I have no idea what a hot swap is and for the life of me cannot construct a google search that will find what it means in the context of my program. I was editing my class, the same way I do all the time, and when I went to run it I all of a sudden got a
Hot Swap failed: myClassName: schema not implemented
error.
Can anyone explain this to me in Layman's terms?

The HotSwap mechanism lets you reload classes changed during a debugging session without having to restart the entire application.
Go to the File –> Settings –> Debugger –> HotSwap and ensure that all checkboxes are checked and the radio button “Reload classes after compilation” is set to “Always”.
You are attempting to change your source code while the program (or IntelliJ's debugger) is still running. This is what the HotSwap feature does according to IntelliJ's KB.
Please make sure your program and/or debugger is stopped before re-launching the program and the issue should be resolved.
