Presenting Unanticipated Errors To Users

Check out the original article

This is the start of a really great series. It uses Swift for the examples but everything in the articles holds true for any language/platform

First, some quick terminology:

  1. an error condition is a failed conditional check that results in a function skipping its usual functionality and instead returning an nominated error value.

  2. an error is a value used to report that an error condition occurred and normal functionality was skipped

  3. error handling is code that looks for errors and performs different actions based on the presence of those errors

  4. error reporting communicates an error result from a user task to the user
