Overview

Real time Swift iOS Chat with Firebase - Messenger Clone

This is an extremely simple chat app source code of an iOS Swift Chat app. It leverages MessageKit and it stores and retrieves data to/from Firebase Firestore. The app design is inspired by Facebook Messenger. Clone the iOS Chat App Source Code and add a fully fledged chat to your app in minutes.

Learn how to build your own iOS chat feature with only a few lines of code. Clone this iOS chat app source code and get started by following the steps below. For more details, check out our detailed technical documentation on the official iOS Swift Chat app page.

If you get a build error in latest Xcode, make sure you run Xcode's Legacy Build System (File -> Workspace Settings).

How to run a demo app

Download the source code by cloning this repository
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.
Install the pods by running

pod update

Open the xcworkspace file with the latest version of Xcode

How to integrate the chat into your app

Download the source code and import the "Core" folder into your Xcode project
Make sure you add all the Podfile dependencies into your own Podfile
Replace the GoogleService-Info.plist file with your own file, downloaded from Firebase Console.
Install the pods

pod update

Use the following code to instantiate a chat view controller

let uiConfig = ATCChatUIConfiguration(primaryColor: UIColor(hexString: "#0084ff"),
                                      secondaryColor: UIColor(hexString: "#f0f0f0"),
                                      inputTextViewBgColor: UIColor(hexString: "#f4f4f6"),
                                      inputTextViewTextColor: .black,
                                      inputPlaceholderTextColor: UIColor(hexString: "#979797"))
let channel = ATCChatChannel(id: "channel_id", name: "Chat Title")
let viewer = ATCUser(firstName: "Florian", lastName: "Marcu")
let chatVC = ATCChatThreadViewController(user: viewer, channel: channel, uiConfig: uiConfig)

// Present the chatVC view controller

Customize the UI by updating the ChatUIConfiguration class

    let mainThemeBackgroundColor: UIColor = .white
    let mainThemeForegroundColor: UIColor = UIColor(hexString: "#3068CC")
    let mainTextColor: UIColor = UIColor(hexString: "#000000")
    let mainSubtextColor: UIColor = UIColor(hexString: "#7e7e7e")
    let statusBarStyle: UIStatusBarStyle = .default
    let hairlineColor: UIColor = UIColor(hexString: "#d6d6d6")

    let regularSmallFont = UIFont.systemFont(ofSize: 14)
    let regularMediumFont = UIFont.systemFont(ofSize: 17)
    let regularLargeFont = UIFont.systemFont(ofSize: 23)
    let mediumBoldFont = UIFont.boldSystemFont(ofSize: 17)
    let boldLargeFont = UIFont.boldSystemFont(ofSize: 23)
    let boldSmallFont = UIFont.boldSystemFont(ofSize: 14)
    let boldSuperSmallFont = UIFont.boldSystemFont(ofSize: 11)
    let boldSuperLargeFont = UIFont.boldSystemFont(ofSize: 29)

    let italicMediumFont = UIFont.italicSystemFont(ofSize: 17)

I am unable to get the receiver message

I have downloaded code and update the pod. Integrated GoogleInfo.plist in the source code. When I run the code, I am able to send the message and message is storing on firebase database, while unable to get message of receiver if receiver reply for my message. Please suggest what am I missing. I am using two different simulator with different sender and receiverID.

Updated for latest Xcode/Swift syntax
Updated project to resolve semantics issues with Xcode 10 and latest version of Swift

Removed Google .plist, users will have to provide their own

There is one outstanding issue of having to remove the camera button. The .system reference in the base master is no longer possible, would be good to know what the right approach for that is and have it re-implemented.

Firestore convenience, camera button added back, pods removed, .gitignore implemented, other stuff

added a convenience class that will help new devs get this working with a new instance of Firestore (ATCRemoteData.swift), added .gitignore to prevent accidental commits with GoogleService-Info.plist, gitignore won't track or add pods or Podfile.lock, debugging statements added throughout-- not having them means a clean terminal, but it is damn hard to stack trace if we don't know what is working and how. Also, modified ID scheming, it is more logical to make the chat threads look like {userID}:{userID} instead of concatenating the two

I want to display text messages in different ways (e.g.. all CAPS), but what variable is the text stored??

I want to allow the user to display incoming messages in different ways (for example, a user might want to show all incoming chat messages in all CAPS). But I'm confused... in what variable is the text stored?

I'm looking in the ATCChatMessage.swift file, and I see three variables which seem to store the message's text: (1) content: String, (2) messageText: String, and (3) kind: MessageKind (which I realize is a MessageKit Type). I don't really see a difference between "content" and "messageText". I guess, to simplify my question, where in the swift code is the chat message text displayed, and from what variable is it fetching from? That way I know which variable I can edit if I want the user to make different adjustments on the text based on predefined settings.

Any help from someone would be greatly appreciated!

Can not send Photos

When using the ChapAppTemplateSwiftMarch 15 demo app, I can not get photos to show in the Chat room.

When using the camera, I get the console message as follows: [Camera] Failed to read exposureBiasesByMode dictionary.

When using the photo library, I do get: [LayoutConstraints] Unable to simultaneously satisfy constraints. Probably at least one of the constraints in the following list is one you don't want. Try this: (1) look at each constraint and try to figure out which you don't expect; (2) find the code that added the unwanted constraint or constraints and fix it. ( "<NSLayoutConstraint:0x2800bbde0 UIView:0x1055e17e0.width == - 16 (active)>" )

Will attempt to recover by breaking constraint <NSLayoutConstraint:0x2800bbde0 UIView:0x1055e17e0.width == - 16 (active)>

Make a symbolic breakpoint at UIViewAlertForUnsatisfiableConstraints to catch this in the debugger. The methods in the UIConstraintBasedLayoutDebugging category on UIView listed in <UIKitCore/UIView.h> may also be helpful. 2020-11-08 13:38:52.843059-0800 ChatApp[2194:311708] [View] First responder warning: '<ChatApp.InputTextView: 0x109023800; baseClass = UITextView; frame = (0 0; 297 30); text = ''; clipsToBounds = YES; tintColor = UIExtendedSRGBColorSpace 0.188235 0.407843 0.8 1; gestureRecognizers = <NSArray: 0x282c791a0>; layer = <CALayer: 0x28226f940>; contentOffset: {0, 0}; contentSize: {150, 31.333333333333332}; adjustedContentInset: {0, 0, 0, 0}>' rejected resignFirstResponder when being removed from hierarchy

Does anyone got a newer version already?

Keep the work up! really cool project, and I am really very very sad that I can't actually add it to my social media app :(

'MessageInputBarDelegate' has been explicitly marked unavailable here
When I build on Xcode I receive:

'MessageInputBarDelegate' has been renamed to 'InputBarAccessoryViewDelegate'

Upon some research in MessageKit I've found:

https://github.com/MessageKit/MessageKit/blob/5e16637ffc1fb39f2c3f9bc3396bbee41118947d/Sources/Supporting/MessageInputBar.swift#L31

https://github.com/MessageKit/MessageKit/blob/413fd8f6ebad43efdde5f98be5fafb2e7986d83b/CHANGELOG.md#dependency-changes

So I suppose MessageKit should be pegged to a version in the Podfile, but I'm unsure what version it was intended for...
