Appending text to NSTextView in Swift 3
I am building an application that utilizes an MDM API to make bulk updates to attributes of devices. I am looking to have some sort of visible output/logging in the main view so that the user can see what lines of their CSV may have failed and what the HTTP Response Code was. I can append to an NSTextField or a label easy enough, but seeing as how there may be a large output with many lines, I'd like to have a scrollable text box to append the information to. All of the documentation that I've found for doing this seems to be Swift 2, and this is the one piece of the puzzle I'm missing.
