Installation

Minimum supported iOS version is 11.0, supported language is Swift.
The iOS User.com SDK should be installed or updated using CocoaPods, a dependency manager Swift projects. CocoaPods provides added simplicity for integration and updating.

Step 1. Install CocoaPods
Before beginning this process please ensure that you are using Ruby version 2.0.0 or greater.
To get started simply run the following command in your terminal:
```
$ sudo gem install cocoapods
```
More information about installation process can be found in Getting Started Directions on CocoaPods.org. If you have any issues regarding CocoaPods additional help can be found in CocoaPods Troubleshooting Guide.
Step 2: Constructing the Podfile
Now that you’ve installed the CocoaPods Ruby Gem, you’re going to need to create a file in your Xcode project directory named Podfile. The contents of the file should look like this:
```
platform :ios, '11.0'
use_frameworks!

target 'YourApp' do
  pod 'UserSDK', :git => 'https://github.com/UserEngage/iOS-SDK'
end
```
Please remember to replace YourApp with a name of your target in the contents of Podfile.
Step 3: Installing the SDK
To install the User.com SDK, navigate to the directory of your Xcode app project within your terminal and run the following command:
```
pod install
```
At this point you should be able to open the new Xcode project workspace created by CocoaPods. Remember to open Xcode project workspace instead of Xcode project!
Step 4. Initialize SDK in your app
To initialize User.com SDK, you need to add the following line of code to the top of your AppDelegate.swift file:
```
import UserSDK
```
Then initialize User.com builder with your SDK API key, context and base URL. It will initialize User.com instance.
You can generate API key in User.com web panel, as described in getting started section.
Within your AppDelegate.swift file, add the following snippet within your
```
application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool 
```
method:
```
let sdk = UserSDK(
application: UIApplication.shared,
apiKey: "<api_key>",
baseURL: "<your_domain>.user.com",
shouldTrackActivities: true)
```
Be sure to update api_key and your_domain with the correct values from your App Settings page. If you want to track you client’s mobile view screens activities remember to set shouldTrackActivities to true.
