Subclass your two classes to one protocol, for example

protocol HasName {
    var name: String { get set }
}

class Person: HasName {
    var name: String = ""

    init(name: String) { self.name = name }
}

class Car: HasName {
    var name: String = ""

    init(name: String) { self.name = name }
}

Creating the array would look like this, in this case.

let someArray: [HasName] = [
    Car(name: "mercedes"),
    Person(name: "jason")
]

// you can then now use the `.sort()` array function.

someArray.sort(by: { $0.name > $1.name })

Swift排序不同类的数组
