The most effective iOS prototyping tools in 2026 include Figma (the best tool for collaborative and high-fidelity design), ProtoPie (the best prototyping tool for advanced interactions) and Xcode/SwiftUI (the best tool for capturing native functionality). These tools enable designers to create interactive, high-fidelity prototypes that replicate real iOS app behaviour for testing and development.
Which is the best prototyping tool for iOS varies depending on your needs and skill. If you’re simply testing out your Figma designs on an iPhone to get the feel for the sizing and spacing, use the prototyping tool within Figma. ProtoPie remains one of the best all-around prototyping tool should you be designing for multiple devices, though it comes with a learning-curve. But for anything more complicated, and if you’re willing to learn a bit of SwiftUI, use Xcode.
Figma
As the leading design tool for creating, testing, and sharing interactive, high-fidelity iOS prototypes with robust community UI kits (including some from Apple), Figma provides a seamless prototyping tool inside the design app you’re already using. However Figma does have some limitations when it comes to prototyping—memory and performance issues, conflicts with native interactions, no real keyboard and most importantly with fixed screen-sizes you’ll need to design your frames with the exact iPhone model in mind for testing. Of course if you’re already designing your app in Figma, you’re already in the file and you won’t need to export any assets.
I good feature in Figma that will greatly help you build your prototypes, especially using Xcode, is Dev Mode. Of course this is a paid feature requiring at a minimum, a full-seat Professional tier account. (Unfortunately the lower-priced standalone Dev seat doesn’t include the Design tools).
Figma Make
While the Make feature only just arrived in 2025, the AI powered tool will follow your design and design system components as you prompt your way to a real-code responsive website. If you’re already familiar with Figma and prompting an LLM chatbot, Figma Make’s interface will be easy to pickup but you will also learn the Make allows you to adjust some of the type sizes and attributes without having to write out a full prompt. However this feature doesn’t always stick. In building one mobile web prototype, I followed the tips from Figma including starting desktop first but this failed. I also found the app refused to follow the design library I had attached, so despite the design that I pasted in having the correct type styles referenced in the library, some type wouldn’t appear bold or the correct size, and attempts to manual adjust the text, even page headings, wouldn’t stick. Of course Figma Make will only produce a website which you’d need to load in Safari, so you won’t get the full app experience that you would expect with an iOS app.

ProtoPie
Ideal for your more advanced, high-fidelity prototypes that involve more complex interactions, sensor usage (gyroscope, camera) and smart device logic, ProtoPie won’t give you the level of control that you get with SwiftUI, however the learning curve is easier to adapt to though it still requires learning a new tool. You will of course need the ProtoPie Player iOS app on your iPhone in order to run your prototypes. ProtoPie lets you import your designs from Figma (or Sketch and XD if you’re using those apps). And you are now constrained to just prototyping for iOS with ProtoPie—the app is capable of prototyping multiple platforms. There is a free tier but you are limited, and the Basic tier starts at $25 a month (on the annual plan—otherwise it’s $29 month to month).

Xcode & SwiftUI:
My personal bias here is obviously with using Xcode since it enables us to build functional, high-fidelity prototypes that can be installed on any iPhone model, providing the most realistic testing experience. SwiftUI allows you to not only use native iOS hardware features, the is not “player” app required to enable your prototypes to run on the phone, and not just the phone size you designed for but any iPhone size. Getting your prototype app on your iPhone is relatively simple, and this works great when you can hand the test phone to the person testing your app, however you’ll need to use an app such as TestFlight if you need to get the prototype onto a user’s phone if you’re doing remote testing.

Adobe XD:
Adobe’s free answer to Sketch is effectively discontinued as it has been placed into “maintenance mode” with no new feature development or active interest from Adobe. While existing Creative Cloud subscribers can access and continue to use XD, it is no longer sold as a standalone product, leading many designers to transition to tools like Figma, which we know Adobe tried to buy.
iOS prototyping tips
Look & Feel: utilizing resources such as the SF Pro font and iOS UI Kits ensures that prototypes visually and functionally resemble real applications.
Fidelity: you may find you just need to see your designs on a phone without getting to the user testing phase. While there are several low-fidelity prototyping apps, you can easily stick with your current design tool such as Figma.
Handoff: Figma, for example, has the ‘Dev Mode’ feature that lets you turn your designs into code right away, which makes it easier for developers to get on board but also for you to access the code for your design.
