App design tip: Xcode 10 includes image data when copying XIB controls to the clipboard. This means you can easily copy/paste pixel-perfect  UI into your UX mockups.

Experiment in minimalist Swift, simple 3D world written in ~200 LOC, no 3D/gfx libraries, just some floats + cos/sin. Clearly feeling nostalgic for Spectre game that shipped on my '93  Performa. GitHub: github.com/matthewreagan/Sim…

Wrote a Swift app to play with & visualize Fourier series. Swift is fun for little proof-of-concepts like this

If you just Airdropped a bunch of photos from iOS to your Mac and need to quickly convert them, you can use `sips` (which supports HEIC). Ex. one-liner (converts HEIC -> JPEG):

I should add that this only appears to work for AppKit controls, not UIKit, unfortunately

Wrote a basic Perlin noise generator in Swift to experiment with procedurally generating organic textures in SpriteKit. (Fun to play with the math, vs. using GameplayKit.) gist.github.com/matthewreaga… #Swift #gamedev #SpriteKit

New blog post on SpriteKit shaders and geometry deformations. Demo code & video: sound-of-silence.com/?articl… #gamedev #spritekit #ios #macos

Demo of a simple technique for breaking apart 2D nodes in #SpriteKit for shatter or explosion effects. Video + code: sound-of-silence.com/?articl… #Swift #gamedev

Xcode tip: delete the same text across multiple lines by option-click-dragging. You'll get the ? cursor, but it will still function as a selection tool. #Swift #Xcode

Experimenting with procedurally-generated terrain + water in #Swift for game prototype idea. (Belated #screenshotsaturday) #gamedev

Bash script to generate all 2^n-sized images from an input, for draft #macOS app icons or general resizing: github.com/matthewreagan/Mac…

Enabled in production, but essentially a NOP without a custom environment variable switched on, allows QA/testers to catch

Friendly reminder: not all string comparison methods are equal. Be careful, especially with localized text. #Swift

Working on a SpriteKit node for Dust's UI to display game time + weather #gamedev #screenshotsaturday Dev blog: sound-of-silence.com/?articl…

Custom Xcode breakpoint sounds, available on GitHub + blost post on debugging with them: sound-of-silence.com/?articl…

If you need to branch conditionally between Mac/iOS, avoid TARGET_OS_MAC, it's 1 even for iOS (table: @gparker)

CALayer's linear minification filter can often look nearly identical to 'nearest'. If your layer is looking ugly, try kCAFilterTrilinear

Illogical, conflates design & eng.; equates any  product flaw as failure in design? I think author is either confused, or trolling /.02 nitter.gq/theatlantic/status/829…
