SwiftUI Picker

SwiftUI Picker

SwiftUI provides a variety of pickers that can be used to select values from a list. Here are some relevant details from the WWDC 2024 sessions:

1. Subscription Picker API:

   • The subscription picker expects two closures. The first closure returns the view representing each subscription option, and the second closure provides a view for subscribing to the selected plan.
   • You can create custom SwiftUI views for the picker options and use the new subscribe button API.
   • For more details, you can refer to the session What’s new in StoreKit and In-App Purchase.

2. General Picker Usage:

   • Pickers are used to select one value from a list and can be customized extensively.
   • SwiftUI's declarative and adaptive views, including pickers, pack a lot of functionality in just a few lines of code.
   • For a broader overview of SwiftUI controls, including pickers, you can check out the session SwiftUI essentials.

3. Transaction Picker in FinanceKit:

   • The transaction picker API is similar to the photo picker API and is used for selecting financial transactions.
   • It is straightforward to present and use, making it ideal for apps that need selective access to financial data.
   • For more information, see the session Meet FinanceKit.
