In this episode, Thomas Domville shows us how to use QuickPath, a native swipe keyboard new in iOS 13 that allows you to type by sliding your finger across the onscreen keyboard.
To use this feature, make sure you're using either Touch Typing or Direct Touch Typing as your typing mode, and rest your finger on a key. Then, after you hear a tone, slide it to the general location of your next intended key. For example, to type the word "Hello," rest your finger on the letter H, and when you hear the tone, slide it to the general location of the letter E, followed by the letters L and O. If the wrong word is predicted, press the Delete key, and it will be deleted.
To turn this feature off, go to Settings > General > Keyboard, and double-tap the "Slide to type" switch. Additionally, you can quickly turn this feature on and off by adding it to the VoiceOver rotor in Settings > Accessibility > VoiceOver > Rotor > Rotor items.
