Customize iOS App & Sync with Codeigniter Script

Hi Freelancers, There are 2 main phases to this project. 1) Customize the UI based on an existing live app The app we are modelling the UI against is: [login to view URL] The main parts we are modelling are: - The 5 tab bottom navigation area - (See attached Screen 1) - (See attached Screen 2) - (See attached Screen 3) - (See attached Screen 4) 2) Syncing of data to and from a Codeigniter PHP Script (2 way syncing, not just 1 way) I need you to customize an existing iOS mobile app to sync data to and from a Codeigniter PHP script, which is a school management script as well - you can see some screenshots from the full desktop web app. The iOS mobile app template (built on Xcode7 & Swift2) is purchased here: [login to view URL] This iOS app is made to be syncing from the full web app template here: [login to view URL] However, we are not syncing to iOS app to its accompanying Codeigniter script. Instead, I have my own Codeigniter script and need this iOS app base to work with the Codeigniter script that I have. Existing modules we that are already in the purchased iOS app template that needs to be synced to the Codeigniter script (do also have a look at the screenshots on the iOS template sales page): - List of Students & Teachers - Manage profile of student & teachers - List down income (payments received) - Lesson Schedule (which is named as "Class Routine") - Student Attendance All these modules will be inside the full Codeigniter script so the main work is the 2-way syncing of data. Thanks for reading and please only bid if you are familiar with BOTH Codeigniter & of course iOS. Preferable if you can develop on Android too, we will be working on Android after this project is completed.
