How Apple Asset Catalogs Work
Points vs Pixels
iOS layout logic uses points. A 44×44 pt icon renders at 44px on standard displays (@1x), 88px on Retina (@2x), and 132px on OLED Super Retina (@3x).
Template Rendering
Setting the render intent to template in Contents.json strips original colors, allowing SwiftUI to tint the image dynamically using .foregroundStyle().
Drag-and-Drop to Xcode
Drag the downloaded .imageset folder directly into Assets.xcassets. Xcode will catalog the scale variants automatically without manual linking.
