##Summary Info

This library is founded on the basis that commonly performed tasks, which take several lines of code to write should be encompased into simple methods, either using class extensions or services, that can be written in a single line of code. Thus reducing code redundancy and increasing code readibility.

In this package you will find the following:

  • A collection of NSDate Helpers
  • Button and View helpers to make good looking views easily and handle things like rounding, borders and more
  • An Array and Dictionary extension to convert to and from JSON
  • AN HTTP Request class to easily send api requests without any non-standard libraries
  • A UIImage View extension to load images from a URL and cache the image locally.
  • A Validation Helper class for NSString
  • String and NSData cryptography Helpers
  • NSThread Helpers to easily run blocks on the main and background threads
  • A Speech Service for speech to text.
  • UIAlertController Helpers to show with actions and text input
  • Image Helpers for things like blurring and resizing
  • Animation and Motion Effects Helpers
  • A View Controller helper that can recursively determine the visible view controller from anywhere in your application
  • A new helper that shows text on screen for a short time, like an Android "Toast"
  • Network Reachability Helper
  • An Event Counter to track the number of times an event has occurred during the life of an app, or daily.
  • Blurred Background Helpers, to present a view over another and blur the background.
  • Keyboard Helpers to add an action tool bar and hide the keyboard on click
  • TextField subclasses for date and value inputs
  • A service to help send emails easily from anywhere

Enjoy! Please feel free to fork and contribute to this repo!


ios 7+


SeaseAssist is available through CocoaPods. To install it, simply add the following line to your Podfile:

pod "SeaseAssist"

And import the following Header file

#import "SeaseAssist.h"

This pod will work if your project uses objective-c or Swift.

  • For best results with an objective-c Project, add the SeaseAssist.h import into your .pch file and you will not need to import SeaseAssist into each of your classes that references it.
  • For Similiar result with Swift, you should NOT include the use_frameworks! in your pod file and add a bridging header that includes the library. If you must use_frameworks!, then you need to include SeaseAssist in any class that uses its functions. -- add a new header file to yoour project named ProjectName-Bridging-Header.h -- add '#import <SeaseAssist/SeaseAssist.h>' to your header file -- in your Target Build settings -> Swift Compiler Code Generation -> Objective-C Bridging Header, add a reference to the newly created file. Should be [ProjectName/ProjectName-Bridging-Header.h]
