifi now won’t be able to get that data.
• And Apple introduces a new federated login service, competing with “sign in with Google” and “sign in with Facebook”: “Sign in with Apple”. “Just tap it and you’re authenticated with FaceID, logged in with a new account without revealing any personal information… Some apps may want your name or even your email – you can choose to share your real email address, or you can choose to hide it, and we’ll create a unique random email address that forwards to your real address. And we give each app a new unique random address”

That last one is a big, big threat to the business model of not just Google and Facebook, but a whole host of companies that require all the personal information of their users to monetise their services.

Tim Cook turns to iOS, with a direct swipe at Google: 85% of iPhone users are using iOS 12, while just 10% of Android users are on Android 9. Ouch. And introuduces Craig Federighi to introduce iOS 13.

Fed says the new iOS is faster. How much faster? 30% faster to unlock with FaceID; 50% smaller app downloads; 60% smaller app updates; 2x faster at launching apps.

But the first big new feature gets introduced with a video of some jellyfish: it’s dark mode.

And there’s more – too much more for Apple to read out, or me to transcribe. Take a look at the feature wall:

Health and fitness on the Apple Watch gets a whole sub-keynote:

• Activity Trends is coming to the Activity app on the iPhone, showing Watch users how their recent activity habits compares with the past year.
• A new Noise app will use the watch’s microphone to warn you if you’re in a loud environment where your hearing health is under threat.
• And cycle tracking comes to the Apple Watch. “A simple, discreet way to visualise your menstrual cycle right on your wrist”. The feature is also being (re)launched in the Health app on iOS.

Moving quickly on to the Apple Watch, then. Cook introduces Kevin Lynch to run through the new features of watchOS 6:

• New watch faces! Some purely visual updates, others with a few more smarts, including a solar clock
• “Taptic chimes”: the watch will buzz your wrist on the hour. It will also, if you want to be hated, play audible birdsong on the hour.
• New apps: a calculator, voice memo, and audiobook apps. The calculator can automatically add a tip and split the bill.
• And a new App Store, just for the Apple Watch, letting you install Apps directly on your watch.
• The nerdy bit: The app store is necessary because app developers can now make apps that run fully on the watch for the first time. They’re also now allowed to stream audio directly from the internet, as well as access have longer access to sensors than previously.

Cook runs through the tvOS features himself:

• Multi-user support for tvOS, letting the company personalise recommendations to each member of the household.
• Support for the XBox One and PlayStation 4 controllers on Apple TV, letting users who already have game consoles in the house use their own controllers on the box.
• And… new screensavers filmed underwater.

Cook opens by running through the services that Apple already announced earlier this year: Apple News+, Apple TV+, Apple Arcade, and so on. Some of these won’t be arriving until “fall”, likely alongside iOS 13, so don’t expect much more on them today.

Other, that is, than a new trailer for a fun-looking alt-history series, For All Mankind, coming exclusively to Apple TV+. The show imagines a world where the space race never ended after a Soviet cosmonaut became the first man on the moon.

But really, that’s just a segue into the first item on the agenda: tvOS.

As ever, we open with some natty promos: first, a cute animation featuring a load of emojis scrolling across the screen (a reminder, perhaps, that the small icons are the single best thing Apple has to get people to update their iOS), and then a classy black-and-white video showing developers working on their apps deep into the night (a reminder that this is, after all, the worldwide developers’ conference). And then Tim Cook takes the stage, thanking “the millions of incredible Apple developers across the world”.

Hello and welcome to the Guardian’s liveblog of Apple’s Worldwide Developers’ Conference. We’ll be kicking off at 10am Pacific Time – that’s 6pm UK time, and 3am in New South Wales if you’re staying up for all the latest news.

If you want to watch along live, Apple is streaming the event on its website. Otherwise, stick around, and we’ll digest two hours of back-slapping, stat-crunching and buzzword-dropping into one easy feed.
