Swift - Extra Argument in call

Question

I am trying to call a function declared in ViewController class from DetailViewController class.

When trying to debug the \'Extra Argument in call\" error pops up.<

Answer 1

In latest Swift 2.2, I had a similar error thrown which took me a while to sort out the silly mistake

class Cat {
    var color: String
    var age: Int

    init (color: String, age: Int) {
        self.color = color
        self.age = age
    }

    convenience init (color: String) {
        self.init(color: color, age: 1){ //Here is where the error was "Extra argument 'age' in call
        }
    }
}


var RedCat = Cat(color: "red")
print("RedCat is \(RedCat.color) and \(RedCat.age) year(s) old!")

---

The fix was rather simple, just removing the additional '{ }' after 'self.init(color: color, age: 1)' did the trick, i.e

 convenience init (color: String) {
        self.init(color: color, age: 1)
  }

which ultimately gives the below output

"RedCat is red and 1 year(s) old!"
