How do I display the altitude of the user in swift? - swift

Question

I'm trying to build an app that displays the altitude of the user, but xCode says that CLLocation doesn't have member 'altitude'. The code I'm using is
func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) { self.Altitude.text = String(locations.altitude)}

Answer 1

Xcode does not say "CLLocation" has no member 'altitude'" but "[CLLocation] has no member 'altitude'".
locations is an array of CLLocation objects and (as it is an array) does not have a property named altitude.
What you need to do is extract one value from the array and use that to access the altitude.
You probably want to do something like this:
func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
guard let altitude = locations.last?.altitude else { return }
self.Altitude.text = String(altitude)
}
Since this is a user facing string you should format it properly using a LengthFormatter.
A small style note: variable names (like self.Altitude should be lowercased, only types are PascalCase).

Answer 2

You can get Altitude from reverse geocoding in swift for this you can use locationManager and locationManager didUpdateLocations method.
Step 1: Add below Code in ViewdidLoad method:-
let locationManager = CLLocationManager()
locationManager.headingFilter = 1
locationManager.delegate = self
locationManager.startUpdatingHeading()
Step 2: Use didUpdateLocations Method:-
func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
guard let altitude = locations.last?.altitude else { return }
}
