ios - RLMException: Can't persist property 'id' with incompatible type, but nonexistant -

i'm trying new instance of object:

class myawesomerealmobject: baserealmobject {      var field:     string = ""     var thing:     string = ""     var whatever:  string = ""     var something: string = ""     var key:       string = ""      var cards = [otherrealmobject]()//wasnt either      override static func primarykey() -> string? {         return "key"     }  //    override static func ignoredproperties() -> [anyobject] { //        return ["id"] //this didnt work either //    }  } 

this parent class

class baserealmobject: object {     //nothing here, extending realm's object } 

and runtime exception.

i don't event have field name 'id'. i've added ignoredproperties(), not sure else do.

edit: happens without fields on entity

i tried adding dynamic modifier, didn't work. troubleshooting more, blew away fields.

class myawesomerealmobject: rlmobject {  } 

and still runtime exception regarding 'id'.

edit 2: more information exception

i'm wondering if shed light on it

rlmrealmcoreversion = unknown. hmmm

it turned out realm parses of entities in model in lazy way. 'id' error because entity had id of type uint, unsupported.

i changed field on different entity type int, supported realm.

now getting errors other fields, @ least know now.
