Swift - Sorting NSMutableArray with objects in it

Question

I have a fruit object in swift with

var title: String? 
var desc: String?

variables

I have it in a fruitsArray which is an NSMutableArray.

I want to sort out these fruit objects alphabetically depending on their title. I need to do this both ascending and descending.

I have tried doing the following:

 NSSortDescriptor *sortDescriptor =
        [NSSortDescriptor sortDescriptorWithKey:@"title"
    ascending:YES
    selector:@selector(caseInsensitiveCompare:)];
    [fruitsArray sortedArrayUsingDescriptors:@[sortDescriptor]];

But it does not work at all, just heaps of errors.

How do I do this?

Thanks in advance friends.

do you know that the code sample you provide is in Objective-C? — Wain, Apr 08 '16 at 10:18
The code is in swift, not obj-c. So there is no answer for this. — Big Green Alligator, Apr 08 '16 at 11:34

You have to use sort function with a block:

struct Fruit {
    var title: String
    var desc: String
}

var fruits = [Fruit]()
fruits.append(Fruit(title: "a", desc: "b"))
fruits.append(Fruit(title: "c", desc: "d"))


let sorted = fruits.sort() { $0.title > $1.title }
sorted

You might tell him what's the difference. Each has its uses. – gnasher729 Apr 08 '16 at 10:57
