What is RevenueCat?

RevenueCat is a secure, reliable, and free to use in-app purchase server with cross-platform support. With the RevenueCat SDK, you can build and manage your app business on any platform without having to maintain purchase infrastructure. You can read more about how RevenueCat fits into your app or you can sign up free to start building.

Requirements

Xcode 12+
Minimum target: iOS 9.0+

Installation

Purchases for iOS can be installed either via CocoaPods, Carthage, or Swift Package Manager.

Install via CocoaPods

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

pod 'Purchases'

Alternatively, pin to a specific minor version (e.g. 3.10):

pod 'Purchases', '~> 3.11.1'

And then run:

pod install

This will add Purchases.framework to your workspace.

Install via Carthage

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

github "revenuecat/purchases-ios"

Alternatively, pin to a specific minor version (e.g. 3.10):

github "revenuecat/purchases-ios" ~> 3.11.1

And then run:

carthage update

🚧

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.

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 and --no-use-binaries.

carthage update --no-use-binaries --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

Install via Swift Package Manager

You can use Swift Package Manager to add Purchases to your Xcode project. Select File » Swift Packages » Add Package Dependency... and specify the repository URL of the Purchases library: https://github.com/RevenueCat/purchases-ios.git. Set the version to Up to next major and 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.

Import Purchases

You should now be able import Purchases

import Purchases

#import "Purchases.h"
