Update iOS App

Hi, We need to update an iOS app [currently functioning] by adding this functionalities; general preview of what the app does: the employer sends work assignments to his employees and they receive those requests in the app [it's for employees use] so they can accept or reject them. There are two types of requests, one needs to check the start and end time manually, and other one that hands a code. 1. Add an option to input a quantity [right now it can take a picture of a receipt, now we need to add the quantity]. There are 2 kinds of receipts needed [one is new]. 2. Add an option to leave a signature and a name [and save them locally until they are send to the server] 3. There are different parts of the app that shows a date [saved on the database], but in different formats [e.g. November 09, 2017; 11/09/2017; etc]. We need them to have the same format MM/DD/YYYY 4. In one view, make small changes in the position of some buttons [like adding some margin to them] We would work on the needed APIs, the project is on GitHub Regards
