问题描述
我一直试图快速使用sortInPlace函数，但是它不起作用.当我使用sort函数而不是sortinplace时.
I have been trying to use the sortInPlace function in swift but it is not working. When I use the sort function instead of sortinplace it works.
请说明这两个功能之间的区别.如果您可以提供小代码示例来演示这两个功能的使用，那将非常有帮助.
Please explain the difference between these 2 function. It would be very helpful if you can provide small code sample demonstrating the use of both functions.
推荐答案
var mutableArray = [19, 7, 8, 45, 34]
// function sort sorts the array but does not change it. Also it has return
mutableArray.sort()
mutableArray
// prints 19, 7, 8, 45, 34
// function sortInPlace will mutate the array. Do not have return
mutableArray.sortInPlace()
mutableArray
// prints 7, 8, 19, 34, 45
