Testing in-app products on macOS

[setoelkahfi]

I'm testing in-app purchase feature on macOS with this plugin and local storeKit config. The iOS target is easily setup by opening the Xcode project and select the .storekit file in the iOS scheme.

How to do that for the macOS target? I tried to workaround the plugin, no luck so far.

StoreKit testing on macOS in Tauri is tricky because there is no Xcode project you can attach a .storekit configuration file to (unlike the iOS target where you open the generated Xcode project).

Here is what works:

1. Use the StoreKit Test environment via the command line

You can set the STOREKITTEST_STOREKIT_CONFIG environment variable to point at your .storekit file before launching your app:

export STOREKITTEST_STOREKIT_CONFIG=/path/to/your/Products.storekit
cargo tauri dev

This tells the StoreKit framework to use your local configuration instead of hitting the App Store sandbox. It works the same way Xcode passes the config — just through an environment variable rather than a scheme setting.

2. Run your debug build from Xcode (workaround)

If the env var approach does not work with the plugin you are using, you can create a minimal Xcode project that launches your compiled Tauri binary as its executable:

• Build with cargo tauri build --debug
• In Xcode, create a new macOS project (or a blank scheme)
• Under Scheme > Run > Info, set the Executable to your .app bundle from src-tauri/target/debug/bundle/macos/
• Under Scheme > Run > Options, select your .storekit configuration file
• Run from Xcode

This gives you the full StoreKit testing environment (transaction manager, simulated failures, etc.) while running your actual Tauri binary.

3. Sandbox entitlements

Make sure your src-tauri/Entitlements.plist (or Info.plist depending on your setup) includes the com.apple.security.app-sandbox entitlement, since StoreKit requires the app sandbox on macOS. Without it, the StoreKit API calls will silently fail even with the test config.

Hope that helps — let me know if you run into issues with any of these approaches.
