ConfigCat SDK for Swift


ConfigCat SDK for Swift provides easy integration for your application to ConfigCat.

ConfigCat is a feature flag and configuration management service that lets you separate releases from deployments. You can turn your features ON/OFF using ConfigCat Dashboard even after they are deployed. ConfigCat lets you target specific groups of users based on region, email or any other custom user attribute.

ConfigCat is a hosted feature flag service. Manage feature toggles across frontend, backend, mobile, desktop apps. Alternative to LaunchDarkly. Management app + feature flag SDKs.

Getting started

1. Install the package


Add the following to your Podfile:

target '<YOUR TARGET>' do
pod 'ConfigCat'

Then, run the following command to install your dependencies:

pod install


Add the following to your Cartfile:

github "configcat/swift-sdk"

Then, run the carthage update command and then follow the Carthage integration steps to link the framework with your project.

2. Go to Connect your application tab to get your API Key:


3. Import the ConfigCat module to your application

import ConfigCat

4. Create a ConfigCat client instance

let client = ConfigCatClient(apiKey: "#YOUR-API-KEY#")

5. Get your setting value

let isMyAwesomeFeatureEnabled = client.getValue(for: "isMyAwesomeFeatureEnabled", defaultValue: false)
if(isMyAwesomeFeatureEnabled) {
} else {

Or use the async APIs:

client.getValueAsync(for: "isMyAwesomeFeatureEnabled", defaultValue: false, completion: { isMyAwesomeFeatureEnabled in
        if(isMyAwesomeFeatureEnabled) {
        } else {

Getting user specific setting values with Targeting

Using this feature, you will be able to get different setting values for different users in your application by passing a User Object to the getValue() function.

Read more about Targeting here.

let user = User(identifier: "#USER-IDENTIFIER#")
let isMyAwesomeFeatureEnabled = client.getValue(for: "isMyAwesomeFeatureEnabled", user: user, defaultValue: false)
if(isMyAwesomeFeatureEnabled) {
} else {

Sample iOS app

Polling Modes

The ConfigCat SDK supports 3 different polling mechanisms to acquire the setting values from ConfigCat. After latest setting values are downloaded, they are stored in the internal cache then all requests are served from there. Read more about Polling Modes and how to use them at ConfigCat Docs.
