- Swift 6 introduces typed throws for type-safe error handling.
- Custom SystemError protocol enhances error handling with log and user-friendly messages.
- Error hierarchy and diagnostics are supported through underlyingErrors and lookup functions.
- Default implementations simplify error handling with structured messages and diagnostics.
- Both struct and enum can be used as error types with SystemError protocol.
- NSError and DecodingError extensions integrate with SystemError for better diagnostics.
- Typed throws syntax (throws(MyErrorType)) specifies error types functions can throw.
- Error handling examples demonstrate structured error messages and diagnostics.
- Lookup functions help identify specific error types within the error hierarchy.
- Structured error stacks improve debugging and user feedback.
