Apple Seeds Fourth Beta of tvOS 15.1 to Developers

Apple today seeded the fourth beta of an upcoming tvOS 15.1 update, one week after seeding the third beta and three weeks after the release of tvOS 15.

Developers can download the new tvOS 15.1 beta by downloading a profile onto the ‌Apple TV‌ using Xcode.

Other than new releases, tvOS updates are often minor in scale, focusing on under-the-hood bug fixes and improvements rather than major outward-facing changes. We don't yet know what's included in tvOS 15.1, but we'll update this article should anything be found.

Though we don't often know what's new in tvOS during the beta testing process, we let MacRumors readers know when new updates are available so those who are developers can download it upon release.

[SPOILER="tvOS 15.1 Beta 4 Release Notes"]
[HEADING=1]Overview[/HEADING]
The tvOS 15 SDK provides support to develop tvOS apps for Apple TV devices running tvOS 15.1 beta 4. The SDK comes bundled with Xcode 13, available from the Mac App Store. For information on the compatibility requirements for Xcode 13, see Xcode 13 Release Notes ('https://developer.apple.com/documentation/Xcode-Release-Notes/xcode-13-release-notes').

* NSExpression will immediately forbid certain operations that have significant side effects like creating and destroying objects. Additionally, casting string class names into Class objects with NSConstantValueExpression is deprecated. (84017178)
Workaround: Pass temporary objects to NSExpression in the context parameter of expressionValueWithObject:context: ('https://developer.apple.com/documentation/foundation/nsexpression/1410363-expressionvaluewithobject'), or with NSPredicate the substitutionVariables parameter of evaluateWithObject:substitutionVariables: ('https://developer.apple.com/documentation/foundation/nspredicate/1407759-evaluatewithobject'). You can create a derived predicate with all the substitution variables replaced (bound) using withSubstitutionVariables(_:) ('https://developer.apple.com/documentation/foundation/nspredicate/1413227-withsubstitutionvariables') on an existing NSPredicate so that code using the object can continue to use a simple evaluate(with object: Any?) invocation.
