Happy Labor Day!
FAANG software engineer tells how they vibe code at FAANG --- reddit. com/r/vibecoding/comments/1myakhd/how_we_vibe_code_at_a_faang/
vibe coding cured my impostor syndrome, here’s how:
My wife built an app*, and wants to promote on TikTok etc. I know there are folks posting things like "I make apps go viral!" Who do you actually trust? Email a firm offer** to [email protected] and I'll send it on. (* I fixed bugs! ** Talk in $ not "Let's have a call…")
that plot sounds familiar
Days since the last bug caused by `RxSwift.Disposable.deinit` not calling `dispose()`: 0. Days since writing thorough tests prevented me from merging buggy code into master: 0.
The Xcode 26 beta 5 extra documentation is a fantastic resource for humans too! It's a great summary of all the new features. I'll try the built-in Xcode assistant tomorrow, with all this it should be much better!
TFW when your code is sooo bad the compiler turns the M4 Max into an Intel MacBook… …I didn't know this computer had fans till now TBH.
Announcing sourcekit-bazel-bsp: iOS development in IDEs like Cursor / VSCode, for Bazel projects! It's in very early stages, but I'm already very excited about the potential this has for the iOS community! github.com/spotify/source… #iosdev #swiftlang
Wrote a little bit about the worst place to have tech debt: in foundational/infrastructure code 😱 scottberrevoets.com/2025/07/02/fly…
Resetting the counter of days since last time a test catched a bug before it reached production 😎
Resetting the counter of days since an override of `==` caused a bug.
A little bit of fun to end the #WWDC25 week on: I went on the first 30 minutes of the Code Crawl event, and used my time to remake an effect from the early iPhone days!
What a wonderful week of WWDC! We are running a 30% sale for just a few more days, and then next week we conclude our “Modern Persistence” series by putting the finishing touches on our Reminders app with a couple of super complex queries. It can't be missed! Discount below 👇
