swift - SwiftyDropbox list folders only -

im using swiftydropbox sdk in ios application, im trying list folders in app user can choose folder (not file).

in viewcontroller => viewdidload

override func viewdidload() {     super.viewdidload()      guard let dropboxclient = dropboxclientsmanager.authorizedclient else{         return     }      let listfolders = dropboxclient.files.listfolder(path: "")     listfolders.response{ response, error in         guard let result = response else{             return         }          entry in result.entries{             print(entry)         }     }     // additional setup after loading view, typically nib. } 

entry >

  {        id = "id:0gmpvywuveaaaaaaaaaabw";       name = "folder a";       "path_display" = "/folder a";       "path_lower" = "/folder a";   } 

how can find entry folder , contains sub folder or not?

you can cast each entry inside of result.entries for loop this

override func viewdidload() {     super.viewdidload()      guard let dropboxclient = dropboxclientsmanager.authorizedclient else{         return     }      entry in result.entries{        guard let file = entry as? files.foldermetadata else{          return        }         // folders        print(entry)         // *********  or         gurad let entry files.foldermetadata else{          return        }         // folders        print(entry)     } }
