SwiftUI: Build a Before & After Slider with GeometryReader | No Commentary

Build a reusable Before & After image comparison slider in SwiftUI using GeometryReader. In this video, we use GeometryReader to measure the available space, calculate the comparison position, and dynamically reveal each side of the image as the user drags the handle. What you’ll build: • A reusable image comparison component • Dynamic layouts with GeometryReader • An interactive slider using DragGesture • Before and After image overlays • Position calculations based on the container size • A draggable comparison handle • A clean component ready for any SwiftUI project Perfect for photo editors, filters, design previews, transformations, and any interface that compares two visual states. No commentary — just SwiftUI code and background music. #SwiftUI #GeometryReader #DragGesture #ImageComparison #BeforeAndAfter #ReusableComponents #SwiftProgramming #iOSDevelopment #Xcode #CodeAndCraft
