Use of unresolved identifier 'MapTasks' in Swift - objective-c

Question

I am following tutorial, as it is pretty old tutorial and they actually used GoogleMaps framework package instead of pods which I followed and everything was going smooth till I reached Spotting a Custom Location. In that section they asked to update func geocodeAddress as below, and add var mapTasks = MapTasks() in ViewController.swift file which I did but it gives me error.
Use of unresolved identifier 'MapTasks'
error
func geocodeAddress(address: String!, withCompletionHandler completionHandler: ((status: String, success: Bool) -> Void)) {
if let lookupAddress = address {
var geocodeURLString = baseURLGeocode + "address=" + lookupAddress
geocodeURLString = geocodeURLString.stringByAddingPercentEscapesUsingEncoding(NSUTF8StringEncoding)!
let geocodeURL = NSURL(string: geocodeURLString)
dispatch_async(dispatch_get_main_queue(), { () -> Void in
let geocodingResultsData = NSData(contentsOfURL: geocodeURL!)
var error: NSError?
let dictionary: Dictionary<NSObject, AnyObject> = NSJSONSerialization.JSONObjectWithData(geocodingResultsData!, options: NSJSONReadingOptions.MutableContainers, error: &error) as Dictionary<NSObject, AnyObject>
if (error != nil) {
println(error)
completionHandler(status: "", success: false)
}
else {
// Get the response status.
let status = dictionary["status"] as String
if status == "OK" {
let allResults = dictionary["results"] as Array<Dictionary<NSObject, AnyObject>>
self.lookupAddressResults = allResults[0]
// Keep the most important values.
self.fetchedFormattedAddress = self.lookupAddressResults["formatted_address"] as String
let geometry = self.lookupAddressResults["geometry"] as Dictionary<NSObject, AnyObject>
self.fetchedAddressLongitude = ((geometry["location"] as Dictionary<NSObject, AnyObject>)["lng"] as NSNumber).doubleValue
self.fetchedAddressLatitude = ((geometry["location"] as Dictionary<NSObject, AnyObject>)["lat"] as NSNumber).doubleValue
completionHandler(status: status, success: true)
}
else {
completionHandler(status: status, success: false)
}
}
})
}
else {
completionHandler(status: "No valid address.", success: false)
}
}
Here is my GitHub repository
Thank you in advance.

If you fully read that tutorial, you will find in the instruction that you need to create a file name MapTasks which is a class.
You can just copy this file from GitHub and add it to your project.
