in xcode I could create an instance of Business, but here in compiler in not executing. Will someone assist me?

objects.swift 
struct Location {
  let latitude: Double
  let longitude: Double
}

class  Business
{
let name:String
let location:Location
init (name:String = "arun", latitude:Double= 30.2, longitude:Double= 35.7 )
{
self.name = name
self.location = Location(latitude: latitude, longitude: longitude)

Hi Arun,

Here are your issues:

  1. You are trying to instantiate someBusiness instance inside your class body but it should be in the main body of the program.
  2. When you create the someBusiness instance you are not passing in the values to be initialised (you've hardcoded them in the initialiser).
  3. Your initialiser should take a single instance of Location, not a pair of doubles representing lat and long.
  4. You have an extra space between class and Business

Cheers

Alex
