Array usually represented as List<T>. This allows to handle many-to-many relationship in Realm.

Dictionary is not supported by Realm. But it can be achieve with 2 classes and to-many relationship. For example:

class User: Object {
    dynamic var name = ""
    let stackOverflowQuestions = List<Question>()
}

class Question: Object {
    dynamic var title = ""
    dynamic var message = ""
    // etc.
}
