independentwatchOSapplication.Inapppurchases

Bug Report

The problem is when i call function buy the product, the WatchOS (both simulator and real device) always shows message: unable to purchase app sign in with your apple id from the apple watch app on your iphone.
The store info works fine,

To Reproduce
Steps to reproduce the behavior:
1. use pod to install SwiftyStorekit

Expected behavior
I expect to see the 'purchase' flow.
I feel the problem is with that fact it's an independent watchOS app (no iphone needed)

NB:
If we think this is a restriction with independent watchOS app then I will remove it.
(eg for in app purchases to work on watchOS app, a watchOS app needed a companion iPhone app)
I wanted to make sure. Thanks

Platform Information

• OS: watcOS 7.0


• Purchase Type: non-consumable


• Environment: device, sandbox, emulator (I expect to see a dialog popup, but not work in emulator)


• SwiftyStoreKit: 0.16

Additional context
