Positive Number In Array: Buggy Code in Swift

Inside the code editor we've tried to write a function that takes an array nums as argument and returns true if there exists at least one positive (greater than zero) number in the array; returns false otherwise.

So when we called the function for [-1, 2, 3], we expected our code to print:

Array has positive numbers

but it seems like we made some mistakes because the Swift compiler rejects our code with:

error: missing return in global function expected to return 'Bool'

Assignment:

Your task is to fix our function.
