I am implementing the new StoreKit 2 api code in my app and came across a weird bug that appears to be in the Apple code. I've simplified it down and can recreate in the SKDemo code with one line.    func requestProducts() async { ...       for product in storeProducts { ...         case .autoRenewable:           let monthlyPriceFormat = product.priceFormatStyle ..   } Running this on either the iOS 15.5 simulator or a iOS 15.7 device causes a linker error on startup. dyld[96041]: Symbol not found: _$s8StoreKit12BackingValueO5value9atKeyPath8sentinel9transformxSSd_xyXKxSgACXEtlF  Referenced from: /Users/aUser/Library/Developer/CoreSimulator/Devices/B3B66803-93C2-41A7-A700-B6AF78C6CB60/data/Containers/Bundle/Application/07BBCBFC-EFFD-41B7-8C69-209E44AA4D4D/SKDemo.app/SKDemo  Expected in: /Library/Developer/CoreSimulator/Profiles/Runtimes/iOS 15.5.simruntime/Contents/Resources/RuntimeRoot/System/Library/Frameworks/StoreKit.framework/StoreKit Symbol not found: _$s8StoreKit12BackingValueO5value9atKeyPath8sentinel9transformxSSd_xyXKxSgACXEtlF  Referenced from: /Users/aUser/Library/Developer/CoreSimulator/Devices/B3B66803-93C2-41A7-A700-B6AF78C6CB60/data/Containers/Bundle/Application/07BBCBFC-EFFD-41B7-8C69-209E44AA4D4D/SKDemo.app/SKDemo  Expected in: /Library/Developer/CoreSimulator/Profiles/Runtimes/iOS 15.5.simruntime/Contents/Resources/RuntimeRoot/System/Library/Frameworks/StoreKit.framework/StoreKit The Product priceFormatStyle instance property is supposed to be available in iOS 15.0+ but doesn't appear to be there. It works fine on iOS 16.0 simulator and devices. The subscriptionPeriodFormatStyle instance property appears to have the same issue.
