Identifiable Information in WWDC 2024 Sessions

Several sessions at WWDC 2024 discussed the use of unique identifiers in various contexts. Here are some key points:

  1. MapKit:

    • Place ID: Introduced as a unique identifier for places, which can be used to reference places represented by map items in the MapKit framework and by place in MapKit JS. These identifiers are unique and remain valid over time, making them useful for persisting and sharing data.
    • Unlock the power of places with MapKit (00:00:56)

  2. TipKit:

    • Custom Identifiers: Allows tips to be reused based on their content. Custom identifiers can be based on concrete elements like user IDs or trail names, enabling TipKit to make tips eligible based on events across multiple app launches.

  3. Core Spotlight:

    • Unique Identifiers: When creating a CS searchable item, a unique identifier should be stored in your app's persistent storage solution to recover the full item data.
    • Support semantic search with Core Spotlight (00:02:13)

  4. FinanceKit:

    • Account Identifiers: Each account has a local unique identifier, which is also present in every transaction and balance, making it easy to associate these objects with their containing account.

  5. App Intents:

    • Uniform Type Identifiers: Used to label files or data with a type, making entities meaningful to the device and allowing for standardized data sharing.

  6. SwiftData:

    • Unique Macro: A new schema macro that allows you to construct a compound constraint on persistent models, ensuring that combinations of model properties remain unique.

  7. AdAttributionKit:

    • Marketplace Identifier: Carries the identifier of the marketplace where the conversion occurred, such as the Apple App Store.

These sessions highlight the importance of unique identifiers in various frameworks and tools, ensuring data integrity, reusability, and meaningful integration across different components of an app.
