Wrong sort of RealmSwift

This part of code:

var posts: Results<Post> {
    get {
        return realm.objects(Post.self).sorted(byKeyPath: "id", ascending: false)
    }
}

returns ids like

96, 950, 94, 930

My post id is String. How to get right sorted objects without making id Int.

Unfortunately, when sorting via a String property, Realm automatically sorts it alphabetically, instead of numerical sorting.

Adding the ability to manually sort properties via a block/closure is on the roadmap, but there's nothing to announce for it just yet. I recommend you go and '+1' that particular GitHub thread so it can get more priority. :)

The most ideal solution would be to change id to an Int property if you can. Failing that, njzk2's solution of manually sorting the Results into a Swift array 'will' work, but that will page all of the Realm objects into memory at once (causing more overhead), so it's not optimal.
