iOS Configuration

[中文版本]

Creating your iOS RainMaker Project

All the configuration related fields are kept in the property list file Configuration.plist. It can be found in the root directory of the project. Open it in Xcode and add value for properties described below.

AWS Configuration

RainMaker uses Amazon Cognito to provide authentication, authorization and user management in mobile apps. It also uses Amazon Web Services to provide RESTful APIs for communicating with devices. These settings need to be configured in the app and are clubbed into AWS Configuration key in Configuration.plist.

Key	Type	Description
App Client ID	String, Required	Uniquely identifies an app in a user pool. To get this value:

• Login to ESP dashboard with superadmin credentials.
• Go to Deployment settings, then from left navigation pane select "deployment details".
• Find app client Id in Cognito details section. | | Authentication URL | String, Required | OAuth URL for third party login. Check Getting The Authentication URL | | Base URL | String, Required | Consistent part of each API endpoint. Follow Get Base Url steps to fetch the endpoint. | | Redirect URL | String | Add the following value here: <Bundle ID>://success. For steps to create Bundle ID see What are app bundle IDs in iOS. For steps to create Redirect URL see below. | | Claim URL | String, Optional | API endpoint for assisted claiming. This is not applicable for customer deployments so it can be removed or kept empty. |

note

How to get ESP dashboard URL?

• ESP dashboard URL is in Cloudformation stack.
• Also, super admin gets the email after RM deployment.
• The mail gives the RM dashboard URL

App Configuration

Key	Type	Description
Enable Schedule	Bool	Enable(Yes) or Disable(No) scheduling functionality in the app.
Enable Scene	Bool	Enable(Yes) or Disable(No) scene feature in the app.

1. Terms of Use
2. Privacy Policy
3. Documentation

Provision Settings

Configuration related to the provisioning feature of the app.

Key	Type	Description
BLE Device Prefix	String	App will search for BLE devices with this prefix in the name.
ESP Allow Prefix Search	Bool	App will allow filtering by prefix search if this value is set to true. Filtering by prefix is not allowed otherwise.
ESP Security Mode	String	Possible values secure: for secure/encrypted communication between device and app. unsecure: for unsecured/unencrypted communication between device and app.
ESP Transport	String	Possible values BLE: supports only BLE device provisioning. SoftAP: supports only SoftAP device provisioning. Both: supports both BLE and SoftAP device provisioning.
ESP Scan Enabled	Bool	Enables or disables scanning feature in the app.

App Group

App groups allow multiple apps produced by a single development team to maintain shared container (storage space). In this particular case this container is shared between the app and the notification service extension. It is used to store Node details which is required by Notification service to customise notification message. Find more information on app groups here.

Configuring App Group

1. Go to apple developer console and into identifiers: https://developer.apple.com/account/resources/identifiers/list.
2. Add a new identifier by clicking on + button.
3. Select App Groups from the list and click on continue.

4. Add Description and Identifier for your app group and continue.

5. Review your changes and click on register to save it.

Configure App Group in Xcode

1. Open your Xcode project and go to Signing and Capabilties in main app target.
2. Under App Groups capabilities select the app group that you have configured earlier.

3. Repeat steps 1 and 2 for PushNotificationExtension target in app.
4. Open Configuration.plist file inside the project.
5. Provide your app group id as the value of the key App Group.

Push Notification Settings

Push notifications are enabled by default in the project. However, if you want to test notification at the time of development you need to change the endpoint from APNS to APNS_SANDBOX in the below method:

Note: Remember to change the platform back to APNS when you distribute your app or upload it to App Store.

Add URL Scheme

App Bundle ID should be included in the Info.plist file of the RainMaker Project. Click on ESPRainMaker -> Info Tab. Scroll down to URL Types and expand. Add your URL scheme as shown below.

Creating Redirect URL

Redirect URL for ESP RainMaker app will be

com.espressif.rainmaker.softap://success

Replace com.espressif.rainmaker.softap with your application Bundle ID in the above data. So Redirect URL for your app will be

com.your_application_id.app://success

Additional Setting

You can also provide a theme colour to your application by setting the value of App Theme Color key in Configuration.plist. Provide it with a hex value of the intended colour, for e.g. #FFFFFF.

Alexa Account Linking

This account linking flow enables users to link their Alexa user account with their account in another service by starting from app. The following sections cover the app side configuration for alexa account linking.

Note: For more information on account linking and the cloud configuration please go here.

Creating iOS Universal Links:

When you support universal links, iOS users can tap a link to your website and get seamlessly redirected to your installed app without going through Safari. If your app isn't installed, tapping a link to your website opens your website in Safari.

Please check iOS documentation for Universal Links.

You can go through the following steps in order to create a universal link for your app:

1. In your app's Xcode project select the .xcodeproj file in the project navigator. In the Signing and Capabilites section, there is an Associated Domains section. Click on the + sign in the Domains section. Add the following information in that section: applinks:domain name of the associated website

2. Create the apple-app-site-association File

Create a file named apple-app-site-association. This file will contain the following JSON structure:

    {
    "applinks": {
     "apps": [],
        "details": [
        {
            "appID": "ABCD1234.com.apple.wwdc",
            "paths": ["*"]
        }
        ]
    }
    }

note

Do not add .json to the apple-app-site-association file.

3. The appID in the above file has the following format: TEAMID.Bundle ID of your app. Find more information on Team ID here and more information on app Bundle ID here.

4. The paths array contains the list of paths for your website for which the app supports universal links. The * value for paths means that all possible paths for your website are supported.

5. This apple-app-site-association file has to be placed in the root directory of your server or in the .well-known folder in the root directory of your server.

6. The file needs to be accessible via HTTPS—without any redirects—at https://<domain>/apple-app-site-association or https://<domain>/.well-known/apple-app-site-association.

7. You can validate your universal link using https://branch.io/resources/aasa-validator
