iOS Swift App for kids

We’re looking for an iOS app written in Swift, targeted to iOS 13. The app is geared toward small children, so the idea is to keep it very simple. All images will be changed later for the final ones. We’ll need the source code for the app for future changes and enhancements. Main Screen: The main screen is a circle with 4 slices (as in [login to view URL]). Those 4 slices are pictures, and the wheel is static. When clicked, each of the 4 slices opens another view: - Chemistry eBook - Physics eBook - Periodic Table - Video There’s also a “more” button on the top right of the page that opens a settings/help pane. eBook Pages: Two eBooks will be presented from PDF, a simple PDFKit viewer that opens the pdf should suffice. There should be a “home” button that returns to the Main Screen. Periodic Table: The periodic table view is a simple periodic table that will look like the provided picture ([login to view URL]), where information for each element is initially provided by a JSON file provided by the [login to view URL] project. The JSON file provides xPos and yPos Coordinates to place the elements on the grid. Each element will have a colour assigned by a key-value or CSV file (whichever you prefer) with the Atomic Number as key, and the standard HEX representation of the RGB colour as value (0x000000 for Black, 0xFFFFFF for white). All the labels and boxes of the element should be drawn using the correct color for the element. There should be a “home” button that returns to the Main Screen. When an element is clicked, an “element card” page will be displayed, which looks like the provided element picture ([login to view URL]). The correct colour should also be used for all the features of the element card. There should be a “back” button that returns to the Periodic Table. Video Page: This page will play a video from a predefined URL in a simple embedded player. The video will be in standard MPEG-4 h.264 encoding. Basic video controls (Play/Pause, Forward and Rewind) are all that’s needed, and there should be a “home” button that returns to the Main Screen.
