Realm的坑（二）

realm_Foo.swift

class Foo:Object {
    dynamic var id:Int = 0
    dynamic var name:String = ""
    
    override class func primaryKey() -> String? {
        return "id"
    }
}

let bar = Foo()
bar.id = 1
bar.name = "Marry" // ok

let realm = try! Realm() 
try! realm.write {
    realm.add(bar)
    bar.name = "Kelly" // ok
}
  
let anotherBar = Foo()
anotherBar.id = 1
anotherBar.name = bar.name
  
try! realm.write {
    realm.add(anotherBar, update:true)
}
