Hi,
Im tying to use a variable outside of a function, I've searched many different solitons and none seem to work 😟
func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
let location = locations[0]
/
let Speed = location.speed * 2.236936284
SpeedLabel.text = "\(Speed)"
}I wish to use the variable "Speed" elsewhere in my program.. How can this be done?
Any help is appreciated
Thanks
Oliver
func locationManager is defined in a controller, most probably.
If so, just declare a var at the controller class level
var speed = Float(0)and set it in the func:
func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
let location = locations[0]
speed = location.speed * 2.236936284
speedLabel.text = "\(speed)"
}Note that var names should begin with lowercase, by Swift convention.
You could also declare
var speed : Float?To know wether or not the value has been set.

Thank you Claude!
This soluton worked great for me
