An assistant to manage the interactions between view and model

Swift 5 license MIT CocoaPods Compatible Platform codebeat badge Carthage compatible Twitter

ModelAssistant is a mediator between the view and model. This framework is tailored to work in conjunction with views that present collections of objects. These views typically expect their data source to present results as a list of sections made up of rows. ModelAssistant can efficiently analyze model objects and categorize them in sections. In addition it updates adopted view to its delegate, based on model objects changes.


  • Inserting / Removing / Ordering / Updating model objects
  • Notifies changes to view
  • Full compatible with UITableView and UICollectionView
  • Supports Sections
  • Supports index titles
  • Compatible with Server data source
  • Compatible with all kind of persistent stores
  • Compatible with all design patterns
  • Easy to use
  • Thread safe
  • Fault Ability
  • Complete Documentation

What's New:

Version 1.1.3:

Now using modelAssitant is really easy with just two lines of codes, and delegates will be implement automatically to your collection view.

See Usage for new way of implementing modelAssistant.


Upgraded to Swift 5

Version 1.0.8:

  • Fault Ability: Now you can make entities in an specific range fault or fire them. For more information see Advanced Usage


  • iOS 8.0+
  • Xcode 8.3+
  • Swift 3.1+



CocoaPods is a dependency manager for Cocoa projects. You can install it with the following command:

$ gem install cocoapods

To integrate ModelAssistant into your Xcode project using CocoaPods, specify it in your Podfile:

source ''
platform :ios, '10.0'

target '<Your Target Name>' do

    pod 'ModelAssistant'

If you are not upgraded to Swift 4.2, use the last non-swift 4.2 compatible release:

If you are using swift 4, replace pod 'ModelAssistant' with this:

pod 'ModelAssistant', '1.0.1' #Swift 4

If you are using swift 3, replace pod 'ModelAssistant' with this:

pod 'ModelAssistant', '1.0.0' #Swift 3


Carthage is a decentralized dependency manager that builds your dependencies and provides you with binary frameworks.

You can install Carthage with Homebrew using the following command:

$ brew update
$ brew install carthage

To integrate ModelAssistant into your Xcode project using Carthage, specify it in your Cartfile:

github "ssamadgh/ModelAssistant"

Run carthage update --platform iOS to build the framework and drag the built ModelAssistant.framework into your Xcode project.


If you prefer not to use any of the aforementioned dependency managers, you can integrate ModelAssistant into your project manually.

Embedded Framework

  • Open up Terminal, cd into your top-level project directory, and run the following command "if" your project is not initialized as a git repository:

    $ git init
  • Add ModelAssistant as a git submodule by running the following command:

    $ git submodule add
  • Open the new ModelAssistant folder, and drag the ModelAssistant.xcodeproj into the Project Navigator of your application's Xcode project.

    It should appear nested underneath your application's blue project icon. Whether it is above or below all the other Xcode groups does not matter.

  • Select the ModelAssistant.xcodeproj in the Project Navigator and verify the deployment target matches that of your application target.

  • Next, select your application project in the Project Navigator (blue project icon) to navigate to the target configuration window and select the application target under the "Targets" heading in the sidebar.

  • In the tab bar at the top of that window, open the "General" panel.

  • Click on the + button under the "Embedded Binaries" section.

  • You will see two different ModelAssistant.xcodeproj folders each with a ModelAssistant.framework nested inside a Products folder.

    It does not matter which Products folder you choose from.

  • Select the ModelAssistant.framework.

  • And that's it!

    The ModelAssistant.framework is automagically added as a target dependency, linked framework and embedded framework in a copy files build phase which is all you need to build on the simulator and a device.


What is the position of ModelAssistant in design patterns?

ModelAssistant is fully compatible with all kind of design patterns. It doesn't violate them, instead it finds its place and sit there! As a guide the position of ModelAssistant in some of famous design patterns is as follows:

Design Pattern ModelAssistant Position
MVC Controller
MVP Presenter
MVVM ViewModel
VIPER Presenter
