Trying to update CLLocation if NSUserDefault Exists in Swift - ios

Question

Originally I was trying to save a CLLocation as a NSUserDefault value before I stored it as a CKRecord in CLoudkit but I got the error: "defaults.setObject(locationRecord.recordID, forKey: "locationRecordID")" with the reason being "Attempt to set a non-property-list object as an NSUserDefaults/CFPreferences value for key locationRecordID". So now I am trying to save the lat and long as a default and replace the old location in Cloudkit. I am currently getting a 'Thread 1 SIGABRT' error on the line "publicDB.fetchRecordWithID((defaults.objectForKey("Location") as! CKRecordID),completionHandler: " with the reason being "Could not cast value of type '__NSCFDictionary' (0x1a1bec968) to 'CKRecordID'."
func locationManager(manager: CLLocationManager, didUpdateLocations locations: [CLLocation])
{
let location = locations.last
self.loc1 = location!
let center = CLLocationCoordinate2D(latitude: location!.coordinate.latitude, longitude: location!.coordinate.longitude)
let region = MKCoordinateRegion(center: center, span: MKCoordinateSpan(latitudeDelta: 0.004, longitudeDelta: 0.004))
self.mapView.setRegion(region, animated: true)
self.locationManager.stopUpdatingLocation()
self.locationManager.startMonitoringSignificantLocationChanges()
self.getRecordToUpdate(locations)
let lat: CLLocationDegrees = center.latitude
self.lat1 = lat
let long: CLLocationDegrees = center.longitude
self.long1 = long
locationRecord.setObject(location, forKey: "location")
let publicData = CKContainer.defaultContainer().publicCloudDatabase
publicData.saveRecord(locationRecord) { record, error in
}
if error == nil
{
print("Location saved")
}
}
func getRecordToUpdate(locations:[CLLocation])
{
let defaults = NSUserDefaults.standardUserDefaults()
var locationRecord:CKRecord
if defaults.objectForKey("Location") == nil{
locationRecord = CKRecord(recordType: "location")
let locationDict = ["lat": lat1, "lng": long1]//
defaults.setObject(locationDict, forKey: "Location")//
self.updateLocationRecord(locationRecord, locations: locations)
print("new")
}else{
let publicDB = CKContainer.defaultContainer().publicCloudDatabase
publicDB.fetchRecordWithID((defaults.objectForKey("Location") as! CKRecordID),completionHandler: {
(record, error) in
if error == nil{
self.updateLocationRecord(record!, locations: locations)
print("fetched record")
}else{
print("Error fetching previous record")
}
})
}
}
func updateLocationRecord(locationRecord:CKRecord, locations:[CLLocation])
{
let location = locations.last
locationRecord.setObject(location, forKey: "location")
let publicData = CKContainer.defaultContainer().publicCloudDatabase
publicData.saveRecord(locationRecord) { record, error in
}
if error == nil
{
print("Location saved")
}
}

Try this
You can save NSData to NSUserDefaults. So all you need is to convert your CLLocation object to NSData as follow:
// saving your CLLocation object
let locationData = NSKeyedArchiver.archivedDataWithRootObject(your location here)
NSUserDefaults.standardUserDefaults().setObject(locationData, forKey: "locationData")
// loading it
if let loadedData = NSUserDefaults.standardUserDefaults().dataForKey("locationData") {
if let loadedLocation = NSKeyedUnarchiver.unarchiveObjectWithData(loadedData) as? CLLocation {
println(loadedLocation.coordinate.latitude)
println(loadedLocation.coordinate.longitude)
}
}
