Swift how to sort array of custom objects by property value

Question

lets say we have a custom class named imageFile and this class contains two properties.

class imageFile  {     var fileName = String()     var fileID = Int() } 

lots of them stored in Array

var images : Array = []  var aImage = imageFile() aImage.fileName = "image1.png" aImage.fileID = 101 images.append(aImage)  aImage = imageFile() aImage.fileName = "image1.png" aImage.fileID = 202 images.append(aImage) 

question is: how can i sort images array by 'fileID' ASC or DESC?

Answer 1

First, declare your Array as a typed array so that you can call methods when you iterate:

var images : [imageFile] = [] 

Then you can simply do:

Swift 2

images.sorted({ $0.fileID > $1.fileID }) 

Swift 3+

images.sorted(by: { $0.fileID > $1.fileID }) 

The example above gives desc sort order
