I have an existing Android app for scanning 2D barcodes and QR codes. It scans and interacts with an existing API to send scanned results to the server. A detail brief can be provided and the Android version can be made available for duplication. The Android version was built using the Materials design principal and uses native Android layout and UI concepts- I want the iOS version to leverage the native iOS equivalents to UX decisions.
A written description of the API usage is attached, this may seem confusing at first but when you get the Android version it makes a lot more sense.
