GTLRDrive_File object missing modifiedTime and createdTime properties

Question

I'm working with the Google API Client for REST Swift SDK, and I'm trying to parse out modifiedTime and createdTime from the API response containing GTLRDrive_File objects.

But they don't appear to be there? Here's an example of the payload I'm getting from po file:

GTLRDrive_File 0x60c00084eb20: {
    mimeType:"audio/mpeg"     
    id:"1xt8eqYit3tOrZUeuG9V7_dsq60Iq9xVC" 
    kind:"drive#file" 
    name:"Lobo_Loco_-_15_-_Save_the_Bees_ID_817 (2).mp3" 
}

What's going on? I wouldn't expect these properties to be optional?

Here's the code I'm using to loop after querying:

if let files = result.files as? [GTLRDrive_File] {
    for file in files {
        print(file.modifiedTime, file.createdTime)
    }
}

(And of course both are nil).

How can I get modified/created dates from a GTLRDrive_File?

Answer 1

Provided the request (file.list, etc) was successful createdTime, modifiedTime which can be found in the Drive File Resource, can be accessed by first accessing 'files' object.

So if you go to Try-it:

Use files(createdTime) as parameter in the 'field' property and it will return those fields. (Use files.list as sample).

In the iOS SDK, simply:

let query = GTLRDriveQuery_FilesList.query()
query.fields = "files(createdTime,modifiedTime)"

will work.
