Article: You can find the App Store icon on one of your Home screens. Third-party keyboards like SwiftKey and Gboard need to be installed from the App Store before they can be selected. You'll see this at the bottom of the screen.   Note that not all available keyboards will be displayed here. If you're looking for a specific keyboard and aren't finding it, tap the Search tab and search for it.   Return to the Home screen and tap the Settings app to open your Settings menu.        This will allow the keyboard to access your typing history, which it will need to use predictive text. Make sure you trust the developer before enabling this option. Generally you should stick to keyboards from known and trusted companies like SwiftKey and Google. You won't need to enable this if you just want basic functionality from the keyboard.
