Question 1

How do I cache JSON data with CachyKit?

Accepted Answer

Use CachyLoader's loadWithURL method with a JSON URL; it caches the data asynchronously, and you can process it in the completion block. Ensure the data conforms to supported types, as CachyKit handles various objects including JSON.

Question 2

CachyKit vs SDWebImage for caching images?

Accepted Answer

CachyKit offers general-purpose caching with image extensions, while SDWebImage is highly optimized for images with features like progressive loading. Choose CachyKit if you need caching for multiple data types; SDWebImage for image-specific performance.

Question 3

How to set up disk caching in CachyKit?

Accepted Answer

Configure CachyLoaderManager.shared with isOnlyInMemory set to false and specify diskCapacity in the configure method. This enables hybrid caching where objects persist on disk after memory limits are exceeded.

Question 4

Does CachyKit support background fetching for updates?

Accepted Answer

It supports force refreshing via isRefresh parameter to fetch fresh data, but doesn't explicitly handle iOS background modes; you'd need to integrate background tasks separately for system-level execution.

Question 5

How to handle cache expiration for specific objects?

Accepted Answer

When adding objects, use CachyObject with a custom expirationDate, such as ExpiryDate.seconds(3600) for one-hour expiry. This allows fine-grained control over when individual cache items expire independently.

Question 6

Can I use CachyKit with SwiftUI?

Accepted Answer

Yes, but UIImageView extensions are UIKit-specific. Use the underlying Cachy or CachyLoader components to cache data, and bridge to SwiftUI's Image view manually, as no direct SwiftUI extensions are provided.
