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.
- Make sure you have Xcode installed
- Open
hello-macos.xcworkspacein XCode - Set the value of
sdkKeyinAppDelegate.swiftto your LaunchDarkly mobile key. If there is an existing boolean feature flag in your LaunchDarkly project that you want to evaluate, setfeatureFlagKeyinViewController.swiftto the flag key.
// AppDelegate.swift
let sdkKey = ""
// ViewController.swift
let featureFlagKey = "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.
