When calling the verification interface for "whether the user belongs to a restricted region", the return value is always false; even if the Apple account is registered as an account belonging to a restricted region and the account is set to supervised mode, the interface return result remains unchanged, and it is impossible to verify a true result. The code for calling the interface is as follows:
@available(iOS 26.2, *) @objc public func eligibleForAgeFeatures() async -> Bool { var isEligible = false do { isEligible = try await AgeRangeService.shared.isEligibleForAgeFeatures } catch { isEligible = false } return isEligible }
