I was able to retrieve JSON data via HTTP requests using Google Calendar API. As an example, here is a code snippet to make a request to retrieve my calendar metadata:
let url = NSURL(string: "https://www.googleapis.com/calendar/v3/calendars/calendarId")
let task = NSURLSession.sharedSession().dataTaskWithURL(url!) {(data, response, error) in
let dataAsNSString = NSString(data: data, encoding: NSUTF8StringEncoding)
// implement your app logic
}
task.resume()
As far as syncing data between your app and Google Calendar, you can implement callbacks to make PUT requests to update via Google Calendar API. As an example, here is a code snippet for a callback function to make a PUT request to sync w/ your Google Calendar:
func updateUserDataToGoogleCalendar(calendarId: String) {
let url = NSURL(string:"https://www.googleapis.com/calendar/v3/calendars/calendarId")
let dataAsString = "sync data"
var data: NSData? = dataAsString.dataUsingEncoding(NSUTF8StringEncoding)
var headers = Dictionary<String, String>() // specify any headers
Http().put(url!, headers: headers, data:data!) { (result) in
if result.success {
if let json: AnyObject = result.jsonObject {
// implement your app logic
}
}
}
There are numerous Swift HTTP wrapper libraries available. In my example, I am using Swift HTTP.
