I am new to swift and I am trying to use variables in the CLLocation. When I include the variables it says I need a double. How could I go about this? My code:

//File 1
static var long: String = UserDefaults.standard.string(forKey: "long_key") ?? ""

static var lat: String = UserDefaults.standard.string(forKey: "lat_key") ?? ""

//File 2
let longitude = File1.long

let latitude = File2.lat

let location = CLLocation(latitude: longitude, longitude: latitude)

Welcome.

You have to convert your strings to Double. As conversion may fail (if File1.long is "" for instance), you need to use if let to test for nil:

if let longitude = Double(File1.long), let latitude = Double(File2.lat) {
  let location = CLLocation(latitude: longitude, longitude: latitude)
  // Continue code
}
