Instructions for installing Purchases SDK for iOS

What is RevenueCat?

RevenueCat provides a backend and a wrapper around StoreKit and Google Play Billing to make implementing in-app purchases and subscriptions easy. With our SDK, you can build and manage your app business on any platform without having to maintain IAP infrastructure. You can read more about how RevenueCat fits into your app or you can sign up free to start building.

Requirements

Xcode 13.3.1+
Minimum target: iOS 11.0+

Install via Swift Package Manager

You can use Swift Package Manager to add Purchases to your Xcode project. Select File ยป Swift Packages ยป Add Package Dependency... and specify the repository URL of the Purchases library: https://github.com/RevenueCat/purchases-ios.git. Set the Dependency Rule to Up to next major, and the version number to 4.0.0 < 5.0.0. Finally, choose the target where you want to use it. The library should have been added to the Swift Package Dependencies section and you should be able to import it now.

Install via CocoaPods

To always use the latest release, add the following to your Podfile:

pod 'RevenueCat'

Alternatively, pin to a specific minor version:

pod 'RevenueCat', '~> 4.0.0'

And then run:

pod install

This will add RevenueCat.framework to your workspace.

Install via Carthage

๐Ÿšง

Note: We recommend using Carthage versions >= 0.37.
Carthage versions < 0.37 have a bug which makes using carthage update --no-use-binaries produce build issues on Xcode 12. More information on this issue is available here http://github.com/Carthage/Carthage/issues/3019.

To always use the latest release, add the following to your Cartfile:

github "revenuecat/purchases-ios"

Alternatively, pin to a specific minor version:

github "revenuecat/purchases-ios" ~> 4.0.0

Carthage with XCFrameworks

If you're using Carthage version >= 0.37, you can use Purchases as an XCFramework instead of a Universal Framework. This makes setup easier, since you don't have to set up build phases at all.
To use XCFrameworks with Carthage, you need to pass in --use-xcframeworks.

carthage update --use-xcframeworks

More information on using XCFrameworks with Carthage is available at https://github.com/carthage/Carthage/#building-platform-independent-xcframeworks-xcode-12-and-above

Under certain configurations, when debugging your app, using po to print objects to the console might result in an error "Couldn't IRGen Expression". If you run into this, one workaround is to add a single, empty Objective-C file to your project, and create a bridging header. There's more information on this issue here

Carthage with regular frameworks

Run:

carthage update

Import the SDK

๐Ÿ“˜

Objective-C Only Projects

You may need to add an empty Swift file and a bridging header to your project before compiling.

You should now be able to import RevenueCat.

import RevenueCat
@import RevenueCat;

// or

#import "Purchases.h"
