-Xcode 8 is here if you have not peeked at any of betas yet, you will find all kinds of new stuff.

We have also received simplified Core Data stack in form of NSPersistentContainer that does heavy part of setup for us. Is it worth trying? Let's dig in and find out.
+Xcode 8 已经面世了，如果你还没有尝试过这个抢鲜测试版本，你会发现所有新的东西。这里有 Swift 4 [主要的更新](https://swifting.io/blog/2016/08/17/22-swift-3-access-control-beta-6?utm_source=swifting.io&utm_medium=web&utm_campaign=blog%20post)，有新的框架，比如 [SiriKit](https://swifting.io/blog/2016/07/18/20-sirikit-can-you-outsmart-provided-intents?utm_source=swifting.io&utm_medium=web&utm_campaign=blog%20post) 和一些对现存特性的增强改进，比如 [notifications](https://swifting.io/blog/2016/08/22/23-notifications-in-ios-10?utm_source=swifting.io&utm_medium=web&utm_campaign=blog%20post). 我们也接收以 `NSPersistentContainer` 形式的简化版的 `Core Data` 堆，它为我们做了大部分的准备工作。它值得我们去尝试么？让我们开始深入挖掘这些新特性吧。


如果你还没有尝试过这个测试版本，你将会发现各种新东西。

notifications 这句后面为句号。

Xcode 8 正式版已经发布，如果你之前没尝试过beta版本，那么你会大呼过瘾，新东西很多。Swift 3[重磅更新]、各种新框架[比如SiriKit]、以及对现有框架的改进[比如notifications]。
还有简化 Core Data stack 设置的 NSPersistentContainer 类。／还有新的 NSPersistentContainer 类，极大简化了 Core Data stack 的使用。

这里有 - there is 这里是表示存在的意思，不必翻译成【这里有】，语句还是符合汉语习惯比较好。
我们也接收以 - We have also received 这里 We have ... received 表示的也是存在的意思，【我们】不必翻译出来。
does heavy part of setup - 这里我认为可以用意译。
stack 是一个术语，应该和 Core Data 联用，我认为不必写成汉字。

+多年来，在尝试了很多种 Core Data 堆之后，我们选定了两个简单的堆，融合成一个使用。
这句严重理解错误。我试着提供一种理解，并不是经过斟酌的译文，当然要翻译得简洁有难点，但是最重要的是【准确】：
长期以来，尝试过多种Core Data Stack配置方式之后，我们认定了一种简单的配置方式：两个context的stack架构，一个context保存(save)时，另一个context合并(merge)变化。

附原文：Over years, after trying many Core Data stacks we have settled on simple two context stack with a merge on save.

完整版本的 Github “连接” 在引用中能找到。——链接而非连接。

after trying many Core Data stacks we have settled on simple two context stack with a merge on save. @owenlyn 你看一下这句的翻译。

(after trying many Core Data stacks) (we) (have settled) (on simple two context stack with a merge on save).

按照句子成分来看，我觉得翻译的挺符合作者原意的。不过按正常的英文形容词的顺序，原文应该是 "two simple context stack" 。然后我看了一下作者，他母语应该不是英语...

+从 `NSURL` 文档中获得 `getter` 方法。`NSPersistentStoreCoordinator` 使用它在给定的位置创建 `NSPersistentStore`。  



Extracted documents directory NSURL getter

建议翻译成

获取文档路径 NSURL 的 getter。

这里 Extracted documents directory 和 NSURL 应该是同位语吧？
“getter” 翻译成 “获取方法” 是不是会有歧义？所以保留不翻是不是更好？@Graning
