Apple Seeds Third Beta of tvOS 15 to Developers

I often think about using the Beta on my Apple TV. Is it worth installing it or not?

Nah. It's very much the same as always. Unless you have any issues or want to use eARC with HPs that is.

[SPOILER="tvOS 15 beta 3 Changes/Issues"]
New Features in tvOS 15 beta 3

* You can now access Product ('https://developer.apple.com/documentation/storekit/product')raw JSON data for custom decoding:

* Multiple Product.PurchaseOption ('https://developer.apple.com/documentation/storekit/product/purchaseoption') methods are now allowed. .custom(_:) was replaced with several new type methods, namely custom(key:stringValue:) ('https://developer.apple.com/documentation/storekit/product/purchaseoption/3856627-custom'), custom(key:numberValue:) ('https://developer.apple.com/documentation/storekit/product/purchaseoption/3856626-custom'), custom(key:boolValue:) ('https://developer.apple.com/documentation/storekit/product/purchaseoption/3856624-custom'), and custom(key:dataValue:) ('https://developer.apple.com/documentation/storekit/product/purchaseoption/3856625-custom').
* Subscript operators on Product ('https://developer.apple.com/documentation/storekit/product'), Transaction ('https://developer.apple.com/documentation/storekit/transaction'), and renewalInfo ('https://developer.apple.com/documentation/storekit/product/subscriptioninfo/status/3822294-renewalinfo') were removed, along with the nested Key enumerations.
* BackingValue and extensions adding initializers from BackingValue were removed. (79101606)

* A new type property unfinished ('https://developer.apple.com/documentation/storekit/transaction/3856631-unfinished') is now available on Transaction ('https://developer.apple.com/documentation/storekit/transaction') that returns signed information for any transactions where the app still needs to deliver content to the user. (79620896)

Known Issues

* Subscription renewals aren’t automatically pushed to your app through the StoreKit 2 APIs in the App Store sandbox environment. Transaction and renewal information may not be immediately available. (78463355)
* Purchases made using the Sandbox environment return VerificationResult.unverified(_:). (79053760)

Resolved in tvOS 15 beta 3

* When calling latest(for:) on Transaction, or accessing the latestTransactionproperty on a Product value, the system now correctly returns a transaction for the given product identifier. (79399941)
* Fixed an issue when calling finishTransaction(_:) ('https://developer.apple.com/documentation/storekit/skpaymentqueue/1506003-finishtransaction') on the SKPaymentQueue ('https://developer.apple.com/documentation/storekit/skpaymentqueue') failed. (79854926)
* The cases consented and notConsented of the Product.SubscriptionInfo.RenewalInfo.PriceIncreaseStatus ('https://developer.apple.com/documentation/storekit/product/subscriptioninfo/renewalinfo/priceincreasestatus') enumeration were replaced with Product.SubscriptionInfo.RenewalInfo.PriceIncreaseStatus.agreed ('https://developer.apple.com/documentation/storekit/product/subscriptioninfo/renewalinfo/priceincreasestatus/agreed') and Product.SubscriptionInfo.RenewalInfo.PriceIncreaseStatus.pending ('https://developer.apple.com/documentation/storekit/product/subscriptioninfo/renewalinfo/priceincreasestatus/pending'), respectively. (75888552)
* Fixed an issue with calling the type method products(for:) ('https://developer.apple.com/documentation/storekit/product/3851116-products') on Product that failed if it contained subscriptions that had no localized App Store information in App Store Connect. (79729867)
* Fixed an issue with currentEntitlements ('https://developer.apple.com/documentation/storekit/transaction/3851204-currententitlements') where the property on Transaction ('https://developer.apple.com/documentation/storekit/transaction')returned multiple VerificationResult ('https://developer.apple.com/documentation/storekit/verificationresult') for a single Product.ID ('https://developer.apple.com/documentation/storekit/product/id'). (79212054)

Logging
Known Issues

* For every process crash, tvOS generates two crash logs. (76650102)

Deprecations

* Support for cleartext HTTP URL schemes for Proxy Automatic Configuration (PAC) is now deprecated. Use only HTTPS URL schemes for PAC. This affects all PAC configurations, including, but not limited to, configurations set via Settings, System Preferences, profiles, and URLSession APIs such as connectionProxyDictionary ('https://developer.apple.com/documentation/foundation/urlsessionconfiguration/1411499-connectionproxydictionary') and CFNetworkExecuteProxyAutoConfigurationURL(_:_:_:_:) ('https://developer.apple.com/documentation/cfnetwork/1426392-cfnetworkexecuteproxyautoconfigu'). If you configure a cleartext HTTP PAC URL, the system may upgrade it to HTTPS during PAC file loads. Web Proxy Auto-Discovery (WPAD) Protocol via DNS isn’t affected. Dynamic Host Configuration Protocol (DHCP) Option 252 WPAD may attempt to upgrade cleartext HTTP URLs to HTTPS during PAC file loads. (61981845)

MapKit
Deprecations

* MKPinAnnotationView ('https://developer.apple.com/documentation/mapkit/mkpinannotationview') and MapPin ('https://developer.apple.com/documentation/mapkit/mappin') are deprecated in this beta. (78536295)

SharePlay
Resolved in tvOS 15 beta 3

* Fixed an issue that required the iOS device to be PIN-paired before sending SharePlay content to Apple TV. (76149579)
* You can now return a SharePlay handoff to iOS. (79160555)
* When you play new content on Apple TV in a FaceTime with two iOS devices, the content plays, and is now in sync on the device that’s not signed into the same Apple ID that’s on Apple TV. (79424124)

Swift
Resolved in tvOS 15 beta 3

* The async Task ('https://developer.apple.com/documentation/swift/task') APIs in macOS, watchOS, and tvOS no longer differ from the async Task APIs in iOS. (79378627)

SwiftUI
Known Issues

* AsyncImage ('https://developer.apple.com/documentation/SwiftUI/AsyncImage') in List ('https://developer.apple.com/documentation/SwiftUI/List') sometimes cancels image downloads prematurely. (78187465)
* Fixed an issue that caused a TextField ('https://developer.apple.com/documentation/SwiftUI/TextField') in a ForEach ('https://developer.apple.com/documentation/SwiftUI/ForEach') to update an incorrect text binding. (78168257)

Resolved in tvOS 15 beta 3

* Fixed an issue that if you created a Text ('https://developer.apple.com/documentation/SwiftUI/Text') view from an AttributedString ('https://developer.apple.com/documentation/foundation/attributedstring') that contained a morphology attribute and then interpolated the Text view inside a LocalizedStringKey ('https://developer.apple.com/documentation/SwiftUI/LocalizedStringKey'), the attributes of the AttributedString didn’t affect the displayed text. (76192084)
* You can now correctly push to a third screen after popping from a third screen in the navigation stack. (79076444)
* The Alert ('https://developer.apple.com/documentation/SwiftUI/Alert') modifier now correctly displays a passed-in message. (79252107)

Xcode

Workaround: Test your app’s MusicKit functionality on a physical device.
