Dynamic Advanced Properties in Swift 2.0

Question

I saw this post Advanced Dynamic Properties in Swift , but I don't want it to complete the class in NSObject . This applies to the Realm database. I don't need to have nil properties, but it would be nice if I modeled my database. The Realm documentation, which can be found here https://realm.io/docs/swift/latest/ , says the options are supported. Here is my

The code

 dynamic var complete: Bool? = nil 

and here is mine

Mistake

 Property cannot be marked dynamic because its type cannot be represented in Objective-C 

I know this is the same code and error as the message above, but I'm just wondering if the Realm documentation says that it supports it, do they have another job?

Answer 1

In documents of supported types and additional properties .

String , NSDate , NSData and object properties may be optional. Additional numbers are RealmOptional using RealmOptional .

RealmOptional supports Int , Float , Double , Bool and all versions of Int size ( Int8 , Int16 , Int32 , Int64 )).

Thus, options for String , NSDate , NSData and Object supported with standard fast syntax.

For other numeric types (e.g. Bool ) that are executed using RealmOptional . Then, to use a variable of this type, RealmOptional , you access the value property, which is optional, which represents your base value.

 // definition (defined with let) let complete = RealmOptional<Bool>() // defaults to nil // usage complete.value = false // set non-nil value ... complete.value = nil // set to nil again
