Goals

Create predicate within the String argument of the filter method. Without the need to create a NSPredicate instance.

Expected Results

Actual filtered results, based on the predicate.

Actual Results

*** Terminating app due to uncaught exception 'Invalid value', reason: 'NSArray object must contain exactly two objects for BETWEEN operations'

Steps for others to Reproduce

Run a query using the following NSPredicate string and array as options:
`
let dateRange = [date1, date2]
let test = Realm.objects(RealmObject.self).filter("startTime BETWEEN %@", dateRange)
`

Code Sample

Actual method crashing : Link to Method

void QueryBuilder::add_between_constraint(const ColumnReference& column, id value) {
    if (column.has_any_to_many_links()) {
        auto link_column = column.last_link_column();
        Query subquery = get_table(m_group, link_column.link_target_object_schema()).where();
        QueryBuilder(subquery, m_group, m_schema).add_between_constraint(column.column_ignoring_links(subquery), value);

        m_query.and_query(link_column.resolve<Link>(std::move(subquery)).count() > 0);
        return;
    }

    id from, to;
    validate_and_extract_between_range(value, column.property(), &from, &to);

    RLMPropertyType type = column.type();

    m_query.group();
    add_constraint(type, NSGreaterThanOrEqualToPredicateOperatorType, 0, column, from);
    add_constraint(type, NSLessThanOrEqualToPredicateOperatorType, 0, column, to);
    m_query.end_group();
}

Workaround:

Pass the first object of the array, since it's the one that contains the actual variables array. It's not been tested throughout, maybe it's causing other errors.
validate_and_extract_between_range(value[0], column.property(), &from, &to);
