This guide walks you through everything from downloading 10x to watching your first iOS app run on the Simulator. The whole process takes just a few minutes.
1

Download and install 10x

Download the latest 10x .dmg from the 10x website. Open the DMG, then drag 10x.app into your Applications folder.10x is available on two release channels — stable and beta — and uses Sparkle to deliver automatic updates after you install.
2

Pass the system check

When you launch 10x for the first time, a System Check screen verifies that your Mac is ready to build and preview iOS apps. It checks for two things:
  • Xcode installed — Xcode 16 or later, opened at least once to complete first-launch setup
  • iOS 26+ simulator available — at least one iPhone Simulator runtime installed via Xcode > Settings > Platforms
If anything is missing, 10x shows a setup button next to the failing requirement. Click it to install or configure what is needed. The screen rechecks automatically every few seconds, so once setup completes you can continue immediately.
If Xcode is not installed, click Get Xcode to open the App Store page. After installing, open Xcode once so it can finish its own first-launch setup, then return to 10x.
When both requirements show a green checkmark, click Continue.

Sign in

After the system check passes, 10x shows the sign-in screen. Click Sign in with Google to authenticate. Your browser opens briefly to complete the OAuth flow, then returns you to the app.

Describe your first app

You land on the home screen with a text field and a row of suggestion chips — quick prompts like “habit tracker”, “recipe app”, or “workout log” to help you get started if you do not have a specific idea yet.Type a description of the app you want to build, or tap one of the suggestion chips to use it as your starting point. Be as specific or as broad as you like — the AI asks clarifying questions during the planning phase if it needs more detail.Press Return or click the send button to continue.

Go through the onboarding wizard

A three-step onboarding wizard opens before the AI starts building. You can work through each step or click Skip to begin immediately.
  • Design Direction — choose a visual style for your app. Options include Clean & Minimal, Sharp & Focused, Bold & Expressive, Warm & Inviting, and more. A live mini-preview shows what your chosen palette and typography look like before you commit.
  • Target Audience — select who the app is for. You can pick multiple audiences.
  • Additional Details — add any extra context: specific features, inspirations, or reference images you want the AI to incorporate.
When you are done, click Start Building. If you prefer to jump straight into the AI conversation, click Skip in the top-right corner of the wizard.
You can also click Begin Immediately or Select Your Style when creating a new project from the home screen, depending on how much setup guidance you want before the AI starts.

Watch it build

10x opens the builder workspace, a three-pane layout:
  • Left sidebar — a VS Code-style file explorer showing every Swift file the AI generates
  • Center panel — the chat view with the AI’s messages, inline questions, and tool steps
  • Right panel — the Simulator preview and project plan
The AI first enters Plan mode: it researches your concept, may ask a clarifying question or two in the chat, and creates a project plan. Once planning is complete, it switches to Build mode and starts writing SwiftUI code. You can follow along in the file explorer as files are created and edited in real time.
7

Preview your app on the Simulator

When the AI finishes building, 10x automatically boots an iPhone Simulator, compiles your app, installs it, and captures a screenshot. The screenshot appears in the right panel so you can see your running app without switching to the Simulator window.From here you can continue the conversation: ask the AI to add a new screen, change the color scheme, fix a bug, or anything else. Each change triggers a new build and preview cycle.
