iOS Client

This library can be used with iOS and Mac applications. The source code for the client is available on Github.

Installation

CocoaPods

CocoaPods is a dependency manager for Cocoa projects. For usage and installation instructions, visit their website. To integrate Flagsmith into your Xcode project using CocoaPods, specify it in your Podfile:

pod 'BulletTrainClient', '~> 1.0'

Usage

Sign Up

Sign up at Flagsmith and create a project. Take a note of the API key which you will need to configure your app.

Initialization

Within your application delegate (usually AppDelegate.swift) add:

import BulletTrainClient

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {

BulletTrain.shared.apiKey = "<YOUR_API_KEY>"
// The rest of your launch method code
}

Now you are all set to retrieve feature flags from your project. For example to list and print all flags:

BulletTrain.shared.getFeatureFlags() { (result) in
    switch result {
    case .success(let flags):
        for flag in flags {
            let name = flag.feature.name
            let value = flag.value
            let enabled = flag.enabled
            print(name, "= enabled:", enabled, "value:", value ?? "nil")
        }
    case .failure(let error):
        print(error)
    }
}

To retrieve a feature flag boolean value by its name:

BulletTrain.shared.hasFeatureFlag(withID: "test_feature1", forIdentity: nil) { (result) in
    print(result)
}

To retrieve a config value by its name:

BulletTrain.shared.getFeatureValue(withID: "test_feature2", forIdentity: nil) { (result) in
    switch result {
    case .success(let value):
        print(value ?? "nil")
    case .failure(let error):
        print(error)
    }
}

These methods can also specify a particular identity to retrieve the values for a user registration. See Identities , using the forIdentity parameter.

To retrieve a trait for a particular identity (see Traits):

BulletTrain.shared.getTraits(forIdentity: "test_user@test.com") {(result) in
    switch result {
    case .success(let traits):
        for trait in traits {
            let name = trait.key
            let value = trait.value
            print(name, "=", value)
        }
    case .failure(let error):
        print(error)
    }
}
