There is a birthday field in my RealmObject class which is a type of Int?
. I need to change this field's type to Long?
. I don't know whether I would need a migration or not.
From realm docs :
The integer types byte, short, int, and long are all mapped to long within Realm.
I have tried to install a version of the app without deleteRealmIfMigrationNeeded
(meaning that Realm will try to do a migration if needed) on emulator and then changed the field from Int?
to Long?
. No crashes or exceptions. Also when I pulled my realm file from emulator, field's type stayed the same and still is Int?
.
open class Profile : RealmObject() {
@PrimaryKey
var id = ""
var email = ""
var firstName = ""
var lastName = ""
var dateJoined = 0
var gender: String? = null
var birthday: Int? = null // I want to change this to Long?
}
What I am expecting is that I will need no migrations for this scenario. But I don't want to push the update without getting a real answer.
It is confirmed that there is no migration needed for this case. Do I need a migration to change type Int to Long?
