Swift how to sort array of custom objects by property value

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 : [imageFile] = []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)

Swift 2

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

Swift 3 & 4

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

The example above gives desc sort order
