Swift Code Logical Error Audit

I have an existing iOS project written in Swift that compiles and launches, yet certain features do not behave as intended. What I need is a careful sweep of the code-base focused strictly on logical errors—places where functions return the wrong value, state changes happen in the wrong order, or edge-cases slip through conditional logic.

You’ll have access to the full Xcode workspace plus any supporting assets. Once inside, trace the execution paths, run the usual unit-testing suite (or create a lightweight one if it’s missing), and flag every spot where the logic breaks down. Please correct each issue directly in the code and annotate your changes so I can follow along later.

Deliverables:
• Updated Swift project that builds cleanly and behaves as expected
• A brief changelog summarising each logical error found, why it occurred, and how you fixed it

No UI redesigns or performance tuning are required at this stage—just solid, accurate logic so the app can run reliably.
