Swift For Loop Thread Error

func randomroll () {

    var time = arc4random_uniform(10)

   while(time < 5)
   {
    time = arc4random_uniform(10)
   }

   for(var time1 = time; time1>=0; time1--) { //This is where I get the thread error
    ...
   }
 }

The error I am getting is Thread 1: EXC_BAD_INSTRUCTION (code=EXC_I386_INVOP, subcode=0x0)

I am a beginner swift programmer and am sure I am missing something obvious, was hoping for some insight. Thank you.

func randomroll() {

    var time = Int(arc4random_uniform(10))

    while(time < 5)
    {
        time = Int(arc4random_uniform(10))
    }

    for time; time >= 0; time-- { //This is where I get thread error
        println(time)
    }
}

randomroll()

time is an Uint32 and can't be negative. So either don't let it become negative or convert it to an Int
