This module provide support for interfacing with an app’s marketplace, such as the Google Play Store for Android and the Apple App Store for iOS.

Currently, the framework provides the ability to request a store rating for the app from the user. In the future, this framework will provide the ability to perform in-app purchases and subscription management.

Setup

To include this framework in your project, add the following dependency to your Package.swift file:

let package = Package(
    name: "my-package",
    products: [
        .library(name: "MyProduct", targets: ["MyTarget"]),
    ],
    dependencies: [
        .package(url: "https://source.skip.tools/skip-marketplace.git", "0.0.0"..<"2.0.0"),
    ],
    targets: [
        .target(name: "MyTarget", dependencies: [
            .product(name: "SkipMarketplace", package: "skip-marketplace")
        ])
    ]
)

App Review Requests

You can use this library to request that the app marketplace show a prompt to the user requesting a rating for the app for the given marketplace.

import SkipMarketplace

// request that the system show an app review request at most once every month
Marketplace.current.requestReview(period: .days(31))

For guidance on how and when to make these sorts of requests, see the relevant documentation for the Apple App Store and Google PlayStore.

Listing and purchasing digital goods

Android Configuration

You must set the com.android.vending.BILLING permission in your AndroidManifest.xml file like so:

<manifest xmlns:android="http://schemas.android.com/apk/res/android">
    <uses-permission android:name="com.android.vending.BILLING"/>
</manifest>

Building

This project is a free Swift Package Manager module that uses the Skip plugin to transpile Swift into Kotlin.

Building the module requires that Skip be installed using Homebrew with brew install skiptools/skip/skip. This will also install the necessary build prerequisites: Kotlin, Gradle, and the Android build tools.

Testing

The module can be tested using the standard swift test command or by running the test target for the macOS destination in Xcode, which will run the Swift tests as well as the transpiled Kotlin JUnit tests in the Robolectric Android simulation environment.

Parity testing can be performed with skip test, which will output a table of the test results for both platforms.
