Most developers default to a for loop when they must loop through a collection or perform an operation several times. I find that the value of the while loop is often overlooked. It has some advantages over Swift's for loop in some scenarios. In this episode of Swift Fundamentals, you ...
Swift while loop is a loop that is used for performing a condition check and its loop code is also for making the loop work in a repeated fashion until the condition within the loop gets failed. Swift while loop is quite advantageous when the number of iterations is not known before the ...
while 只要给定条件为真,Swift 4 编程语言中的循环语句就会重复执行目标语句。 句法 的语法 while Swift 4 编程语言中的循环是 - while condition { statement(s) } 复制 这里statement(s)可以是单个语句或语句块。这condition可以是任何表达式。当条件为真时循环进行迭代。当条件变为假时,程序控制将传递到紧...
Swift While 循环 Swift 循环 Swift while循环从计算单一条件开始。如果条件为true,会重复运行一系列语句,直到条件变为false。 语法 Swift while 循环的语法格式如下: whilecondition{statement(s)} 语法中的statement(s)可以是一个语句或者一个语句块。condition可以是一个表达式。如果条件为true,会重复运行一系列语句,...

Swift while loop is used to run a specific code until a certain condition is met. The syntax of while loop is: while (condition){ // body of loop } Here, A while loop evaluates condition inside the parenthesis (). If condition evaluates to true, the code inside the while loop is exe...
