Description

On an iOS device set to french FR/fr, RegionInfo.CurrentRegion.ISOCurrencySymbol returns XDR instead of EUR.
This happens only on the device, not on the simulator.

Also, when using standard resource strings on a device with FR language set, the culture stays in EN as if FR was not detected.

Device: iPhone XR, iOS 15.5

dotnet --version
6.0.400-preview.22330.6
VS 2022 Mac Preview 17.3.0.2089
with Xamarin.iOS 15.12.0.2

Steps to Reproduce

• Set the iPhone langage/region to FR (france)
• Start the maiu app in debug mode
• Observe the value of RegionInfo.CurrentRegion.ISOCurrencySymbol

I'm using MAUI iOS, not Xamarin @Eilon
Why did you moved that here ?*

It's working perfectly fine on Xamarin. It's a migrated app.

The code for both Xamarin.iOS and .NET iOS exists in this repo.

I couldn't figure out the best area label to add to this issue. If you have write-permissions please help me learn by adding exactly one area label.

So RegionInfo.CurrentRegion.ISOCurrencySymbol is a BCL API (System.Globalization) and not part of macios.

I believe https://developer.apple.com/documentation/foundation/nslocale/1642836-currencycode?language=objc would be the standard way of looking this up on iOS.

I am going to move this issue to dotnet/runtime as they own the BCL API in question.

@steveisok could you please triage this one? Thanks!

[steveisok]

Similar to #70028. This is something we will address in .NET 8.

Workaround. I still don't understand why it needs 2 releases ...
It was working in Xamarin.

No workaround needed for Android. It just works as expected.

        public static string LocaleCurrency =>
#if IOS
            Foundation.NSLocale.CurrentLocale.CurrencyCode;
#else
            RegionInfo.CurrentRegion.ISOCurrencySymbol;
#endif

This is the same issue as mentioned in #73512 (comment)

It was fixed in the 6.0.6 runtime release, I verified the issue doesn't happen with this or a later version.
