Conclusion

iOS app development can take very different forms depending on the product behind it. A straightforward consumer app may mainly need strong Swift development and careful UI work, while a banking, healthcare, or enterprise product can quickly turn into a much larger backend, security, integration, and testing project.

The useful comparison is therefore not just who develops for Apple devices. It is how well the development setup matches the actual product: native expertise, architecture, backend requirements, QA, release management, and the ability to keep the application maintainable after launch. For products expected to evolve over several years, those less visible technical decisions tend to matter just as much as the first App Store release.
