Difference between sort and sortInPlace in swift 2?

Question

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.

Please explain the d

Answer 1

FWIW, in Swift 3 there is no sortInPlace. instead there is a sort & sorted.

var mutableArray = [19, 7, 8, 45, 34]

mutableArray.sortInPlace() // error : 'sortInPlace()' has been renamed to 'sort()'

mutableArray.sort() // 
print(mutableArray) // [7, 8, 19, 34, 45]

mutableArray.sorted()

print(mutableArray) // [19, 7, 8, 45, 34]
let anotherArray = mutableArray.sorted()

print(anotherArray) // [7, 8, 19, 34, 45]

If you want to use sortInPlace or sort which are mutating functions then the array must be a var, otherwise you could get a misleading error saying:

'sort()' has been renamed to 'sorted()'
