Fast forward, when you mix c++ with swift on the c++ side there’s no precision issue.

The issue was resolved but the conversation was here https://stackoverflow.com/questions/21774899/voice-over-doesnt-read-phone-number-properly if there is no link after posting this then it was removed.

I originally reported this issue 12/17/2024 under FB16112960. The status says a potential fix has been identified.

Just branch and prepare your code base for Swift 6 instead of setting up the project for obsolescence.

This happens when you lock features behind a paywall the user wants access to. They pay, they get use of the feature, and then request a refund. If this happens in high volumes where the refunds exceed the total revenue, the above situation will arise, which means you have a wrong business model. Apple should provide an option where the developer can top up their app's sales balance, just like an overdrawn bank, to release it from the hold they place on the account or provide developers with an option not to offer refunds.

You can begin here: https://www.swift.org/documentation/cxx-interop/

You will just have to wait until it's released or you have placed an app or two into the store.

If it's not documented, then it's not supported - file a bug report, but this sounds like an overarching system service that cannot be altered.

No, you cannot prevent an app from launching via a deep link.

Never store passwords or pass anything in user defaults because it is not secured. If it's a homework assignment, then it's ok.

Your account is too new ...

Look into push notifications with a deep link or universal link.
