Entering a URL when using SwiftKey is easy, all you have to do is make sure you're typing in lowercase and then type 'www'.
For example, if you wanted to type a URL at the beginning of a sentence, just tap on the ‘shift’ key (the arrow key on the bottom left of the keyboard) twice to bring it to lowercase. From there, you can easily enter URLs that start with ‘www.’
If you’re typing a URL mid-sentence, starting with ‘www’ will automatically put SwiftKey Keyboard into URL mode.
Quick note to remember: this feature only works when starting a URL with ‘www.’
