A guide on how to use Swift and Core Image for processing images with filters, providing practical examples.

import UIKit import CoreImage class ImageProcessor { func applyFilter(to image: UIImage) -> UIImage? { guard let ciImage = CIImage(image: image) else { return nil } let filter = CIFilter(name: "CISepiaTone") // Example filter filter?.setValue(ciImage, forKey: kCIInputImageKey) filter?.setValue(0.8, forKey: kCIInputIntensityKey) guard let outputImage = filter?.outputImage else { return nil } let context = CIContext() if let cgImage = context.createCGImage(outputImage, from: outputImage.extent) { return UIImage(cgImage: cgImage) } return nil } } // Usage let originalImage = UIImage(named: "example.jpg") // Load your image let processor = ImageProcessor() let filteredImage = processor.applyFilter(to: originalImage)
