iOS Input Validation

Here's an input validation pattern for iOS.

No validation patterns existed in Apple's guidelines so we had to invent a new one. It uses 'checkmark' validation alongside the input showing validity using an icon and colour. When the user tries to proceed an alert is flagged up if it isn't valid and they return to the screen.

The design did not accommodate hint text because the platform could not facilitate serving it up - a back-end issue!
