I can say that iOS development and custom backend development work hand in hand. When I was building my app, iOS development focused on creating a smooth and visually appealing user experience. At the same time, the custom backend ensured that all the data processing, user authentication, and integrations with other systems worked flawlessly.
For example, my custom backend handled tasks like syncing user data across devices, securely storing app content, and processing real-time updates. This made the iOS app faster and more reliable because the backend was designed to meet its requirements. In my experience, having a strong custom backend was critical to making the app scalable and delivering a great user experience on iOS.
