Uploadcare iterate through array in PHP

I'm using the Uploadcare multi-upload widget and get a group ID back on post. When I call the API to list the files in the group, I want to extract certain pieces of information about each file (uuid, mime_type, original_filename, etc).

Here is my code:

$privateFiles = $_REQUEST['privateFiles'];    
$ucApi = new Uploadcare\Api(public_key_removed, private_key_removed);
$group = $ucApi->getGroup($privateFiles);
$files = $group->getFiles();        

foreach ($files as $ucFile)
    {   
        echo $ucFile['uuid'];
    }

When I try to do this, I receive this error: Fatal error: Cannot use object of type Uploadcare\File as array

I'm definitely getting the data back from the API but just having an issue trying to parse it. Here's a sample of what I'm getting back:

Uploadcare\File is an object, so you should treat it like one.

To get UUID, there's a method: $file->getUuid().

For other meta data you can use data array:

foreach ($files as $file)
{   
    echo $file->getUuid();
    echo $file->data['is_image'];
    echo $file->data['datetime_uploaded'];
    // etc
}
