How to check what class belongs AnyObject?

问题

For example, there are two models Realm Information

    import Foundation
    import RealmSwift

    class Music: Object {

        dynamic var id = ""
        dynamic var title = ""
        dynamic var url = ""
    }
    class DownloadMusic: Object {

        dynamic var id = ""
        dynamic var title = ""
        dynamic var path = ""
    }

And there is a certain function

func test(object: AnyObject) {

}

When a call is transferred as an argument 'realm.objects(Music)[0]'

let realm = try! Realm()    
test(realm.objects(Music)[0])

Can I check in function, the object belongs to a class 'Music' or to a 'DownloadMusic'

回答1:

Try this:

func test(object: AnyObject) {
    if object is Music {
        print("music")
    } else if object is DownloadMusic {
        print("downloadmusic")
    }
}
