ReX-T

ReX-T allows you to easily develop complex Regular Expression patterns and test them. When your pattern is ready, the handy sample code generator will produce ready-to-use Swift or Objective-C source code that you can use directly in your application. Executing the pattern on any source text will give you a comprehensive overview of the matches, their positions and lengths. The built-in pattern history popup lets you reuse previous patterns. Developing Regular Expression patterns has never been easier!
