Check if optional array is empty

Question

In Objective-C, when I have an array

NSArray *array;

and I want to check if it is not empty, I always do:

if (array.count &         


        

Answer 1

Conditional unwrapping:

if let anArray = array {
    if !anArray.isEmpty {
        //do something
    }
}

EDIT: Possible since Swift 1.2:

if let myArray = array where !myArray.isEmpty {
    // do something with non empty 'myArray'
}

EDIT: Possible since Swift 2.0:

guard let myArray = array where !myArray.isEmpty else {
    return
}
// do something with non empty 'myArray'
