This is a demo app I built while reading the book iOS 17 Programming for Beginners. I combined the code so that it supports iPhone and iPad with widgets and Apple Vision Pro with 3D models.  

This is the first complete iOS App I have ever built. Therefore, this codebase will serve as a playground for me to reshape it into something different further.  

This app allows the submission of journal entries with titles, body text, 5-star ratings, pictures, and locations. It provides a dynamic list view that supports search and deletion and can adjust the number of columns on large screens. The saved journal entries can be displayed as a lock screen or home screen widget. There is also a Map View screen presenting the journal entries as pins on the map, according to the location attached to the entries. When launching the app on Apple Vision Pro, a 3D earth model is shown in front of the UI.  

The following skills and techniques were applied when building this app:

• Storyboard navigation and UI layout
• Swift and MVC architecture
• Core Location for obtaining device location
• Map view and POI handling
• Data persistence using JSON
• Custom View
• Camera, photo picker and image file handling
• Search
• Collection View for handling different screen sizes
• Lock screen and home screen widgets using SwiftUI
• VisionOS support, with 3D objects for the VisionOS app variant
• Code linting using SwiftFormat

Obviously, this app lacks proper automated linting, CI/CD, and tests. The UI can be polished further, too. There are things in this App I have coded without understanding how they work, and there can be a lot to follow up on. It all depends on my availability and priority to further work on this repository, but definitely there is a plan.
