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.

* 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.
