Replying to @johnsundell
I did some experiments with UserDefaults(suiteName:) and potentially found a bug (state is not cleaned under some specific conditions in test target). @johnsundell @eldudi @merowing_ @norapsi anyone wants to bug hunt this? github.com/kprofic/UserDefau…

I'm migrating to a new galaxy called @Qualtrics. It's my first week and I think I will work here until I retire. It's gonna be fun! #qualtricslife #firstDay #firstWeek #ReactNative

Testing remote push notifications used to be a pain. With Xcode 11.4 you can just drag the payload into the simulator 👏

Sleep quality and stress exposition affect the code quality way more than any technique, process, technology or programming language that you believe in
One of my most controversial software opinions is that your sleep quality and stress level matter far, far more than the languages you use or the practices you follow. Nothing else comes close: not type systems, not TDD, not formal methods, not ANYTHING. Allow me to explain why.

Kind of impressed how the code reuse strategy was implemented here with @reactjs while embracing the platform specific differences in @reactnative at the same time
📺 My talk from @ChainReactConf, Successful Web & React Native Code Sharing Strategies, is up: youtu.be/KxSwRHi4lHk In which I'm discussing the strategy we've taken in @Nozbe 4 for sharing as much code as possible between all platforms we're targeting.

I just got this book by @Lethain and @stripepress. Excited to learn something about management 🤓
"I've come to view engineering management as a series of puzzles. This book is a collection of those puzzles which I have had the good fortune to struggle with and learn from." -@lethain An Elegant Puzzle is now available for pre-order. amzn.to/2GEx23Y

Since #kotlin compiler used http for dependencies it is vulnerable to MITM. It has also run into “Trusting Trust” issue as it uses itself to compile. Many technologies are affected (mostly around #jvm, @jetbrains) #infosec medium.com/bugbountywriteup/…
Really excited for the upcoming @CocoaHeadsKrk meetup that we host @talixocom together with @untitledknd. Can’t wait for @chriseidhof to speak about #SwiftUI meetup.com/CocoaHeads-Krakow…

„We’re in a transition, and transitions take years. But we’ve all just had a glimpse of the next 20 years.”
SwiftUI, the new declarative UI framework, thrilled to experiment with it!

part1: We were struggling with @mhelmecki to explain why only one of our frameworks behaves like we did some black magic with @_exported as here: davedelong.com/blog/2018/01/… by @davedelong even though we have CLANG_MODULES_AUTOLINK = NO which works fine for us in all other cases...

part2: The answer is: Extensions in Bar are still made visible to clients who import Foo, because the compiler doesn’t distinguish where extensions come from today. as stated on Swift Forum: forums.swift.org/t/exported-… and happily caught in the wild by @MichalCiuba!
1
part3: Lesson learned? Extensions aren't exported in the same way as other stuff in Cocoa Frameworks / Swift Modules. But beware - this isn't really a feature, seems like something that may be corrected in the future...
Solid topics picked by the editor. Like #AppleNewsPlus but without subscription 🤓

It’s funny, software developers often won’t listen to architects in their own organisations who haven’t written code for N years, yet they *will* listen to speakers at conferences who haven’t built or run real software systems for N years.
