Sign in with Apple might be the most underrated feature to come out of the WWDC 2019 keynote. A lot of analysts, including Cult of Mac founder Leander Kahkney, think it’s a big shot at Facebook. The social media giant has become one of the iPhone-maker’s favorite companies to hate on recently, but Apple CEO Tim Cook says the new feature isn’t targeting Facebook.

The WWDC 2019 keynote came packed with exciting announcements.  As in past years, I ended up with four pages of drawings in my notebook. I sketched out the biggest new features coming to tvOS 13, iOS 13, macOS Catalina and watchOS 6. And then there’s the new Mac Pro and Pro Display XDR.

As seen in my first sketchnote, above, tvOS 13 adds multi-user support and support for Xbox One and PlayStation DualShock 4  game controllers for Apple Arcade. Meanwhile, watchOS 6 will bring an App Store directly to the Apple Watch, a new Noise app, and a new Cycle tracking app for women.

For a quick visual recap of the highlights  of the WWDC 2019 keynote, check out the rest of my sketchnotes below.

Update: Apple says “Sign in with Apple” will be mandatory for third-party apps that require sign-ins, according to these new App Store guidelines. That means apps that currently use Facebook or Google to sign in will also have to support “Sign in with Apple.”

“It will be required as an option for users in apps that support third-party sign-in when it is commercially available later this year,” the new guidelines say.

Apple is targeting Facebook with a new privacy feature in iOS 13 that privately logs users into third-party apps and services.

Called “Sign in with Apple,” it aims to replace popular cross-web login services like ones offered by Facebook and Google.

The new privacy feature prevents third-party apps and web services from tracking users via their logins. It creates private, disposable logins for every service or app.

Wow, iOS 13 is quite something. We got most of what we wanted, and a lot more. Proper USB support, an improved Files app, plus a radical new UI paradigm for the iPad. And what about that mouse support!

Let’s take a look at the main points. And over the coming weeks and months, we’ll be going extremely deep on everything that’s new in iOS 13.
