var Password1 : Array = [Int]()
var Password2 : Array = [Int]()
while Password1.count < 800 {
var RandomNum1 = Int(arc4random_uniform(256))
var RandomNum2 = Int(arc4random_uniform(256))
Password1[Password1.count] = RandomNum1
Password2[Password2.count] = RandomNum2
}
在这行Password1[Password1.count] = RandomNum1
出现 -> EXC_BAD_INSTRUCTION (code=EXC_I386_INVOP, subcode=0x0)
