SwiftUI Meets Metal - Elevate Your UI Game
summary
Introduces using new iOS 17 view modifiers — ColorEffect, DistortionEffect, LayerEffect — to run Metal shaders from SwiftUI with far less glue code than a manual pipeline; shows concrete snippets (Metal Shading Language functions marked stitchable) that recolor a logo, convert images to black‑and‑white, draw an interactive “3D” dot field, pixelate textures over time, and create a touch‑driven donut wave that tints the underlying layer. Notes limits: works only on SwiftUI views, one texture parameter max, no Metal debugger for stitchable functions, and simple shaders run fast while complex ones degrade.
