Get all files form a group folder?

问题

After long struggling, I just can't do the most simple and obvious thing, to read all files/photos from a specific folder(group) that I create in my app by "Add new group" menu on the left side of Xcode.

I have tried so many pieces of code, all tells me there is no such folder, but the folder is there in front of me.

     if let path = Bundle.main.resourcePath {

        let imagePath = path + "/Artworks"
        let url = NSURL(fileURLWithPath: imagePath)
        let fileManager = FileManager.default

        let properties = [URLResourceKey.localizedNameKey,
                          URLResourceKey.creationDateKey, URLResourceKey.localizedTypeDescriptionKey]

        do {
            let imageURLs = try fileManager.contentsOfDirectory(at: url as URL, includingPropertiesForKeys: properties, options:FileManager.DirectoryEnumerationOptions.skipsHiddenFiles)

            print("image URLs: \(imageURLs)")
            // Create image from URL
            //var myImage =  UIImage(data: NSData(contentsOfURL: imageURLs[0])!)

        } catch let error1 as NSError {
            print(error1.description)
        }
    }

 The file “Artworks” couldn’t be opened because there is no such file."

What else should I do to simply be able to arrange lots of photos inside a group folder and read only from that folder all the photos names/urls ?

EDIT : Printing the path gives me :

/Users/me/Library/Developer/CoreSimulator/Devices/673ED39D-61D6-4F2D-BAC9-3EC7C4AC2089/data/Containers/Bundle/Application/7CDD3B62-B04O-4A48-8716-D83F6EDA5689/appName.app/Artworks

You have to create folder reference while adding the images in Xcode project.

Once folder reference is created, it will look like below.

The files can be read using the below code.

let directory = Bundle.main.path(forResource: "iPad", ofType: nil, inDirectory: "1")
        let contentsArray = try? FileManager.default.contentsOfDirectory(atPath: directory!)

The contentsArray will have a count of 7 in this case.

Actually, amazingly, for 2 days no one could tell me the real issue here. Creating a group, is completely different from dragging a folder into the project.

For some reason, with Apple, its always complicated with files. I have to figure out the NOT so intuitive approach that a group that looks like a folder, is nothing but a nice way to look at something, and will not create a real folder accessible by the file manager.

Simply put, create a blue folder outside Xcode and drag it in.
