ScrollCraft vs Swoop

ScrollCraft is a native iPhone, iPad, and Mac app for SwiftUI developers who want to design scrollTransition() effects visually, then copy or export the generated SwiftUI code. Use live sliders to tune opacity, scale, offset, blur, saturation, colors, and corner radius while the preview updates immediately. When the transition feels right, open the code view and take the generated SwiftUI into your own project. Highlights: Live preview for scrollTransition() experiments A focused Apple-platform workflow for exploring SwiftUI scroll effects Phase-specific controls for topLeading, identity, and bottomTrailing Readable SwiftUI code generated from your exact settings One free code copy, with a one-time Pro unlock for unlimited copying Pro export to .swift files and saved local presets No account, no tracking, no ads, and no subscription ScrollCraft is intentionally focused: it is not a code editor, compiler, or general animation suite. It is a small, native tool for learning, tuning, and reusing SwiftUI scroll transitions on iPhone, iPad, and Mac.

Write SwiftUI on your phone, watch it run, and paste it into Xcode. Swoop is a canvas for postcard-sized components. Type one, press play, and it runs for real — springs, timing and trigonometry computed on the device at the frame rate you feel. Copy hands back plain SwiftUI that compiles. Most SwiftUI apps are catalogues you browse. This is the one where you write it. WHAT IT PLAYS Swoop runs a documented subset of SwiftUI, on device. • Text, Image, Button, Toggle, Spacer, Divider • VStack, HStack, ZStack, ForEach, TimelineView • Circle, Capsule, Rectangle, RoundedRectangle • frame, padding, offset, opacity, scaleEffect, rotationEffect, zIndex • fill, stroke, trim, background, overlay, clipShape, shadow • animation, onAppear, symbolEffect, sensoryFeedback • @State, helper funcs, computed views, if/else, ranges • sin, cos, tan, sqrt, pow, min, max, .pi If Swoop cannot play something exactly the way Xcode would, it refuses and points at the line rather than guessing. What you copy always compiles. Swoop is for one component at postcard size — not for building whole screens on a phone. ScrollView, List, NavigationStack, GeometryReader and TextField are deliberately not included. A REAL EDITOR • Line numbers and syntax colour • Autocorrect, smart quotes and autocapitalisation switched off • Every file in your library previews itself, running, in the list POST IT AND RECORD IT • Publish a component to the community, free, under your username • Anyone can play it and take the source • Record three seconds of it running and share the video • Like and view counts on everything published PRIVACY • Your files are saved on your phone • Nothing is uploaded, read by us, or used to train anything • A file leaves the device only when you publish or share it • Writing, playing and copying never need an account • Sign in with Apple or Google only to publish or like • Delete your account from inside the app, any time SWOOP PRO • A profile page — your picture and a grid of your work • Clean recordings, without the Swoop mark • Sign a recording with your avatar and username • Backdrops for recordings • Post a component without handing over the source Writing, playing, copying and publishing stay free.
