@Neuromancer88 @centralcomputer Thanks for posting, stopped by and got one too 😁

@Neuromancer88 @centralcomputer oh I thought Nitro+ was available only in a bundle! Did you get one, or were they standalone in stock?

I stopped at @centralcomputer on my way to work just to get some thermal paste but managed to snag a #radeon 9070 XT! I was shocked to see GPUs in stock.

@centralcomputer ah so close! I wish this was for Nitro or at least Pure

We have another raffle for the AMD RX 9070 XT GPUs! 50x of the Sapphire Pulse RX 9070 XT GPUs and one could be yours! For full details and rules, visit our webpage! centralcomputer.com/rx9000 #9070XT #Sapphire #Raffle

📣Instruments in Xcode 16.3 Beta 2 contains a brand new tool for analyzing CPU workloads: Processor Trace. It uses hardware execution tracing to accurately reconstruct program execution and is available on M4 and all iPhone 16 devices. Learn more on developer.apple.com/documentation/…

Want to build cool stuff and don't mind working with me? Check this out 🙃 (says Cupertino-only but London's fine too!) jobs.apple.com/en-us/details/…

Only a few more hours left🤩 #AppleEvent

@maxdesiatov Congrats and welcome!

Crossed a few items off my bucket list these past few weeks. I had a blast visiting California and meeting teammates in person 🇺🇸 

@Plorkyeran That’s great! There are a few different improvements, so could be the combination too. Thanks for sharing.

@_dmcyk I'm actually seeing a bigger perf improvement than that. One of our executables dropped from ~700ms with beta 2 to ~300ms with beta 3. Must've been spending an abnormally large proportion of time in the thing you improved?

Xcode 14 beta 3 is out with some more performance improvements in ld64. Even up to 1.5x faster linking in some projects compared to the previous betas 🚀

Only a year ago I’ve attended WWDC labs, and this year I had the opportunity to host some myself 🎉 It’s been really fun, thank you to everyone who attended! P.S. You can still signup for tomorrow’s session ;) developer.apple.com/wwdc22/110716 #WWDC22

Don't miss the #distributed #actors #WWDC22 session on Wednesday! With the Distributed module, you can build distributed actor systems and bring your actor based to different processes: devices, or nodes in a cluster. developer.apple.com/videos/play/ww… There's a special guest appearance!

I am very happy that we can finally discuss page in linking. This has been a feature we have been working towards for years, and is built on the earlier efforts we made improving the binary format and making dyld pre-calculate and cache results.

This release is also the first I’ve contributed to and I’m very excited it’s out now! Do let us know how the build and launch performance changed for your app in Xcode 14 and iOS 16 🙂

Session about build and launch times is now online! Watch Nick dive into static and dynamic linking, share some tips to optimize your dev workflow and app performance, and learn more about improvements we’ve made. developer.apple.com/videos/play/ww…

We have lots of performance improvements in static & dynamic linking this year! #WWDC22

The team is growing, come join us! 👋

@Melvin_tan @Guardsquare Thanks Melvin, it's been my pleasure!

@_dmcyk @Guardsquare Great to have known you thru the iOS Conf and GuardSquare! All the best is your next journey!

Today was my last day at @Guardsquare. I had a blast being part of the team. Great people, great culture and extraordinary technical learning opportunities. I’m very grateful, and can definitely recommend it! Excited to share soon what will be next for me 🙂

@JDevlieghere Likewise! 👋

Time for some big news. I’ve joined the linker team at Apple and today was my first day! It’s a dream come true and I’m very excited about this role! 🤩🍎
