在 Swift 3 中打印 [英] Print in Swift 3

问题描述

我想知道这两种在 Swift 中打印对象的方式有什么不同.结果似乎相同.

i would like to know what's the different between these two way to print the object in Swift. The result seems identical.

var myName : String = "yohoo" 
print ("My name is \(myName).")

print ("My name is ", myName, ".")

推荐答案

功能上几乎没有区别，逗号只是在字符串前后输入一个空格.

There is almost no functional difference, the comma simply inputs a space either before or after the string.

let name = "John"

// both print "Hello John"
print("Hello", name)
print("Hello \(name)")
