Cast Int to Bool in Swift

Init Bool With Int.swift

extension Bool {
    init<T : IntegerType>(_ integer: T){
        self.init(integer != 0)
    }
}

// Now you can do this
let x = Bool(5)  // true
let y = Bool(-1) // true
let z = Bool(0)  // false

thanks. to be consistent with objective-c bool on negative values must return false.

Thanks for posting this; really great help. It allowed me to randomly initialize a boolean with arc4random_uniform( ) to use in a ternary expression.

I slightly tweaked it to make it more consistent with how ANSI C handles bools:

extension Bool {
    init<T : IntegerType>(_ integer: T) {
        if integer == 0 {
            self.init(false)
        } else {
            self.init(true)
        }
    }
}

Thanks
