Swift

Xcode project and workspace

You will be using the iOS Client SDK library inside an Xcode project you'll create next.

Create an Xcode Project

Open Xcode and, from the menu, select File > New > Project....
Select a Single View App for the Application type and click Next.
For the Product Name type in AppToAppChat, select the relevant Team and Organisation Identifier.
User Swift for Language and Storyboard for User Interface. Click Next.
Select the Desktop as the place where your project folder will reside. You can select a different location but please make sure to remember it as you'll need to navigate to it soon from the Terminal.
You now have a brand new Xcode Project.

Before continuing, please close the new project you created.

You will add the iOS Client SDK library to your project via CocoaPods.

Install CocoaPods

Open the Terminal app and navigate to the project folder by typing:

cd ~/Desktop/AppToAppChat

Install CocoaPods in your system, if you don't have it already:

sudo gem install cocoapods

Note: CocoaPods is built with Ruby, available by default on macOS.

Create a Podfile for your project:

pod init

Add the iOS Client SDK

Add the Vonage iOS Client SDK to the Podfile. To do this, let's open it in Xcode:

open -a Xcode Podfile

Update the Podfile as shown below:

# Uncomment the next line to define a global platform for your project
# platform :ios, '9.0'

target 'AppToAppChat' do
  # Comment the next line if you don't want to use dynamic frameworks
  use_frameworks!

  # Pods for AppToAppChat
  pod 'NexmoClient'
  
end

Install the library:

pod install

The latest version of the library will be added to your project:

Analyzing dependencies
Downloading dependencies
Installing NexmoClient (3.0.0)
Generating Pods project
Integrating client project

[!] Please close any current Xcode sessions and use `AppToAppChat.xcworkspace` for this project from now on.
Pod installation complete! There is 1 dependency from the Podfile and 1 total pod installed.

[!] Automatically assigning platform `iOS` with version `13.5` on target `AppToAppChat` because no platform was specified. Please specify a platform for this target in your Podfile. See `https://guides.cocoapods.org/syntax/podfile.html#platform`.

Open the Workspace

As described in the output above, please use AppToAppChat.xcworkspace rather than the initial project from now on. To open it, type the following in the terminal:

open AppToAppChat.xcworkspace
