How to build a draggable bottom sheet with a scroll view in SwiftUI
This blog post teaches you to create a draggable bottom sheet with a scroll view, similar to those found in Apple Maps or Google Maps.
It leverages SwiftUI's sheet combined with presentationDetents including state management, swipe dismissal prevention, state configuration, and background interaction handling.
Key Features:
- Multiple sheet states (collapsed, medium, expanded)
- Seamless interaction with both sheet content and parent view
- Integrated dragging for smooth content exploration
Benefits:
- Simple code implementation for complex functionality
Downsides:
- Sheets cover the entire view hierarchy, including tab bars (no current workaround within SwiftUI sheets).

Guide to Naming SwiftUI Components
This blog post offers a simple yet powerful way to improve your SwiftUI code readability: ditch the generic "View" suffix!
The Problem: Ever find yourself constantly opening files just to understand their purpose based on a name like "TransactionView"?
The Solution: Replace the "View" suffix with the actual root view used within the component. This creates descriptive names like "TransactionCategoryImage" or "TransactionCostLabel".
By adopting this simple practice, you'll write cleaner, more maintainable SwiftUI code that's easier for you and others to understand.
Make a SwiftUI App with In-App Purchases and Subscriptions using StoreKit 2
This blog post guides you through implementing in-app purchases and subscriptions using StoreKit 2 in a SwiftUI app.
Key takeaways:
- Use StoreKit 2 for modern IAP in your iOS/iPadOS apps.
- Define purchasable items in a StoreKit configuration file.
- Fetch products and verify purchases before updating your app's state.
- Listen for transaction updates to handle things like renewals.
- Restore purchases and create informative renewal strings for subscriptions.
The API is precise, modern and easy to use. StoreKit 2 has come a long way from Apple's initial StoreKit APIs, and you can even use them together with StoreKit 2.
