@chriseidhof Hey, big fan of your other books. If I buy the SwiftUI ebook now will I get the update when it’s ready?

[iOSDevUK Conference @IOSDEVUK]

No hurry though - early bird goes through to the end of June.
Before that, we will be publishing draft speakers lists.

@ChristianSelig I’m not sure, but anything off screen will be redrawn when it comes back on screen right? So will reevaluate that dynamic provider with the current traits?
I used theme colors with UIAppearance proxies too. Docs say to remove the view from the window and add it back.

[Greg Spiers @gspiers]

@ChristianSelig Oops, I see in the code sample you’ve done that. Only thing I can add is you can have a static theme var, and return any colour from the dynamic provider based on that theme. But the key for me was telling the UI to redraw.

[Greg Spiers @gspiers]

@ChristianSelig Check out the dynamic provider init method on UIColor. I made a theme system using it. You need to call setsNeedsDisplay on the window when the theme changes. But it works well. https://t.co/YzUl9SxJO9

@samskiter @xenadu02 Hey, I’ve seen the swizzling solutions. They didn’t work in my case, even flat opaque views would have one or two pixel differences around text. I’ve still not found a way to force the simulators to do CPU rendering. Let me know if you do find a way to get consistent snapshots.

[Greg Spiers @gspiers]

Does anyone know if it’s possible to disable Metal in the iOS Simulator on Catalina? We’re seeing each GPU produce slightly different rendering which means our snapshot tests are failing. Similar issue on the snapshot library: https://t.co/Qmw9nKMylm
Maybe @xenadu02 can help? 🤞

[Greg Spiers @gspiers]

@johnnie_tseng Hey, no problem, happy it helped. No change from Apple, the Feedback is still open.

[Swift Package Index @SwiftPackages]

How do the new M1 Pro and Max perform in real-world Xcode tests? We found out this week by compiling and running tests across a range of machines! https://t.co/RgtPTK6cG1

[Richard Dingwall @dingwallr]

Really proud to ship something we've been working on for a long time: US customers can now add linked bank accounts and create ACH payments from the @monzousa app! Will be enabled for everyone very shortly💸

[Greg Spiers @gspiers]

@radiantav Sounds like it won’t help in this case if you need exact offset. I guess there’s no way of getting access to the orthogonal scrollview without hacky solutions like traversing the view hierarchy. Let me know if you find a better way.

[Greg Spiers @gspiers]

@FloFi @radiantav This seems to be fixed in iOS 15 beta 1. Had a lab at WWDC with a UIKit engineer that helped me fix the new zIndex issue on the headers too. Feedback number here if you want to dupe: https://t.co/hqqMa0SQjX

[Greg Spiers @gspiers]

@radiantav It’s not perfect, but there is a visibleItemsInvalidatioHandler on the section that gets called. I used it to work around lack of delegate for orthogonal sections. Hope that helps

[Greg Spiers @gspiers]

If you enjoyed WWDC this year let Apple know. I’d love to see the online parts continue even if we eventually return to an in-person event.

[Greg Spiers @gspiers]

Going to my first one this evening 😀 I think there’s still time to register if you want to attend.

@MobileNotts @DevWithTheHair @mr_clark Thank you for organising this. Was nice to attend a meet-up again.
Great talks too 👏

Thank you everyone that contacted me. I’ve accepted a position I’m very excited about and will share the details shortly.

Monzo to lay off up to 120 employees as the 'economic situation' remains challenging https://t.co/T6Uefq6nrN by @sohear

[Greg Spiers @gspiers]

Looking to speak with people at other great companies to find a role suited to my skills. I can work in large projects, ship big changes safely (Monzo USA) and write architecture that scales to multiple dev teams (BBC Sounds).

[Greg Spiers @gspiers]

@fillito Dani! You were a great teammate. Our modularisation work is in safe hands, I can’t wait to hear about all the improvements it unlocks and where you take it next. Keep doing amazing things

[Greg Spiers @gspiers]

Today is my last day at Monzo 😢 I’ll really miss all the people, I’ve learned so much from my coworkers. It’s been great working on and shipping some amazing features.
