Bugs
- No significant bugs found in the visible portion of the code.
Optimizations
- Simplify the Codable conformance by making
AttachedImage
conform directly toCodable
instead of using a nested struct for encoding/decoding. - Consider using
URL
type instead ofString
for theurl
property for better type safety and validation.
Good points
- Adheres to Swift's best practices with the use of
public
access control. - Smart use of
Hashable
andSendable
protocols suggesting immutability and safety in concurrent programming contexts. - Clear and straightforward initialization method.
Summary
The AttachedImage
struct is well-designed with a focus on thread safety and immutability, as indicated by its conformance to Sendable
and Hashable
. The code is clean and concise, with only minor suggestions for improvement mainly around potential simplification and improved type safety.
