Add some small features to my existing app

Take my current app and add features to it. • Code must be written in Objective C • Code must be clear with comments in English • No hard coded strings: Separate for localizing • Final delivered asset is an Xcode project file with the entire app functioning with no warnings or errors. All code CANNOT be reused for another project and 100% ownership is transferred to me once the payment has been made. I will send a pdf with all details of the app.
