list all file URLs in xCode Group

Question

I have a yellow folder "Group" name "pdfs" in my Xcode directory. I need to list all file URLs PDFs in the folder to list it in my view.

   func listDir(dir: String) {
        // Create a FileManager instance
        
        let fileManager = FileManager.default
        let documentsURL = fileManager.urls(for: .documentDirectory,
                                            in:.userDomainMask)[0].appendingPathComponent(dir)
        do {
            let fileUrls = try fileManager.contentsOfDirectory(at:documentsURL, includingPropertiesForKeys: nil)
            // process files
            print(fileUrls)
        } catch {
            print("Error while enumerating files \(documentsURL.path): \(error.localizedDescription)")
        }

I had this error

Error while enumerating files /Users/user/Library/Developer/CoreSimulator/Devices/EF0F4EB3-CFB0-42F0-B7F5-B36034508BA2/data/Containers/Data/Application/08019A23-FDD9-4FF8-AC1F-2C13CE293BA5/Documents/pdfs: The file “pdfs” couldn’t be opened because there is no such file.

this the solution from Swift - How do I get the file path inside a folder

make sure to add the blue folder to your code project

and the code

    func listDir(dir: String) -> [URL]? {
    let fileManager = FileManager.default
    let documentsURL = Bundle.main.resourceURL!.appendingPathComponent(dir)
    var fileUrls:[URL]?

    do {
        fileUrls = try fileManager.contentsOfDirectory(at:documentsURL, includingPropertiesForKeys: nil)
        return  fileUrls
        
    } catch {
        print("Error while enumerating files \(documentsURL.path): \(error.localizedDescription)")
        return nil
    }
}
