Build an iOS app to read QR codes and record data
$750-1500 USD

How the app should work:
1) User opens app for the first time and is prompted to scan an event code [1]. This QR code will contain JSON similar to the following. This JSON data must be saved by the app in memory for later.
{
"name": "Some event",
"secret": "t4jQNrFnkEiI9IlNFue5HeexA4U6MXR0rCM4VOK7Sn8"
}
2) The user will be taken to the next screen with two buttons. One ("EXIT") deletes the previously saved event code, and takes them back to screen 1. The other opens another QR scanner, which will scan codes with the data similar to the following:
[login to view URL]
This string is a JSON web token (more information at [login to view URL]) which should be signed using the secret saved in step 1. Once decoded, the signature should be verified to ensure that the QR code is valid. The main body of the token will be similar to:
{
"reward": {
"name": "Backstage Access",
"icon": "vip-badge",
"restricted": false,
"expire": "dd-mm-yy hh:mm"
},
"user": {
"id": 123456,
"name": "Benedict Lewis",
"username": "benedictlewis"
}
}
The expire data should then be checked to ensure that the code has not expired. If the signature is not valid, or the code has expired then the "Invalid Reward" message box should be shown.
If [login to view URL] is true, the black "Age Verification Needed" box should be shown. If the user selects "ID Valid" then it should continue to the success modal.
If [login to view URL] is false, then it should go straight to the success modal. The success modal should be populated with the data from the token, including [login to view URL] and [login to view URL] (a set of icon files will be provided, and the names in the tokens will match the file names).
Below the name and icon the first initial should be shown, followed by a "." and their last name, and finally the user's username in brackets prepended with an "@" sign.
The details from the token should then be added to the list of issued rewards (in the format shown).
When the user clicks the big tick button it should go back to the QR screen to scan another code. If the user clicks the "X" it should go to the list of previously issued rewards. This list does not need to be saved anywhere, it is just for the users reference.
You'll be expected to implement this as per the design specification, following all the standard iOS design principles in terms of animations and transitions. This app is very simple, and requires no online activity or similar.
Please refer to the attached file (Glint iOS App.png) for design details and the users flow.
You will be expected to write this as a native iOS app using Objective C. Please do not submit any proposals which involve the use of Cordova or other similar packages.
