Goals

Update Xcode from 10.2 to 11 Beta (seed 2)

Expected Results

My app runs just as before the update

Actual Results

Realm is causing an thread exception that surfaces on Xcode as:

#7	0x0000000100a4d4dc in realm::object_name(realm::Table const&) at /node_modules/realm/src/object-store/src/list.cpp:72

Specifically:

70 static StringData object_name(Table const& table)
71 {
72     return ObjectStore::object_type_for_table_name(table.get_name());
73 }

I see the following in Xcode's output console:

dynamic_cast error 1: Both of the following type_info's should have public visibility. At least one of them is hidden. N5realm5ArrayE, N5realm12ArrayIntegerE.
/Users/realm/workspace/realm_realm-core_release_5.23.2/src/realm/table.hpp:1774: [realm-core-5.23.4] Assertion failed: dynamic_cast<Parent*>(parent)

Steps to Reproduce

The above exception occurs when trying to push to an array as follows

Code Sample

  // This returns the contact using realm.objectForPrimaryKey
  let contact = getContact(contactId); 
  if (contact.notes.length === 0) {
    realm.write(() => {
      //  *** Breaks here ***
      contact.notes.push({
        contactId: contactId,
        notes: [],
      });
    });
  }

Simplified schema:

export const Contact = {
  name: 'Contact',
  primaryKey: 'id',

  properties: {
    id: {type: 'string'},
    notes: {type: 'list', objectType: 'Notes'},
  }
};

export const Notes = {
  name: 'Notes',
  primaryKey: 'contactId',
  properties: {
    contactId: {type: 'string'},
    notes: {type: 'list', objectType: 'Note'},
  }
};

export const Note = {
  name: 'Note',
  primaryKey: 'id',
  properties: {
    id: {type: 'string'},
    createdTimestamp: {type: 'int'},
    note: {type: 'string'},
    sync:{type:'Sync'},
    owner: {type: 'linkingObjects', objectType: 'Notes', property: 'notes'},
  }
};
