The reason being, you cannot have 2 "viewControllers" on screen at the same time with the exception of Controllers of Controllers (Tab Bar, Navigation, SplitView). You are trying to put one view controller in another view controller right now. | [

I have a hash collection:
`my_hash = {"1" => "apple", "2" => "bee", "3" => "cat"}`
What syntax would I use to replace the first occurrence of the `key` with hash collection `value` in a string?

`str = I want a 3`
The resulting string would be:
`str = I want a cat`

OkWorld()` works fine.
How do you verify that `OkWord` exists without deceleration ?
**Edit 1**
I know that `OkWorld` is an `alias` but its a reference to `servers\testing\HelloWord` which is a valid class ...

But the interpreter will not search the strings, so the function `class_exists` will get the string `OKWorld` and search for the corresponding class, which doesn't actually exist!
