Issue Description:

Instruments mark this as memory leak:

- (NSArray *)fetchModelsCount:(NSUInteger)count {
    NSMutableArray *arr = [NSMutableArray new];

    for (int i = 0; i < count; i++) {
        NSString *modelName = [NSString stringWithFormat:@"#%i Dummy swift model name.", i+1];
        DummySwiftModel *model = [[DummySwiftModel alloc] initWithName:modelName];
        [arr addObject:model];
    }

    return [arr copy];
}

DummySwiftModel is Swift class.

Example project attached.
