I use double tap on the back to activate “Reachability” (screen slides down) on my iPhone, works somewhat okay

Yes, I have been using swipe typing since the Nokia N9, which had this feature. However, there was a gap in my use when the iPhone didn’t support custom keyboards. It wasn’t until they introduced the capability and implemented it natively that I started using swipe typing again.

It shouldn’t show the URL, have you added wefwef to the Home Screen?
