How do I store private app data on Google Drive with my iOS app?

I have an iOS app that has a local database. I'd like to back that up for users who choose to sign in with Google. The web (https://developers.google.com/drive/web/appdata) and android (https://developers.google.com/drive/android/appfolder) have guides on how to do this, but I can't find a similar one for iOS. Does it exist?

Check this how this is working for me in swift 4.2 and above:

let googleDrive: GTLRDrive_File = GTLRDrive_File()
    googleDrive.name = "name.json"
    googleDrive.parents = ["appDataFolder"]
    let uploadParam: GTLRUploadParameters = GTLRUploadParameters(data: data, mimeType: "application/json")
    uploadParameters.shouldUploadWithSingleRequest = true;
    let queryDrive: GTLRDriveQuery_FilesCreate = GTLRDriveQuery_FilesCreate.query(withObject: metadata, uploadParameters: uploadParam)
    queryDrive.fields = "id"
    self.service.executeQuery(queryDrive) { (result, response, error) in
        if let file = response as? GTLRDrive_File {
            if (error == nil) {
                print(file.identifier)
               /// your code here
            } else {
                // handle error part
            }
        }
        else {
           //handle exception part 
        }
    }

"data" the json data you get this like below

let param = [["key": "value"], ["key": "value"], ["key": "value"]]
let data = try JSONSerialization.data(withJSONObject: param, options: .prettyPrinted)

If you already have code to upload a file to the user's Drive account, it is very easy to switch to uploading into the private app folder instead. When making the Files.insert call, the file will be added to all of the folders listed in the parents[] array. (If this array is empty, by default the file is added to the root folder.) To upload the file into the private app data folder, simply set the parents[] array to appfolder. You have to do this at the same time as uploading the file, because once it has been uploaded the file can't be moved between the user's drive and your app's private data folder.

(Note: you may need to use the regular REST API to do this, because Google's Drive API for iOS docs do not show any methods for actually uploading a new file to Drive.)
