We've built a simple mobile application that demonstrates how LaunchDarkly's SDK works.

Below, you'll find the build procedure. For more comprehensive instructions, you can visit your Quickstart page or the iOS reference guide.

1. Make sure you have Xcode installed
2. Make sure you're in this directory and then type pod install
3. Open hello-ios.xcworkspace in Xcode
4. Set the value of sdkKey in hello-common/LDClientConfigurator.m to your LaunchDarkly mobile key. If there is an existing boolean feature flag in your LaunchDarkly project that you want to evaluate, set featureFlagKey in hello-ios/ViewController.m and hello-watchOS Extension/InterfaceController.m to the flag key.

    // hello-common/LDClientConfigurator.m
    NSString * const sdkKey = @"";

    // hello-ios/ViewController.m
    self.featureFlagKey = @"sample-feature";

    // hello-watchOS Extension/InterfaceController.m
    NSString * const FEATURE_FLAG_KEY = @"sample-feature";

You should see the message "The feature flag evaluates to .". The application will run continuously and react to the flag changes in LaunchDarkly.
