Steps & Code to Reproduce

Can't share the complete code, but i can share the following

ContactModel:
final class ContactModel: Object, ObjectKeyIdentifiable {

@Persisted(primaryKey: true) var phone: String = ""
@Persisted var code: String = ""
@Persisted var first_name: String = ""
@Persisted var last_name: String = ""
@Persisted var nick_name: String = ""
@Persisted var company_name: String = ""
@Persisted var emp_id: String = ""
@Persisted var pos_id: String = ""
@Persisted var sent: Int64 = 0
@Persisted var is_main: Bool = false
@Persisted var favorite: Bool = false
@Persisted var name: String = ""

}

Trying to insert the data:
let contactSnap = ContactModel().transformSnap(snap: snap)

    contactSnap.name =  contactSnap.first_name.isEmpty ? contactSnap.nick_name : contactSnap.first_name + " " + contactSnap.last_name
    let realm = try! Realm()
    try? realm.safeWrite  {
        realm.create(ContactModel.self,value: contactSnap,update: .modified)
    }
