IOS APP Code Review and Bug Fixing Work 1or 2 Days Work

I am seeking talented and experienced iOS developers to assist with reviewing and bug-fixing of an existing app written in Swift. I have existing source code available, and the estimated duration of the project is 1-2 days. The developer must have extensive experience working with Swift, as well as experience bug fixing and reviewing source code. The goal is to make sure that the code is doing what it should and that the app is running to its maximum efficiency. If you can provide the expertise I am looking for, please submit a proposal. Looking forward to our collaboration together!
