MetadataScanner

MetadataScanner is a metadata scanning library built for SwiftUI apps. It provides a Button-like view component to make scanning view easy to implement.

Requirements

• iOS 14.0+
• Xcode 12.4+
• Swift 5.3+

Usage

You can use MetadataScanner just like any other View component inside a body: some View property in your projects.

One thing you need to notice is that the initializer may return nil if no available camera found. You can replace it with any placeholder view using if let else statement (check the example), or if you don't need a placeholder you can also just ignore it, and SwiftUI will handle it as there is no view at all.

Example

MetadataScanner(videoGravity: .resizeAspectFill,
                objectTypes: [.qr],
                scans: true,
                onScannedObjectUpdate: { print($0) })

Installation

Use SwiftPM (in Xcode)

1. Xcode > File > Swift Packages > Add Package Dependency
2. Add https://github.com/el-hoshino/MetadataScanner.git
3. Select "Up to Next Major" with "0.1.0"

Use SwiftPM (using Package.swift)

1. Create a Package.swift file.
2. Add dependencies like below:

   // swift-tools-version:5.3
   // The swift-tools-version declares the minimum version of Swift required to build this package.
   
   import PackageDescription
   
   let package = Package(
       name: "MyAwsomeProject",
       dependencies: [
           .package(url: "https://github.com/el-hoshino/MetadataScanner.git", from: "0.1.0")
       ],
       targets: [
           .target(name: "MyAwsomeProject", dependencies: ["MetadataScanner"])
       ]
   )
