Running the app

  1. Download the source code by cloning this repository
  2. Download the GoogleService-Info.plist file from your Firebase Console and replace the existing file in ChatApp folder. This will connect the app to your own Firebase instance.
  3. If you don’t have Cocoapods already, install it by following their instructions
  4. Install the pods by running
    pod update
  5. Open the xcworkspace file with the latest version of Xcode

Download our free chat app template and make it your own, by skinning the user interface as you want. Follow our detailed Messenger Clone app tutorial on how to make further customizations.

Most iOS apps need a social chat feature built in their user interface. If you're building a social network or functionality that requires chatting (such as customer service, for instance), skip the overhead of implementing everything from scratch and just reuse our free Swift chat implementation. By using Google’s Firebase Cloud Firestore to store and retrieve all the messages, you’re also saving a lot of work that needs to be done on your own servers. An insane amount of work! Plus, it comes with bulletproof security, provided by Google itself. Huge shout out to MessageKit contributors, who made this easier for us!

What Our Clients Are Saying

Speed & Costs

Instamobile's codebase proved to be incredible. We built our solution in just a matter of days. This was a project estimated to 15 months by several development teams we discussed with. It's insane how much money and time it saved us!

David Adams


I'm really impressed by how well organized the code is. It's relatively easy to add new components and stuff. I'm a newcomer with React Native and it was easy to understand the code. The integration with Firebase is amazing, the app works really fast.

Alex Chu


Overall, it's remarkable. The code is amazingly clean and well-written -- super elegant. I learned about a lot of performance optimizations that I was not familiar with, such as video compression, memoization, and disk caching. The app is crazy fast!
