  • Easy integration: GPUImage is designed to be easy to integrate into your iOS projects. It provides a simple API for capturing video from the camera, applying filters, and displaying the results.

  • GPU acceleration: By leveraging the GPU, GPUImage can perform complex image and video processing tasks much faster than if it were running on the CPU. This is particularly important for real-time applications where performance is critical.

How to Use:

To use GPUImage, you'll first need to install it in your project. You can do this using CocoaPods or by manually adding the source files to your project. Once you've installed GPUImage, you can start using it to capture video from the camera and apply filters. Here's a basic example:

import GPUImage

class ViewController: UIViewController {

    let camera = GPUImageVideoCamera(sessionPreset: AVCaptureSession.Preset.high, cameraPosition: .back)
    let filter = GPUImageSepiaFilter()
    let displayView = GPUImageView()

    override func viewDidLoad() {
        super.viewDidLoad()

        camera?.addTarget(filter)
        filter?.addTarget(displayView)

        view.addSubview(displayView)
        displayView.frame = view.frame

        camera?.startCapture()
    }
}

This code captures video from the camera, applies a sepia filter, and displays the result in a GPUImageView. You can easily replace the GPUImageSepiaFilter with any other filter from the GPUImage library or create your own custom filter.

2. SwiftQRScanner

If you're looking to add QR code scanning functionality to your iOS app, SwiftQRScanner is a great option. This library provides a simple and easy-to-use API for scanning QR codes and barcodes. It supports a wide range of code types and can be customized to fit your specific needs.

How to Use:

To use SwiftQRScanner, you'll first need to install it in your project. You can do this using CocoaPods or by manually adding the source files to your project. Once you've installed SwiftQRScanner, you can start using it to scan codes. Here's a basic example:

import SwiftQRScanner

class ViewController: UIViewController {

    let scanner = SwiftQRScanner()

    override func viewDidLoad() {
        super.viewDidLoad()

        scanner.delegate = self
        scanner.startScanning()

        view.addSubview(scanner.view)
        scanner.view.frame = view.frame
    }
}

extension ViewController: SwiftQRScannerDelegate {
    func qrScanner(_ controller: SwiftQRScanner, didFindCode code: String) {
        print("Found code: \(code)")
        controller.stopScanning()
    }
}

This code creates a SwiftQRScanner object, sets the delegate, and starts scanning for codes. When a code is found, the qrScanner(_:didFindCode:) method is called, which prints the code to the console and stops scanning.
