@vi4m W Poznaniu jeszcze przed pandemią słyszałem fantomowe głosy dziecka. Później dowiedziałem się że za ścianą było przedszkole. 😉

Pół tysiąca dni na home office było fajne, nie będę kłamał, ale jakbyście tworzyli grupę wsparcia to pamiętajcie o mnie:

@dgregor79 I have an unexpected pointer in the middle of a swift enum type metadata. A value witness table pointer comes first, then the unexpected pointer, then a kind, finally a nominal type descriptor. Should this happen at all? As far as I know kind should be right after VWT.

I will bury this iPod Touch 4 as a time capsule, so future generations could try to unlock it. (The message says “iPod is disabled, try again in 26 milion minutes”)

UPDATE: This setting could cause crashes when used in a SwiftUI app. I stopped using it in my apps. Also mind that this could change behavior or reflection-dependent stuff (e.g. type string interpolation).

You can fighting the global warming with one simple Xcode trick. 🌱 Not using Swift Metadata? Set `SWIFT_REFLECTION_METADATA_LEVEL = none` for Release configuration. Doing so could save megabytes on your binary size. 🗜

@pointum @steipete Hi, I also dropped the setting because of the SwiftUI. I forgot to mention that on Twitter 🤦🏻‍♂️ Do you guys think I should delete the mentioned tweet?

@steipete I used this with no problem for years. Then SwiftUI bit me. Turns out it relies on reflection, so binding stuff breaks without warning. Figured it out the hard way after public release of an app. 🥲

Is anyone using this in production? I worry that we might end up with some code that interpolates a string from an enum, and without metadata that will just give you an "unknown" + log warning. Hard to lint against that.

@vi4m Trzymam kciuki. 😃 Ja zamiast „zasoby ludzkie” mówię „osoby ludzkie”. Oczywiście nigdy bym nie użył zwrotu „zasoby ludzkie”, ale „osoby ludzkie” fajnie brzmi, więc tego używam. 😅

I gave a talk about Swift binary compatibility at Allegro Tech Live. It was entitled "Let’s decompile Swift ABI Stability". Why decompiling Swift while it's open sourced? Sometimes one assembly opcode is worth a thousand lines of code. 🤖 youtu.be/ubJurLCxAtw?t=… #SwiftLang
