Swift Package Manager

The Swift Package Manager is a tool for automating the distribution of Swift code and is integrated into the swift compiler. It’s integrated with the Swift build system to automate the process of downloading, compiling, and linking dependencies.

Once you have your Swift package set up, adding as a dependency is as easy as adding it to the dependencies value of your Package.swift.

dependencies: [
    .package(url: "https://github.com/sparrowcode/SPQRCode", .upToNextMajor(from: "1.0.0"))
]

CocoaPods:

CocoaPods is a dependency manager. For usage and installation instructions, visit their website. To integrate using CocoaPods, specify it in your Podfile:

pod 'SPQRCode'

Manually

If you prefer not to use any of dependency managers, you can integrate manually. Put Sources/SPQRCode folder in your Xcode project. Make sure to enable Copy items if needed and Create groups.

Usage

To show QRCode scanner:

let qrCodeController = SPQRCodeViewController()

qrCodeController.cameraFoundHandler = { value in
    print(value)
}

viewController.present(qrCodeController, animated: true, completion: nil)

If need with specific view for frame and preview, use this:

let frameView = UIView()
frameView.layer.borderWidth = 3.0

let previewLabel = UILabel()

let qrCodeController = SPQRCodeViewController()
qrCodeController.customFrameView = frameView
qrCodeController.customPreviewView = previewLabel

qrCodeController.cameraFoundHandler = { [weak previewLabel] value in
    previewLabel?.text = value
}

viewController.present(qrCodeController, animated: true, completion: nil)

Optionaly you can create subclass of SPQRCodeViewController for more control
