Fix some bugs in a SWIFT IoT iOS app

The app's architecture is VIPER and we deeply use RxSwift. So we are looking for a developer able to resolve the following issues: * Fetch data from API and populate an already designed list screen * Show at each API/long operation call a dialog with progress * Check for internet connection before starts API calls * Change order of screens at opening based on API call result * Add open app actions on two buttons (if the app exist otherwise let the user able to install through App Store) * Open a screen on the menu button * Change a parameter to use for the sending of a TCP message IMPORTANT: To check if the app is working correctly we have a simulator. For running successfully the simulator you will need a Linux OS or a MAC OS on your computer. You will have to be able to set-up and configure a WiFi Access Point on your computer. The simulator is a C program and needs to be compiled to run. The developer will be asked at the end to publish the updated app on the store.
