iOS Quick Start

This is a walkthrough on how to get a single Portal + web application setup. To begin this walkthrough it will be assumed that you have already signed up for access to Portals and you have your Portals key ready.

First have your web application ready. We will add some configuration to it and then get it setup in Appflow. At the end of this walkthrough:

  • the web application will be setup in Appflow
  • each new Xcode iOS application build will pull the latest version of the web application from Appflow
  • the iOS application will have a Portal setup pointing to the web application files.

1. Create a capacitor config​

Create a capacitor.config.json file to the root of your web project. We will not need to add Capacitor to the web project but this configuration file will help us configure some options for the Portals that are displaying this web application.

{
  "appId": "com.ionicframework.featured-products",
  "appName": "Featured Products",
  "webDir": "build"
}

These configuration values are required for web applications added to Appflow.

  • appId, a unique id that you provide to your web application
  • appName
  • webDir, the directory where your compiled web code will be placed
note

There are many options that you can provide to a Capacitor configuration file we will only need a few to get started. These options are defined in the config schema.

2. Add the web application to Appflow​

Now that we have the application source configured we will need to add it to Appflow. Appflow can be used for deploying the web application into the Portal later using Live Updates.

During the Native App build process the most recent build of the web application will be used to seed the Portal, and then after the Native App deployment every subsequent build can be deployed as an over the air Live update.

Connect the repo​

After logging into your Appflow account go to the Apps page.

In the upper right hand corner you will be able to select Import existing app.

  • Provide an App Name. Most likely using the same you provided in the capacitor.config.json file in the previous step.
  • Capacitor, as the mobile architecture
  • Choose your git host. In this example we have selected Github

Web application builds​

After the app has been created you will want to go to the Builds page. This is where you will create new builds and see previous builds. Anytime you want to deploy a new version of the web application you will need to create a build from this screen or by using the Ionic Cloud CLI (which we will cover later).

tip

Also in the top left corner of these screens you will see the Appflow App id. In this case it is 11a0971f. This id will be used when we configure the native application.

Build the connected application​

After the application has been added to Appflow you will need to create your first build so that it is available to seed the Portal in the Native App.

This can be done by hitting the New Build button on the 'Builds' page. Then you will choose a the most recent commit to create the build from.

When creating a new build there are a few values that we need to change on the initial build for the app.

  • Target Platform should be Web
  • Build Stack should just be the default which is the latest.
  • Live update should be turned on and Channel should be set to production

3. Setup local dev environment​

Create a Personal Access Token​

Now that we have the web application all setup in Appflow and built we need to get our local environment setup to be able to pull it from Appflow.

The first step in setting up our local environment is generating a personal access token.

This is done from Personal Settings in the Personal Access Token tab.

Click the Generate new token button. While creating the token it is a best practice to give it an optional expiration date but not required.

tip

After the token is generated you will need to copy it to clipboard because it will be required for the next step. Usually the token follows the format of ion_XXXXXXXXXXXXX.

Create a cloud configuration file​

Now create a yaml configuration file in your native project. This file will be used to authenticate against Appflow for your cloud interactions. Usually you will place this file in your native applications source root. It will be referenced by a build script in your native application.

TOKEN: ion_XXXXXXXXXXXXX
note

Be sure to set this to ignore in your .gitignore Learn more about the configuration file.

Install the Ionic Cloud CLI​

Install the Ionic Cloud CLI within your local dev environment. This CLI will allow us to interact with Appflow programmatically. So that we can pull the latest Build files during native builds. (https://ionic.io/docs/appflow/cli/overview)

(export IONIC_CLOUD_VERSION=0.7.0; curl -sL https://ionic.io/get-ionic-cloud-cli | bash)

Create web application download script​

The last step in setting up the local environment is adding a script to the project in XCode so that it will download the latest web application build from Appflow every time the iOS application is built.

Open Xcode and go to your Project settings. Add a new build phase of type New Run Script Phase.

The following bash code should be added to the build process.

APP_ID=11a0971f
CHANNEL=production
PORTAL_NAME=featured_products

ionic-cloud live-update download \
  --config="${SOURCE_ROOT}/.ionic-cloud.yaml" \
  --app-id ${APP_ID} \
  --channel-name ${CHANNEL} \
  --zip-name ${PORTAL_NAME}.zip


unzip ${PORTAL_NAME}.zip -d \
  ${BUILT_PRODUCTS_DIR}/${TARGET_NAME}.app/${PORTAL_NAME}
rm ${PORTAL_NAME}.zip

There are a few variables that you will need to setup at the beginning of script.

  • APP_ID - Web application id from Appflow
  • CHANNEL - Live update distribution channel.
  • PORTAL_NAME - Choose a name for the portal, no spaces.

4. Setup Portals in your iOS App​

Install the Cocoapod file​

note

IonicPortals requires using Cocoapods 1.10 or greater.

To add Portals to your iOS project, put the following line to your Podfile:

Podfile
pod 'IonicPortals', '~> 0.11.0'

And then run pod install.

Add the Portals key​

After installation of Portals we can setup the Portals key. Then the application is ready to have its first Portal configured. A typical place to do so is in the AppDelegate application(_:didFinishLaunchingWithOptions) method. There, you can use the PortalsRegistrationManager to register:

import UIKit
import IonicPortals

@main
class AppDelegate: UIResponder, UIApplicationDelegate {
  func application(_ application: UIApplication, didFinishLaunchingWithOptions
  launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
    // Override point for customization after application launch.
    PortalsRegistrationManager.shared.register(key: "YOUR_PORTALS_KEY")
    return true
  }
}

extension Portal {
  static let featuredProducts = Portal(
    name: "featured_products",
  )
}

Create the first Portal​

Now that the application has been configured all we need to do is add the Portal to a view. By default, a Portal will use the name property as the directory to load web content from (relative to the root of Bundle.main). You can also specify another directory for the content.

class ViewController: UIViewController {
  override func loadView() {
    self.view = PortalUIView(portal: .featuredProducts)
  }
}
caution

Avoid committing your Portals key to source code repositories where it may be publicly visible! On iOS, you can use an .xcconfig file to keep it out of a public repository.

Finished with setup​

Thats it! Portals is now setup in your application and you can add new Portals at any time. Now it is time to build the iOS app in Xcode and see it working in the emulator or on device. Now any time a new deployment is done to the production channel subsequent Xcode builds will pull in the latest version.

Next step would be to setup Live Updates within your application.
