I was playing with WordScamble and had the root word "swigging". The first word I attempted to enter was "swigg". This was a deliberate typo using letters that were in the root word. This could be a typo for "swig" or perhaps "swing". The app simply assumed "swig" and added that to the word list. I then discovered that autocorrect is enabled for TextField by default. Since it corrected without any warning or asking the user, perhaps autocorrect should be disabled for this project?

@Nigel has the correct answer.

But maybe you don't know about @twostraws' amazing collection of SwiftUI hints and articles?

In the upper right corner of each web page, there's a sweet searchbox. Give it a go!

Here's the resulting article:

Thanks.
