Xamarin.iOS.StoreKit2Sample

This is a sample how to leverage StoreKit2 in Xamarin.iOS. Extend to your needs.

Add required methods in StoreKit2/StoreKit2/AppStoreManager.Swift

The methods need to be objc compatibile (@objc), class has to derive from NSObject so it can be consumed from objc. I just added showManageSubscriptions because this is the only method I needed in my project.

Build release in xcode for Debug and Release.

Create xcframework so it works on both iPhone and simulator.

xcodebuild -create-xcframework -framework path-from-your-xcode-derived-path/Release-iphoneos/StoreKit2.framework -framework Release-path-from-your-xcode-derived-path//StoreKit2.framework -output ./StoreKit2.xcframework

Download latest objective sharpie pkg

https://github.com/xamarin/xamarin-macios/blob/main/Make.config#L234C1-L235C1

Generate ApiDefinitions / enums

sharpie bind ..../Release-iphoneos/StoreKit2.framework/Headers/StoreKit2-Swift.h --sdk iphoneos16.2

Copy this to Xamarin bindings project (see sample attached)

Generate and consume nuget package

Take a look at .nuspec and .target file. This is required so .xcframework is properly included in your iOS project.

Notes

There is Xamarin iOS bug that prevents async swift methods working on simulator. It works on real device though which is enough for StoreKit. xamarin/xamarin-macios#18562
