WRT @NSHipster's regex post:
import Foundation
let cluedo = "🕵️♀️🔍"
// NOTE: 2 characters, or 6+2 = 8 UTF-16 code units
let r = cluedo.range(of: "......", options: .regularExpression)!
// NOTE: 6 (not 2 or 8) dots
print(cluedo[r])
// MYSTERY: prints "🕵️♀️🔍"
This compiler flag saves time:
-Xfrontend -warn-long-expression-type-checking=50
(Especially if you're using SIMD types in Swift.)
Making a simple physics system for a possible WordFoto update. 2000 disks, verlet integration, spatial hashing.
Is there a bug in SceneKit's physically based materials? Normals towards -z makes material darker when metalness is low, no matter orientation of obj or the lighting env. Details here: bitcycle.com/scenekit-issue/ cc @mnuages @warrenm
Face order of +/-Z is wrong.
Is this a documentation or implementation bug?
Camera is at +2 Z, looking towards -Z (as it does by default), lightingEnvironment and background is a texture from the documentation of SCNMaterial contents.
Question in forums: forums.developer.apple.com/t…
Are these AppleColorEmoji bounding rect sizes by design or mistake?
(This is compiled with a recent snapshot so the values are accurate decimal representations of the floating point values. Also, the sizes are the same for all emojis, not just the one in this example program.)
A closure is …
1. … a function that closes over (captures) one or more variables.
2. … any function.
