The minimum requirements for QuickBlox UIKit for iOS are:

  • iOS 15.0
  • Xcode 14

Before you begin

Register a new account following this link. Type in your email and password to sign in. You can also sign in with your Google or Github accounts.
Create the app clicking New app button.
Configure the app. Type in the information about your organization into corresponding fields and click Add button.
Go to Dashboard => YOUR_APP => Overview section and copy your Application ID, Authorization Key, Authorization Secret, and Account Key .

Install QuickBlox UIKit

To add QuickBlox UIKit to your project using SPM, you can follow these steps:

Open your Xcode project and navigate to File > Swift Packages > Add Package Dependency.
In the search bar, enter the QuickBlox UIKit repository URL: https://github.com/QuickBlox/ios-ui-kit.git and click Add Package.
Xcode will then fetch the SDK and you can add it to your project by clicking Add Package.
You can then import QuickBloxUIKit modules into your code and use its API.

import QuickBloxUIKit

Init QuickBlox SDK

To init QuickBlox SDK you need to pass Application ID, Authorization Key, Authorization Secret, and Account Key to the initWithApplicationId() method.

Quickblox.initWithApplicationId(92, authKey: "wJHdOcQSxXQGWx5", authSecret: "BTFsj7Rtt27DAmT", accountKey: "7yvNe17TnjNUqDoPwfqp")



It's not recommended to keep your authKey and authSecret inside an application in production mode, instead of this, the best approach will be to store them on your backend. Instead you can initialize QuickBlox SDK without Authorization Key and Secret


Before sending your first message you need to authenticate users in the QuickBlox system. You can read more about different ways of authentication by this link.
In our example we show how to authenticate user with login and password.

QBRequest.logIn(withUserLogin: "userLogin", password: "userPassword", successBlock: { (response, user) in
    // Navigate user to the UIKit
}, errorBlock: { (response) in

Show UIKit screen

struct ShowQuickBlox: View {
    var body: some View {


The QuickBlox UIKit for iOS allows you to create your own unique view of the UIKit.

Default themes

The QuickBlox UIKit for iOS by default supports Light and Dark themes, which theme will be applied depending on device settings.

Use your own theme

You can create and use your own theme. To do this you need to create class that implements QuickBloxUIKit.ThemeColorProtocol

class CustomThemeColor: QuickBloxUIKit.ThemeColorProtocol {
    var mainElements: Color = Color("MainElements")
    var secondaryElements: Color = Color("SecondaryElements")
    var tertiaryElements: Color = Color("TertiaryElements")
    var disabledElements: Color = Color("DisabledElements")
    var mainText: Color = Color("MainText")
    var secondaryText: Color = Color("SecondaryText")
    var caption: Color = Color("Caption")
    var mainBackground: Color = Color("MainBackground")
    var secondaryBackground: Color = Color("SecondaryBackground")
    var tertiaryBackground: Color = Color("TertiaryBackground")
    var incomingBackground: Color = Color("IncomingBackground")
    var outgoingBackground: Color = Color("OutgoingBackground")
    var dropdownBackground: Color = Color("DropdownBackground")
    var inputBackground: Color = Color("InputBackground")
    var divider: Color = Color("Divider")
    var error: Color = Color("Error")
    var success: Color = Color("Success")
    var highLight: Color = Color("HighLight")
    var system: Color = Color("System")
    init() {}

And use it later to create your own theme

var customTheme: CustomTheme = CustomTheme(color: CustomThemeColor(),
                                       font: QuickBloxUIKit.ThemeFont(),
                                           image: QuickBloxUIKit.ThemeImage())
QuickBloxUIKit.settings.theme = customTheme
