# iPadOS Split View App Template in SwiftUI (Free) > By Lawrence Arya, Founder & CEO of VP0.

Use SwiftUI's NavigationSplitView for the sidebar-list-detail structure and its automatic collapse behavior, design each column from a free VP0 screen, and wire selection state so choices flow column to column. Test full screen, in Split View, and in Slide Over. An iPad app that just stretches an iPhone layout to fill the screen feels wrong. iPadOS expects multi-column layouts, a sidebar, a list, and a detail view side by side, which SwiftUI provides directly. The short answer is, use SwiftUI's NavigationSplitView for the two or three-column structure, design each column from a free VP0 screen, and make sure the layout adapts when the app is in a narrow Split View or Slide Over. The goal is an app that uses the iPad's space well, not an enlarged phone screen. ## Why iPad needs a different layout The iPad's large screen and multitasking change the rules: users expect to see a sidebar and content together, and they may run your app in a narrow split alongside another. Apple's [iPad layout guidance](https://developer.apple.com/design/human-interface-guidelines/layout) and SwiftUI's column navigation are built for this. Ignoring it (a single stretched column) wastes the screen and feels unfinished, which undercuts the polish that supports retention, around [25%](https://getstream.io/blog/app-retention-guide/) on day one. The right model is adaptive: show multiple columns when there is room, collapse gracefully to a stack when there is not. ## How to build a split-view layout in SwiftUI VP0 is a free iOS design library for AI builders. Design each column as its own screen from VP0 (a sidebar list, a content list, a detail view), then assemble them with [SwiftUI's NavigationSplitView](https://developer.apple.com/documentation/swiftui/navigationsplitview), which handles the two or three-column structure and the collapse behavior automatically. Have Cursor or Claude Code wire the selection state so picking an item in one column updates the next. Test in full screen, in a 50/50 Split View, and in Slide Over to confirm it adapts. Keep the same design language across columns so it reads as one app. For the data behind the columns, see [SwiftData UI template](/blogs/swift-data-ui-template/). ## Split-view building blocks Here is what each part should do. | Part | What to get right | |---|---| | Sidebar | Top-level sections, persistent | | Content list | Items for the chosen section | | Detail view | The selected item, full width | | Selection state | Picking flows column to column | | Adaptation | Collapses cleanly when narrow | ## A worked example Say you have a notes app. On iPad, a NavigationSplitView shows folders in the sidebar, notes in the middle, and the selected note's content on the right, each column built from a VP0 design. Selecting a folder filters the note list; selecting a note shows it in detail. In a narrow Split View or on iPhone, the same code collapses to a normal push navigation. Build each column once and let NavigationSplitView handle the adaptation. Mind the empty detail state too: when nothing is selected yet, the detail column should show a helpful placeholder, not a blank void, so the layout never looks broken on first launch. For the overall app build, see [how to build an iOS app with AI](/blogs/how-to-build-an-ios-app-with-ai/); for a starter that includes structure like this, [React Native boilerplate with auth and payments UI](/blogs/react-native-boilerplate-with-auth-and-payments-ui/). ## Common mistakes The most common mistake is shipping a stretched single-column iPhone layout on iPad, which wastes the screen. The second is not testing in Split View and Slide Over, where a fixed layout breaks. The third is hardcoding widths instead of letting the split view adapt. The fourth is losing selection state between columns, so the detail view does not follow the list. The fifth is a different visual style per column, making it feel like separate apps stitched together. ## Key takeaways - iPad expects multi-column layouts; a stretched phone layout feels unfinished. - Use SwiftUI's NavigationSplitView for the columns and its automatic collapse behavior. - Design each column from a free VP0 screen and keep one design language across them. - Test full screen, in Split View, and in Slide Over so the layout adapts everywhere. ## Frequently asked questions How do I build an iPadOS split-view layout in SwiftUI? Use NavigationSplitView for the two or three-column structure (sidebar, content list, detail), design each column from a free VP0 screen, and wire the selection state so choices flow column to column. It collapses to a stack automatically when narrow. Why does my iPad app look like a big iPhone app? Because it uses a single stretched column. iPad expects multiple columns; adopt NavigationSplitView so you show a sidebar and content together and use the larger screen properly. Do I need separate code for iPhone and iPad? Often not. NavigationSplitView adapts: it shows columns on iPad and a normal stack on iPhone or in narrow Split View, so one layout serves both with the right behavior. What should I test for iPad layouts? Full screen, a 50/50 Split View, and Slide Over. A layout that only works full screen will break in multitasking, which iPad users rely on. ## Frequently asked questions ### How do I build an iPadOS split-view layout in SwiftUI?
