How to reuse an Xcode project into a new project? Static library, Framework, Targets?

I built an iOS project (actually workspace because of Pods) that is 100% functional, with its logic and UI (Storyboard and xibs). Now I would like to reuse this app/project as a "core" for future apps.

I've been searching about it and there are several solutions like Static libraries, Frameworks and Targets. But I am not sure which one would be the best in my case. I would like to reuse all the UI part as well.

I saw that most of the people agree that the best approach for reusing code is static libraries, even thought it looks not so straight forward. But I think for reusing UI probably Targets is the best solution. The problem I see is that if a build 10 apps based on my core project, the new project will be huge, so probably it is not the best option.

I don't know if you guys have any better idea or opinion.

Thanks in advance!!
