Simon Grimm, an Ionic Developer Expert, provides a comprehensive guide on transforming an Ionic app into a released iOS app, even for those without prior native app development experience. The guide covers the installation of necessary native tools like Xcode, enrollment in the Apple Developer Program, and the configuration of Capacitor, which allows web applications to access native APIs. It walks through the steps of building the app with Capacitor, creating icons and splash screens, and the process of deploying the app to the Apple App Store. The guide also touches on managing app settings with Trapeze and utilizing Appflow for live updates to streamline the app release process. Grimm emphasizes that while the process might seem daunting, it is more manageable than it appears, and offers additional resources through the Ionic Academy for those looking to deepen their understanding of Ionic app development.
