Remote Config

Provides remote configuration for iOS applications.

How it works

The module fetches a JSON config from the backend API at launch time and caches the config locally if the payload signature verification succeeds. The config is fetched and cached every 60 minutes by default.

Getting started

Requirements

This module supports iOS 10.0 and above. It has been tested on iOS 10.0 and above.

It is written in Swift 5.0 and can be used in compatible Xcode versions.

Documentation

Generated documentation for the module is hosted on rakutentech's GitHub site https://rakutentech.github.io/ios-remote-config.

Installing

To use the module your Podfile should contain:

source 'https://github.com/CocoaPods/Specs.git'

pod 'RRemoteConfig'

Run pod install to install the module and its dependencies.

Configuring

Currently we do not host any public APIs but you can create your own APIs and configure the SDK to use those.

To use the module you must set the following values in your app's Info.plist.

Key	Value (String type)
RASApplicationIdentifier	your_app_id
RASProjectSubscriptionKey	your_subscription_key
RRCConfigAPIEndpoint	https://www.example.com

Get config values

• Attention: Newly fetched config values will not be available until the next app launch. This means that in the first session after app install the fallback values will be used instead of fetched values.

Code examples

    // Get a String value
    let testString = RemoteConfig.getString(key: "stringKeyName", fallback: "string_fallback_value")

    // Get a Boolean value
    let testBoolean = RemoteConfig.getBoolean(key: "booleanKeyName", fallback: false)

    // Get a NSNumber value
    let testNumber = RemoteConfig.getNumber(key: "numberKeyName", fallback: 1)

    // Get the entire config as a dictionary
    let configDictionary = RemoteConfig.getConfig()

Advanced features

Configure polling delay

The polling delay (which defaults to 60 mins) can, optionally, be configured in the app's Info.plist:

Key	Value (Number type)
RRCConfigFetchPollingDelayInSeconds	delay in seconds

Note that the minimum polling delay is 60 seconds. If you try to set a lower value, the polling delay will be 60 seconds.
