How can I get the sidebar icon out of my sidebar and just like how Journal/Notes app have it?

It’s a catalyst app with a SceneDelegate :/

Anyone?

Just wrapped up an incredible two days partnering with Apple for Super Charge ‘25! Spoke to 1,600 students and ran four hands-on SwiftUI workshops.

Seeing their ‘Wait, I actually built this?!’ moments was pure magic!

Today’s widget really showed me that I’m the happiest when I’m playing football in the rain! (Hope my wife doesn’t see this post).

Pretty excited to attend this in Mumbai - I have been so out of touch with the android ecosystem. It’s about time I start meeting more people in tech in my own city!

Very appropriate Meta, very appropriate!
I always accidentally trigger this 🙃

Last week we did the largest “Today at Apple” event at a university. Involving product head for education & enterprise, Apple retail teams and WWDRs!

✅ 2 talks with live SwiftUI demo on stage

✅ 400 students making their first iOS app split across 4 workshops across 2 days

It ended on such a high!

Flight had to circle the skies because the visibility was below 100m for over 90mins! That’s a crazy smog over Delhi.

I can tolerate a lot of air pollution, but not sure I’m prepared for Delhi’s AQI! Taking off soon, will report back

Okay - wow!
I am now a visionOS expert, thank you!

My app Tasks is going to so beautiful on visionOS when polished further ❤️
