Question 1

How to save images to disk using Disk?

Accepted Answer

Use Disk.save() with a UIImage and specify the directory, like saving to .documents as 'Album/nature.png'. The README provides code examples for saving single images or arrays to folders.

Question 2

Disk vs Core Data: which one should I use for my iOS app?

Accepted Answer

Disk is best for simple file persistence of Codable data, images, or raw data, following Apple's storage guidelines. Core Data is better for complex data models with relationships, querying, and change tracking. Disk is lighter and faster for basic tasks.

Question 3

How to handle errors with Disk in Swift?

Accepted Answer

Disk throws detailed errors, so use do-catch blocks. The README shows an example with NSError properties like localizedDescription and recovery suggestions for debugging file system issues.

Question 4

Can Disk be used for caching network responses?

Accepted Answer

Yes, Disk is ideal for caching Codable structs from network responses to directories like .caches. The README demonstrates saving and retrieving JSON data as custom types with minimal code.

Question 5

How to append data to an existing file with Disk?

Accepted Answer

For Codable structs, use Disk.append() to add data to a JSON file, but note it requires decoding and re-encoding. For images or Data, appending creates new files with auto-generated names in a folder.

Question 6

Is Disk compatible with SwiftUI?

Accepted Answer

Yes, Disk works with SwiftUI as it's a Swift library for iOS. However, since it's synchronous, you should wrap operations in async tasks or DispatchQueue to prevent blocking the UI thread.
