I primarily do web dev work and I've been diving deep into React Native recently and have worked with Ionic for a little bit. What I find with these hybrid frameworks is that they aren't perfect. I love React Native. I think it's an incredible piece of technology and the level of accessibility and empowerment it gives web developers to venture into the realm of mobile development is a great thing. But at the same time, there are so many things that React Native cannot take advantage of -- at least, not at the Facebook-developed level (remember, Facebook's RN team is going to focus in on the parts of the framework that they can get the most value out of internally). You're going to miss a lot of things that you would normally take for granted in real native iOS and Android development such as a Camera module (yes, I know!) and OpenGL. There are third party libraries that support these things, but your tradeoff here is that you are going to either become dependent on the maintainers' ability to fix bugs and introduce new features or (if your app becomes the biggest consumer of those libraries) you will become the lead maintainer. RN is still great for letting web developers add components to an existing Swift/Obj-C/Java codebase and I really enjoy using it. However, I think the maintenance and dependency costs of building a larger-scale RN-first app might not be the best idea Regarding Ionic/Phonegap/Other "Write once, run anywhere" frameworks: I feel this is a large UX tradeoff and would never make it. Things don't feel smooth when emulated. I would never use one of these types of frameworks for production purposes.
