How do you make these? Complete graphical mockups or do you actually code the UI for some of these and let the OS render?

What were the biggest headaches? :) anything our team can do to help reduce these in future?

It's kinda sad our devices are all solid state with quiet fans. you don't really *feel* how the thing is working for you

Thanks Dan, I'll have someone take a look at this. FYI - We've been working recently to get the performance panel working on React Native DevTools. shipping soon-ish 😅 and plan to look at perf and profiling tools more closely next year.

this is btw, the main reason I HATE Apple events. everyone just talks the same, moves the same, very clearly reading from a script. BORING.

If you just "copy" his delivery style, it's just not going to be the same. be you. don't hesitate to show your personality.

Pretty cool to think how Apple itself reached out to the web technologies toolbox when they needed to ship something fast 🙃

And inside, a single NSLog();
Someone forgot to remove a debug print in the shipping binary! at some point this was a web app, running in a UIWebView... in fact Ken Kocienda and Richard Williamson mention this in their CHM interview www.youtube.com/watch?v=xImA...

Scroll all the way at the bottom of WeatherController and we find webView:runJavaScriptAlertPanelWithMessage:
If you've done any WebKit work you know what this is: One of the WKUIDelegate's methods! 👌👌👌 (developer.apple.com/documentatio...)

The shipped binary is just your regular Cocoa/ObjC MVC app. Some controllers, view and model objects. Nothing too interesting. BUT....

Another favourite is the original Weather.app, with a cool origin story - starting out as an iPhone optimized version of the weather dashboard widget from OS X >>>

If you look closely at the UITextViewLegacy methods, you'd see some references to styles and web objects. internally all the way up to iOS 7, the system was using WebKit for rendering! you'd set your styles using ObjC, that would turn to CSS behind the scenes. >>>

For a long while after shipping the iPhone SDK, there was a lot of duplication between the UIKit classes used by Apple (UITextViewLegacy, UITable for example) and the publicly facing ones (UITextView, UITableView) >>>

(I know I should probably close the x one, but so many people I care about are still there...)

Looks 🔥 we'd love to see a PR and see how we can get this working on all platforms, native too? :)

Pro tip - I never use notifications for any social media app. Nothing can ever happen on social media that I need to be notified of. I only see it if I choose to check it. Protects my peace nicely.

I'm on Giffgaff/O2 and rarely have issues with 5g. GPS on the other hand is pretty bad in zone 1.
