A couple helpers for working with optionals

Optionals.swift

import Foundation

func ifOptionalHasValue<T>(optional: T?, then: (T) -> Void) {
    ifOptionalHasValue(optional, { (value) -> Void in
        then(value)
    }) { () -> Void in
        // do nothing
    }
}

func ifOptionalHasValue<T>(optional: T?, then: (T) -> Void, orElse: (() -> Void)?) {
    if let optionalValue = optional {
        then(optionalValue)
    } else {
        if let orElseBlock = orElse {
            orElseBlock()
        }
    }
}
