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

Thanks, that worked perfectly! My app is showing the folders now.
You’re right, to open subfolders you just need to use the folder path that comes in the API response, look for pathLower or pathDisplay in the file list and pass that into your next request. By the way, if your app screen goes blank or doesn’t show folders correctly, you can check your screen to see if it’s a display problem.
Hi Greg, thank you so much. I'm new to Swift and still figuring out many things.
This was of great help!

roggerCorrea It looks like fileList would be an array, perhaps initialized like 'var fileList = [Any]()', or maybe more ideally 'var fileList = [Files.Metadata]()'.
Your cast is failing because you're attempting to cast the entire array of Metadata, that is, your 'response', which is the listFolderResult?.entries, instead of individual Metadata entries.
You should instead first iterate over the entries to get each entry, like the 'for entry in result.entries {' line in the original post shows.
I get this error, does anybody knows what to do?
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!

Thanks, it really helped me!

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.
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?
