Question 1

How do I catch exceptions from NSKeyedUnarchiver in Swift?

Accepted Answer

Use ExceptionCatcher's catch method to wrap the NSKeyedUnarchiver call. It converts any thrown Objective-C exception into a Swift Error that you can handle with do-try-catch, as demonstrated in the README example.

Question 2

Is ExceptionCatcher better than using @try-@catch in Objective-C?

Accepted Answer

ExceptionCatcher is for Swift code; it allows you to catch Objective-C exceptions within Swift without mixing languages. If you're writing Swift, it's the recommended approach over embedding Objective-C syntax.

Question 3

Does ExceptionCatcher work on iOS and macOS?

Accepted Answer

Yes, ExceptionCatcher is compatible with both iOS and macOS as long as you're using Cocoa APIs that throw Objective-C exceptions, since it relies on the Objective-C runtime available on Apple platforms.

Question 4

How to install ExceptionCatcher using Swift Package Manager?

Accepted Answer

Add the package dependency in your Package.swift file with the URL and version specified in the README, or use Xcode's package dependency feature. The installation steps are clearly outlined in the documentation.

Question 5

What are the alternatives to ExceptionCatcher for handling exceptions in Swift?

Accepted Answer

Alternatives include writing custom Objective-C wrappers or using other third-party libraries, but ExceptionCatcher is popular for its simplicity. For pure Swift code, native error handling with Result types is preferred.
