Realm: Swift `let` property cannot be marked as dynamic -

i using xcode 7.2, swift 2.1.1. have realm model object below

class b: object {     dynamic let lists = list<a>()  } 

but swift compiler gives me error saying:

property cannot marked dynamic because type cannot represented in objective-c

i saw realm's documentation says:

realm model properties need dynamic var attribute in order these properties become accessors underlying database data.

there 2 exceptions this: list , realmoptional properties cannot declared dynamic because generic properties cannot represented in objective-c runtime, used dynamic dispatch of dynamic properties, , should declared let

but declaring let doesn't seem solve case now. missing?

the documentation quoted includes following (emphasis mine):

list , realmoptional properties cannot declared dynamic because generic properties cannot represented in objective-c runtime, […], , should declared let.

this means property should declared so:

let lists = list<a>() 

the realm swift documentation gained property declaration cheatsheet clarifies requirements different types of declarations.
