Use open-source components for the plumbing, vet the license and security, and own your screens from a free VP0 design.

**TL;DR.** Open source UI elements come as copy-own components or installable libraries; copy-own keeps control. Vet everything (license, maintenance, security) because roughly 71% of apps leak data, and start your screens from a free VP0 design that your AI tool turns into components you own.

When you need buttons, cards, inputs, sheets, and other building blocks for an iOS app, "open source UI elements" sound like the fast path. They can be, but only if you vet them. The short answer is, use reputable open-source component libraries for the plumbing, check the license and security of anything you pull in, and start your actual screens from a free VP0 design so the look is yours rather than a default theme. That combination is free and keeps you in control.

## What "open source UI elements" really means for iOS

There are two layers. One is reusable components (a button, a list row, a modal) that you can copy into your own code and restyle. The other is full UI libraries you install as a dependency. Copying components into your project (the shadcn approach) keeps control in your hands; installing a heavy library trades control for speed. Either way, vetting matters: roughly [71%](https://cybernews.com/security/) of mobile apps were found to leak sensitive data in one analysis, and unvetted dependencies are a common path in. So read the license, check that the project is maintained, and scan for anything that phones home.

## How to get free UI elements you can trust

VP0 is a free iOS design library for AI builders. Rather than hunting for a kit, pick a design, copy its link, and have Cursor or Claude Code turn it into clean [React Native](https://reactnative.dev/) or SwiftUI components you own. For genuinely reusable cross-app pieces, pair that with a maintained open-source approach and respect each license; an [MIT license](https://opensource.org/license/mit), for example, allows free use but comes with no warranty, so the responsibility to read the code is yours. To set up a small, consistent set, build base components once (Button, Card, Input) and reuse them, as covered in [iOS app design principles for builders](/blogs/ios-app-design-principles-for-builders/).

## Where to get UI elements, compared

Here is how the options compare for an indie builder.

| Source | Control | License risk | Best for |
|---|---|---|---|
| Copy-own components | Full | Low (you wrote it) | Custom look, long term |
| Open-source library | Medium | Read the license | Speed, common widgets |
| Random ZIP / dump | Low | High (unknown) | Avoid |
| VP0 design + AI | Full | Low (your code) | Screens that look intentional |

## A worked example

Say you need a settings screen with toggles and a profile card. Pull a VP0 settings design, copy the link, and ask your AI tool to build it as reusable components. If you also want a well-tested date picker, add a maintained open-source one as a dependency, after checking its license and last commit. Now your screen uses your own components for the custom parts and a vetted library only where it earns its place. For making the whole thing feel more polished, see [how to make my app look better](/blogs/how-to-make-my-app-look-better/), and for sourcing screens, [where to find iOS app design inspiration](/blogs/where-to-find-ios-app-design-inspiration/).

## Common mistakes

The most common mistake is installing a heavy UI library for one component you could have written in twenty lines. The second is ignoring the license and assuming "open source" means "do anything"; it does not, and brand assets are never covered. The third is pulling a component from a random dump without reading it, inviting the kind of leak the 71% figure describes. The fourth is letting every element come from a different source, so the app loses a consistent look. The fifth is never abstracting repeated UI into shared components.

## Key takeaways

- "Open source UI elements" means either copy-own components or installable libraries; copy-own keeps control.
- Vet everything: read the license, check maintenance, and scan for risk, because roughly 71% of apps leak data.
- An MIT license allows free use but with no warranty, so reading the code is on you.
- Start screens from a free VP0 design so the look is intentional, and reuse base components for consistency.

## Frequently asked questions

Where can I find open source UI elements for iOS for free? Use reputable open-source component libraries for common widgets after checking their license and maintenance, and start your screens from a free VP0 design that your AI tool turns into components you own.

Is it safe to use open-source UI components? It can be, if you vet them: read the license, confirm the project is maintained, and scan for anything suspicious. Unvetted dependencies are a common source of leaks.

What does the MIT license let me do? MIT allows free use, modification, and distribution, but with no warranty, so you are responsible for reading the code. It does not let you copy another brand's assets or identity.

Should I copy components or install a library? Copy small or custom components so you keep full control, and install a maintained library only for complex, well-tested widgets where it clearly saves time.
