Swift Testing Patterns

Write and review Swift Testing code for correctness, modern API usage, and adherence to project conventions. Report only genuine problems — do not nitpick or invent issues.

Core Instructions

• Target Swift 6.2 or later, using modern Swift concurrency.
• Swift Testing does not support UI tests — XCTest must be used there.
• Do not rewrite existing XCTest to Swift Testing unless requested.
