如何做一个随机数在arc4random_uniform()之间的范围？

所以我的目标在这个码位是随机滚动两个骰子，因为我们都知道你的常规模具只有6面，所以我导入Foundation访问arc4random_uniform(UInt32)。我尝试使用范围(1..7)，以避免随机获取0，但返回一个错误，我不喜欢太多。我试图这样做：

dice1 = arc4random_uniform(UInt32(1..7))

然而，返回

Could not find an overload for ‘init’ that accepts the supplied arguments

我希望这是足够的信息，你惊人的debs在那里帮助我:)

请注意，我只是在操场上练习快速。我不是必须学习如何做到这一点;它只是我修补，我才开始构建实际的应用程序：D

//imports random number function
import Foundation
//creates data storage for dice roll
var dice1: UInt32 = 0
var dice2: UInt32 = 0
//counter variable
var i = 0
//how many times snake eyes happens
var snakeeyes = 0
 //how many times a double is rolled
var `double` = 0
//rolls dice 100 times
while i < 100{
    //from here
    //sets dice roll

这返回一个错误’Range $ T3’不能转换为UInt32

06002

//checks for snake eyes
    if dice1 == 1 && dice2 == 1 {
        snakeeyes = snakeeyes + 1

    }
    //checks for doubles
    if dice1 == dice2{
        `double` = `double` + 1
    }
    //increases counter
        i = i + 1
    //to here
}
println("You got Snake Eyes (snakeeyes) times.")
println("You got Doubles,(`double`) times.")

dice1 = arc4random_uniform(6) + 1;

int random = arc4random_uniform(20) + 10;
