如何跳过for-in循环的迭代(Swift 3) [英] How to skip iterations of a for-in loop (Swift 3)

问题描述

在Swift 3中是否可以跳过for-in循环的迭代?

Is it possible to skip iterations of a for-in loop in Swift 3?

我想做这样的事情:

for index in 0..<100 {
    if someCondition(index) {
        index = index + 3 //Skip iterations here
    }
}

推荐答案

简单的while循环即可

Simple while loop will do

var index = 0

while (index < 100) {
    if someCondition(index) {
        index += 3 //Skip 3 iterations here
    } else {
        index += 1
        // anything here will not run if someCondition(index) is true
    }
}
