ENUM

ArrayBuilder

The ArrayBuilder is a simple result builder that outputs an array of any type.

You can define any array using Swift's DSL:

@ArrayBuilder<String> var string: [String] {
    "Hello, "
    if bool {
        "world!"
    } else {
        "colibri!"
    }
    for x in 0...10 {
        "\nIteration Number \(x)"
    }
}
