It crashes when I launch the app on iPHone6 iOS 12, but it doesn't crash on iOS 13

[zyestin]

Description

After the ipa package is generated in archive.
It crashed every time I opened the app, on iPhone 6 / iOS 12.
However, there's no problem in debug.

It is possible that the minimum iOS version supported by swift is 13

Expected Behavior

App launched normally

Solution
I found the solution here 👉🏻 dyld: Library not loaded: /System/Library/Frameworks/SwiftUI.framework/SwiftUI

Do as below

Key info
Why I found solution by search dyld: Library not loaded: /System/Library/Frameworks/SwiftUI.framework/SwiftUI ?
Because I suspected it was caused by the storekit2 api, I deleted the storekit2 api code in RNIapIosSk2.swift. Then I run the app using Xcode with release config. It crashed with more infomation as below.

error: '...' is not a valid command.

So it is clearly about swiftUI.
