SetInterval Implmentation

gistfile1.swift

// using the setTimeout implementation https://gist.github.com/jearle/6bfe6153a2e36139ef5c

public func setInterval(#seconds: Double, callback: CancelFunc) -> EmptyFunc {
    
    return setTimeout(seconds: seconds) {
        
        callback(setInterval(seconds: seconds, callback))
        
    }
    
}

// Example

var count = 0

let cancel = setInterval(seconds: 1) { (cancel)->() in
    
    count++
    println("i will fire every 1 second, until count equals 4")
    
    if count == 4 {
        cancel()
    }
    
}

// cancel()
