Getting started with iOS SDK

On this page

Step 1 - Setting up the iOS SDK
Step 2 - Installing the iOS SDK

This section describes how to set up and install the iOS SDK and how to deploy a feature flag.

Step 1 - Setting up the iOS SDK

To setup iOS SDK, follow these steps:

Create a CloudBees Feature Management account. See Signup Page to create an account.
Get your environment key.
- Get the key from App Settings > Environment > Key.

Step 2 - Installing the iOS SDK

For instructions on initializing the iOS package to your application., select your installation method:

CocoaPods
Carthage
Manual installation

CocoaPods

To install the iOS package, follow these steps:

In the podfile, add the following:
```
pod 'ROX'
```
To install the Cocoapods dependencies, run the following command in the terminal:
```
pod install
```

Carthage

To install the iOS package, follow these steps:

In the cartfile, add the following:
```
github "rollout/rox-ios"
```
To install the Carthage dependencies, run the following command in the terminal:
```
carthage update --platform iOS
```

Manual installation

To install the iOS package, follow these steps:

If you are already in the manual step screen on the dashboard, click download.
If for some reason you left the installation screen you can go back by clicking on Dashboard > Install Instructions.
Download the zip file and open it. Place the ROX directory under your application.
Add files to your project in Xcode by selecting ROXCore.framework and RoxSdk.xcodeproj.
Remove ROXCore.framework from Linked Frameworks and Libraries.
Click the plus sign (+) under Embedded Binaries and select both ROXCore.framework and ROX.framework.

Add the following lines of code to your application

Container class registration and environment key setup

You cannot call Rox.setup() twice in the same runtime.

Running the application

The flag name is automatically added to the CloudBees Feature Management dashboard after running the application.
