macos swift nsimage

I'm converting an old project and I need help solving I'm writing unit tests and I'm not sure how to approach I'm working with an scenario while trying to load images from a remote URL in my macOS app that has App Sandbox enabled. When I attempt to initialize an `NSImage` with a URL, I receive an `NSImageRenderingError` that states, "The image could not be loaded because the image data is not valid". Here's the relevant code snippet I'm using to fetch and display the image: ```swift import Cocoa func loadImage(from url: URL) { DispatchQueue.global().async { if let imageData = try? Data(contentsOf: url) { DispatchQueue.main.async { let image = NSImage(data: imageData) if image == nil { print("Failed to create NSImage from data") } else { self.imageView.image = image } } } else { print("Failed to fetch data from URL: \(url)") } } } ``` I've made sure that the URL is valid and accessible. I also confirmed that the App Sandbox is configured to allow network access. I tried using `NSURLSession` for better behavior handling and async loading, but I still ended up with the same behavior. Here’s a simple version of the URL I’m trying to use: ```plaintext https://example.com/image.png ``` Now, I’m wondering if there are any specific sandbox permissions or configurations I might be missing that prevent remote images from loading correctly. Is there a recommended approach to loading images in a sandboxed environment, or any additional behavior handling I should implement to troubleshoot this further? Any insights would be greatly appreciated. Am I missing something obvious? I've been using Swift for about a year now. Has anyone dealt with something similar? Is there a simpler solution I'm overlooking?
