Scan Barcodes with a Single Tap
A complete barcode scanning solution for iOS. Every code, every format, instantly recognized.
The Problem
Building a barcode scanner requires wiring together multiple Apple frameworks: AVFoundation for camera access, Vision for barcode detection, and proper SwiftUI integration. The camera feed must be captured, processed frame by frame, and results must flow back to the UI, all while handling permissions and device compatibility.
The Solution
This complete iOS application provides a production ready barcode scanner:
- Camera Pipeline Setup - Properly configured AVCaptureSession with video output
- Vision Framework Integration - VNDetectBarcodesRequest for reliable detection
- SwiftUI Wrapper - UIViewRepresentable implementation for camera preview
- Real Time Results - Scanned codes displayed instantly using @Binding
The Benefits
- Save 12 to 20 hours of framework integration work
- Works immediately - build and scan in minutes
- Clean architecture with separate concerns for capture, detection, and display
- Permission handling included with Info.plist configuration
- Easy to customize for your specific barcode types
