How do I rasterize and cache layers for performance in Swift?

In Swift, rasterizing and caching layers can significantly enhance performance when rendering complex views. This approach can minimize CPU usage by converting vector graphics into a bitmap format that can be rendered quickly.

// Example of rasterizing a UIView in Swift let myView = UIView() myView.frame = CGRect(x: 0, y: 0, width: 200, height: 200) // Set up your view's layers properties if needed myView.backgroundColor = UIColor.red // Create a graphics context to rasterize the view UIGraphicsBeginImageContextWithOptions(myView.bounds.size, false, 0.0) myView.layer.render(in: UIGraphicsGetCurrentContext()!) let rasterizedImage = UIGraphicsGetImageFromCurrentImageContext() UIGraphicsEndImageContext() // Now you can cache this image for future use to improve performance let imageView = UIImageView(image: rasterizedImage) imageView.frame = myView.frame
