Ruler

A simple AR ruler app can measure length & area, built with SwiftUI + ARKit

Requirements

• Swift 5.0+
• iOS 15.0+
• Xcode 26.0+
• An ARKit capable device (A9+) to run the AR measurement

Architecture

• SwiftUI app lifecycle (RulerApp) with the UI entirely in SwiftUI (ContentView, SettingView)
• ARSCNView is embedded via UIViewRepresentable (ARViewContainer) and the AR measurement logic lives in a single observable MeasurementModel
• SceneKit measuring nodes (LineNode, LineSetNode, FocusSquare, Plane) are shared model/view-logic
• The old OpenCV dependency was replaced by a pure Swift plane fitting implementation, and ARKit usage uses the modern ARRaycastQuery based API

Install

• AppStore (recommend)

  ARuler https://itunes.apple.com/us/app/id1287068680

• Manually compile

  1. git clone https://github.com/TBXark/Ruler
  2. Open Ruler.xcodeproj with Xcode and build

This project has no external dependencies — everything is managed natively by Xcode / Swift Package Manager. The old OpenCV (CocoaPods) dependency was replaced by a pure Swift plane fitting implementation, and deprecated ARKit APIs were migrated to the modern ARRaycastQuery based API.

To regenerate the Xcode project, install XcodeGen and run xcodegen generate.
