macOS Swift app to check an Amazon SQS queue

Need a very simple application, just a proof of concept application that will run on the macOS, check an Amazon SQS queue for message, and if one exists, launch a script. This app should: 1. Run and show its icon on the menu bar as a background application 2. Have a preferences panel to input configuration (detailed below) 3. Check the queue every X minutes 4. If a message is detected, launch a bash script (this can be a simple Hello World demo) the preferences panel should have entry blanks for the following: Amazon credentials the SQS arn to check Entry blank to set how many X minutes to check the queue The path to the bash script to run That's pretty much it. We're not doing anything with the contents of the message, and the bash script is demo. Preferable to use latest Swift, we'll be using latest Xcode to compile here.
