How to display folders in the file list Dropbox API (Swift 5)

[VyacheslavB]

I get a list of the user's files and then filter it to show only the music files. But I also want to see subfolders. How should I set up my filter for this? Could you help me.
My function where I get the list of files looks like this:

I also want to be able to enter a subfolder, as I understand it, for this I need to insert the path to the subfolder in path: "/ someFolder". But how can I get this path?

If you want to access subfolders as well when listing a folder, you can set recursive:true when calling listFolder. That will make the results include nested entries as well. 

Alternatively you can call separately to specifically list a particular subfolder, by passing in the path. To do so, get and pass in the relevant Metadata.pathLower.

Either way, make sure you also have listFolderContinue implemented (as documented under listFolder) to make sure you're getting all of the entries.

If I want to use the second option (using the folder path), then how do I display only music files and folders? I use .hasSuffix for sorting, but then I cannot see the folder in the list.
How can I separate folders from files in code. A file has its extension, but how to filter so that folders are visible in the list too?

As you understand, I want to have some attribute to know this is folder or file.

To check if a particular entry is a file or a folder, you can check the type of the entry, such as by switching on it as shown in this example.

When I try to use code from example, I get a warning: Cast from 'Files.ListFolderResult' to unrelated type 'Files.FileMetadata' always fails.
Maybe there is another option or a better example? Or am I doing something wrong?

[Greg-DB]

You're trying to cast the ListFolderResult itself, which isn't a type of Metadata. You should instead be casting each Metadata object in the ListFolderResult.entries array.

Hi Viyalexhab,

How do you declare the variable fileList? 

I'm trying t do the same thing, so I can append the files to it. But I can't figure out what type of variable you need to use to be able to append. 

Thanks!
