It's a text file which I only need to read.

Thank you for your reply. Here's what my preview looks like. It's right above the expansion of the #Preview macro. I just added the return keyword right before HistoryView(words: $randomWords), but the problem persists. #Preview { let randomWord1 = FetchWord.getRandomWord() let randomWord2 = FetchWord.getRandomWord() @State var randomWords = [Word(word: randomWord1.0, IPA: randomWord1.1, lineNumber: randomWord1.2), Word(word: randomWord2.0, IPA: randomWord2.1, lineNumber: randomWord2.2)] return HistoryView(words: $randomWords) } What do you mean by "@State inline"? Does that mean I can't declare a ``@State` variable in my preview? Sorry, I am new to app development.

I figured it out by myself. Thank you for trying to help though!
