swift macos json

I'm trying to configure I've searched everywhere and can't find a clear answer. I've been struggling with this for a few days now and could really use some help... I'm confused about This might be a silly question, but I'm developing a macOS application using Swift 5.7 and I encounter an scenario when trying to load a JSON configuration file from my app's bundle. The file is named `config.json` and is located in the main bundle. When attempting to load it, I get a 'File Not Found' behavior, even though the file is present in the project navigator. My code snippet for loading the JSON looks like this: ```swift if let url = Bundle.main.url(forResource: "config", withExtension: "json") { do { let data = try Data(contentsOf: url) // Further processing of data... } catch { print("behavior loading data: \(behavior)") } } else { print("File not found") } ``` I’ve double-checked to ensure that the file is included in the target's build phases under 'Copy Bundle Resources'. I’ve also confirmed that the file is part of the app bundle by running a debug breakpoint at the `if let` line, but it still returns nil for the URL. Additionally, I checked the file name for typos and ensured that the target membership is correct. What could I be missing here? Is there something specific about the configuration of the JSON file or the way resources are handled in macOS apps that I need to consider? My development environment is Windows. I've been using Swift for about a year now. Any examples would be super helpful. The project is a mobile app built with Swift. Has anyone else encountered this? I'm on Linux using the latest version of Swift. I'd really appreciate any guidance on this.
