Initialize class-instance and access variables in Swift

Question

I just created a class and gave it some vars. Unfortunately I can\'t access these variables in my iOS-Projects. However, the same syntax works in playground...<

Answer 1

The last two lines need to be inside a function. You can have only declarations in class scope, not expressions to be executed.

Answer 2

The syntax for a class declaration is:

class <class name>: <superclass>, <adopted protocols> {
  <declarations>
}

Your declaration of ViewController includes rex.age = 2 which itself is not a declaration, it is a statement - specifically a binary expression with an infix operator.
