I removed my app from sale when Apple informed me it had to be updated. A few days ago I updated the app and submitted it for approval. It was approved shortly thereafter. On the App Store Connect page for the app, I clicked the Availability button for "All regions" and set the price to "Free". But 24 hours later, I'm still seeing "Removed from sale" displayed on that page. How can I get the app back on sale?

This is what I've been doing to change a single letter at a specific location in a word:let word = "abc" var letters = Array(word.characters) letters[1] = "x" let newWord = String(letters)Surely there's a more elegant way in Swift 3. But is this really it?let index = word.index(word.startIndex, offsetBy: 1) let range = index ..< word.index(after: index) word.replacingCharacters(in: range, with: "x")It works; but it looks hideous.
