class MyClass {
var name: String?
var address: String?
init(name: String, address: String){
self.name = name
self.address = address
}
}
let array = [MyClass(name: "John", address: "USA"), MyClass(name: "Smith", address: "UK"),MyClass(name: "Paul", address: "AUS"), MyClass(name: "Peter", address: "RSA")]
Now how can sort the array by name of MyClass object.
let sortedArray = array.sort { $0.name < $1.name }
This should do the trick.
array.sortInPlace { $0.name < $1.name }
Correct way to implement this is to ensure your custom class conforms to the Comparable protocol and provides the implementations < and == operators. This will enable you to provide custom comparison and make it extensible.
Come up with an extension-
extension MyClass:Comparable{};
func ==(x: MyClass, y: MyClass) -> Bool {
return x.name == y.name //Add any additional conditions if needed
}
func <(x: MyClass, y: MyClass) -> Bool {
return x.name < y.name //You can add any other conditions as well if applicable.
}
Now you can sort your array of object of this custom class like
let sorted = array.sort(<)
