### iOS (App Store)

To publish your app to the App Store, you must first open it in Xcode (the .xcworkspace folder). After making any necessary changes, you can distribute it to App Store Connect by clicking Archive. <mark style="color:red;">**You must open the .xcworkspace file of the iOS project.**</mark>
