Some spam/fraud robocaller managed to call the emergency phone in our building’s elevator and blasted the “we’re just calling blah blah renew your auto insurance” on repeat. Hilarious and also a bit annoying 😂
Discovery of the day: the more cores your Mac has, the slowest to compile Swift it will be. Can anyone explain why writing a wrapper that forces Swift to use 4 jobs (passing `-j4` to swiftc) makes our build 30% faster on a machine with 8 cores? 🤔 github.com/apple/swift/bl…

Please RT if you aren't new to tech but still get the "Imposter syndrome" amidst all your experience. Having people Realize their favorites/mentors/role model also go through that, helps a lot on their tech journey and personal development.
Useful tip if you record gifs in the simulator often: `defaults write com.apple.iphonesimulator ShowSingleTouches 1`
If you need your app to behave differently based on device traits, you can store a configuration plist as data in your asset catalog and set different property lists for different devices, amounts of memory, Metal version, etc. Use NSDataAsset to load.
Sooo `NSMutableDictionary` does not import with the Key and Value type hints in Swift 4. That caused a nice really hard to debug crash… I.e. this compiles fine foo: NSMutableDictionary<NSString *, id> foo[false] = true 😱 See the lines with breakpoints in the screenshot

Remember Sublime Text's multiple cursors? For the new refactoring engine, the Xcode team developed a simple implementation for testing, but kept it disabled: defaults write com.apple.dt.Xcode PegasusMultipleCursorsEnabled -bool true
Work 40-50 hours and delay it a bit more tbh. No need to let people suffer like that for it

Oh noes 😨 I think I’m in a “how many ads can humans take before they stop using our service” A/B cell on YouTube. Keep getting 8 ads for videos. Even for videos that are 10-15 minutes long. Pre-roll, mid-roll and post-roll 😭
Xcode 9.3 beta (out as of yesterday) includes Swift 4.1 in it. Higlights include recursive protocols and conditional conformances support (w/o runtime casts). Feedback about build times, source compat, Osize optimization mode welcome as well as any other. :)
I'm not sure what I want to do with it first, but I really want to try out @luna_language. It looks like magic! It also looks like what a programmer on a TV show would be programming in. luna-lang.org
