How to test if NewRelic’s recordError is working correctly in Swift

I had set up NewRelic in my iOS app for the first time but wasn’t sure if my recorded errors were coming through. So here’s the most basic way I found to test error handling. Credit — this is based on Edward Brey’s example on StackOverflow. Thanks, Edward!

struct SomeKindOfError: Error, LocalizedError {
  let errorDescription: String?
  init(_ description: String) {
    errorDescription = description
  }
}

do {
  throw SomeKindOfError("Description goes here")
} catch let error {
  NewRelic.recordError(error, attributes: [ "message": "This is my test error" ])
}

Thanks for reading! I hope this helps someone. If you’re having trouble finding the recordError output in the NewRelic interface, check out my guide on that.
