The views which your create using interface are automatically converted to code including constraints. So it doesn't matter on how you create your views as per the size is concerned, But if you consider usability, readability and maintenance of code interface builder is of much help.

There is another way to reduce app size, which is removing unused code. Here is a tool to detect unused code: WBBlades https://github.com/wuba/WBBlades . It can help you find unused classes in Objc & Swift, so you can safely remove them to reduce app size.
