Swift 3: crash to "as! CLGeocodeCompletionHandler"

[aornano]

the fileprivate func geoCodeAddress(_ address:NSString){} caused an error due to a

warning: could not load any Objective-C class information from the dyld shared cache. This will significantly reduce the quality of type information available.

To correct it , it's enough to correct this line:

geocoder.geocodeAddressString(address as String, completionHandler: ({(placemarks: [CLPlacemark]?, error: NSError?) -> Void in

to:

geocoder.geocodeAddressString(address as String, completionHandler: ({(placemarks: [CLPlacemark]?, error: Error?) -> Void in

You can find more details also here in SO

You also don't need to force casting to as! CLGeocodeCompletionHandler, so it can be removed.
