GoogleMaps / GooglePlaces leaks memory on iPhone - swift - ios

Question

I'm currently encountering a problem within my app. I have a view on which I can search and select a place with the GoogleMaps / GooglePlaces SDK. I'm also using Google Autocomplete for completing the search string.
The problem: When I visit the first view, everything is still fine, but after I have entered a search string and press search, my memory usage increases for about 10-20 MB. When I unwind the view and save it, the memory won't be released and is still in my total memory. Therefore if I save a couple of places I'll get an overflow and the App will crash.
Do you guys know where my problem is in the code? I'm already searching for hours...
I looked for Database request which sets up listeners but in fact nothing happens regarding this in these classes. Maybe it has something to do with Googlemaps, that it keeps up the connection?
I attached 2 screenshots from my app and the 2 classes for these are the following:
import UIKit
import GoogleMaps
class AddNewPlaceViewController: UIViewController, UISearchBarDelegate, LocateOnTheMap {
//Outlets
#IBOutlet weak var googleMapsContainer: UIView!
//Variables

var resultsArray = [String]()
//Result
var locationAsCoords = [String:Double]()
var locationAdress = String()
//Error
var alerts = Alerts()
var alertActions = AlertActions()
override func viewDidLoad() {
super.viewDidLoad()
}
override func viewDidAppear(animated: Bool) {
super.viewDidAppear(true)
self.googleMapsView = GMSMapView(frame: self.googleMapsContainer.frame)

showSearchBar()

// Error message if no address has been searched
NSLog("Event address ist empty.")
let alert = alerts.alertNoLocationAddress
let alertCancel = alertActions.alertActionCancel
if(alert.actions.count == 0){
alert.addAction(alertCancel)
}
self.presentViewController(alert, animated: true, completion: nil)
} else {
// exits with the saveAndUnwind segue
self.performSegueWithIdentifier("saveAndUnwind", sender: self)
}
}
