@dennismm - Actually you can do it on the iPhone. Works on my iPhone 17 but I don't find it easy to use.
Enable Swipe to Type (QuickPath)
- Open the Settings app on your iPhone.
- Scroll down and tap General.
- Tap Keyboard.
- Find the "Slide to Type" option and toggle the switch to the On (green) position. (It's often on by default on newer iOS versions).
