Swift: different objects in one array?

Question

Is there a possibility to have two different custom objects in one array?

I want to show two different objects in a UITableView and I think the easiest way

If you know the types of what you will store beforehand, you could wrap them in an enumeration. This gives you more control over the types than using [Any/AnyObject]:

enum Container {
  case IntegerValue(Int)
  case StringValue(String)
}

var arr: [Container] = [
  .IntegerValue(10),
  .StringValue("Hello"),
  .IntegerValue(42)
]

for item in arr {
  switch item {
  case .IntegerValue(let val):
    println("Integer: \(val)")
  case .StringValue(let val):
    println("String: \(val)")
  }
}

Prints:

Integer: 10
String: Hello
Integer: 42
