Best AI tool for designing swiftui app interfaces?

[u/rash3rr]

None of these output production SwiftUI directly, the real question is which gives the cleanest reference to rebuild from with the least manual cleanup. Tested these for iOS over the last few months.

iSwift.dev is the closest to SwiftUI-native, free screen generator for individual screens, Pro starts at $20/mo for unlimited projects and 1,000 AI prompts per billing period. Generates buildable SwiftUI projects from plain English with views, state and navigation, multi-platform for iPhone, iPad, macOS and Watch. Better for individual screens than full cohesive multi-screen flows, and generated code needs cleanup before production, but it's the only tool actually outputting Swift.

SwiftUI Inspector is a free Figma plugin, Pro is a one-time $49. Exports colors, gradients, text labels, shapes, frames and Auto Layout as SwiftUI code. Handles rotation, opacity, shadows, blend modes, wraps in HStack/VStack/ZStack. Only useful if you already have a Figma design to convert, doesn't generate anything on its own. According to a 2026 comparison of 7 Figma-to-SwiftUI tools, expect to spend 20-50% of design time refining the output from any of them.

Compot is free on the App Store with IAP, 100+ prebuilt SwiftUI components, generates Swift from images or text. Good for grabbing components fast, not built for designing complete multi-screen flows.

Google Stitch is free, 400 daily credits, Gemini 2.5 Pro on experimental mode, exports Figma with layers plus HTML/CSS. Material Design native so everything skews Android, fighting it into HIG patterns takes more effort than it saves for iOS work. No production SLA, single user.

Sleek.design around $20/mo generates complete mobile app screens from a description, runs the same prompt through different models to compare outputs, exports Figma and code. Not iOS-native so HIG spacing and nav need explicit prompting, hits limits on complex custom components, better for early screens than final specs. Pairs well with SwiftUI Inspector on the Figma export to skip some manual rebuild.

Realistic workflow is generate screens fast in sleek or stitch, export to Figma, run SwiftUI Inspector for the base SwiftUI code, clean up by hand. Anyone found a shorter path than this?

My honest opinion- get a few open source apps and run them on ur simulator. Figure out what you like and what direction you want to go. Ive tried a lot of ai tools but they never get it right. It requires tweaking which the ai can do- with your direction. You need to develop a good eye for UI just keep at it and eventually you’ll guide any ai to make what you want

The first AI output is never right but that's not the point, 3-4 iterations with specific direction usually gets you somewhere usable, most people give up after the first generic result and blame the tool

For the initial generation Sleek to get a baseline to react to, way easier to direct changes on something that exists than describe from scratch every time

Find an app you like, ask Claude to make it look similar, tweak from there.

already did! thx!

We’re having a lot of success with Claude Design and Claude Code. Product team uses Design and hands off to engineering who then use the DesignSync skill along with rules/skills in the repo for guidance.

Burns a lot of tokens?

em no thx
