在声明变量时,我收到错误"在模式中缺少类型注释",如下所示:

var total

什么是类型注释？

let interestingNumbers = {
            "Prime": [2,3,5,7,11,13],
            "Fibonacci": [1,1,2,3,5,8],
            "Square": [1,4,9,16,25],
        }
        var largest = 0
        var largestKind = "Prime"
        for (kind, numbers) in interestingNumbers {
            var isThisKindLargest = false
            for number in numbers{
                if number > largest {
                    largest = number
                    isThisKindLargest = true
                }
            }
            if isThisKindLargest {
                largestKind = kind
            }
        }
        print(largest)
        print(largestKind)

一行上的连续陈述必须用';'分隔 这个错误由​​Xcode-beta 7.1给出
