iOS 位置管理器 - isAuthorizedForPreciseLocation 似乎不存在

Question

在 LocationManager 的 desiredAccuracy 中文档页面，苹果说

If your app isn’t authorized to access precise location information (isAuthorizedForPreciseLocation is false), changes to this property’s value have no effect; the accuracy is always kCLLocationAccuracyReduced.

我在任何地方都找不到这个属性，也没有关于它的文档。有人可以让我对此有所了解吗？

IOS 14
下载 Beta Xcode，我使用的是 12.0 版 beta (Swift)

   if #available(iOS 14.0, *) {
            if locationManager != nil {
                switch locationManager!.accuracyAuthorization {
                case .fullAccuracy:
                    print("Full Accuracy")
                case .reducedAccuracy:
                    print("Reduced Accuracy")
                @unknown default:
                    print("Unknown Precise Location...")
                }
            }
        }
