Question 1

How does YapDatabase compare to Core Data?

Accepted Answer

YapDatabase offers better out-of-the-box concurrency and caching with a simpler Swift/Objective-C API, but Core Data has deeper Xcode integration and more built-in tooling. YapDatabase is often preferred for performance-focused apps needing fine-grained control.

Question 2

How to set up YapDatabase for concurrent access in Swift?

Accepted Answer

Create multiple database connections using the newConnection() method, and use read/write transactions on background threads to avoid blocking the UI. The README's hello world example demonstrates basic concurrency with separate connections.

Question 3

What are the limitations of YapDatabase?

Accepted Answer

It's restricted to Apple platforms and may not support all SQLite features directly. Additionally, the abstraction layer can add overhead for very simple queries, and custom extensions require more upfront learning.

Question 4

How to implement full-text search with YapDatabase?

Accepted Answer

Use the built-in FTS module by configuring secondary indexes and leveraging the full-text search APIs. The wiki provides examples for setting up efficient searching within your app's data.

Question 5

Can YapDatabase sync with CloudKit easily?

Accepted Answer

Yes, it includes out-of-the-box CloudKit sync support with example projects, such as a syncing Todo app. This makes it straightforward to implement data synchronization across Apple devices without writing custom sync logic.

Question 6

YapDatabase vs Realm for iOS apps?

Accepted Answer

YapDatabase is built on SQLite with a focus on concurrency and caching, while Realm offers a object-oriented database with live queries. YapDatabase may be better for SQLite familiarity, but Realm has cross-platform support and simpler syntax for some use cases.
