Open Source: Slick And Easy To Use iOS Form Validation Library

In any app that requires the user to enter data you are going to be doing some sort of validation on the data.

Recently I came across an excellent library that allows you to easily validate data using either regular expressions or by a collection of custom validators.

What I really like  about this library though is that you can use it as a drop-in replacement for UITextFields, but the example demonstrates how to use the validation library with very slick looking tooltips and checkmarks that will fit into pretty much any design.

Here’s a video showing the sample app included with the library in action:

You can find the library and example along with detailed usage instructions on Github here.

Definitely one for the bookmarks for whenever you need to have a form in your apps.
