Xcode is running really slow
提问by Richard Wessels
I've recently tried to use Xcode 8 to make iOS apps and to test things in Swift however it is impossible to work on as doing a simple 'print("Hello World")' takes easily over a minute to process to print it to the console, I tried doing regular development as well by creating UI buttons etc. but when I try to compile it, it is too slow to work and that is with simple things. My computer is the Mid 2012 Macbook Pro Non-retina with 4GB of RAM, not a quick computer but I can program in Python without these problems. If anyone knows some solutions please tell me! Thanks.
我最近尝试使用 Xcode 8 来制作 iOS 应用程序并在 Swift 中测试东西，但是这是不可能的，因为做一个简单的“打印（“Hello World”）”需要一分钟多的时间来处理打印到控制台，我也尝试通过创建 UI 按钮等来进行常规开发，但是当我尝试编译它时，它的工作速度太慢了，这就是简单的事情。我的电脑是 2012 年中期的 Macbook Pro Non-retina，有 4GB 的 RAM，不是一台快速的电脑，但我可以用 Python 编程而不会出现这些问题。如果有人知道一些解决方案，请告诉我！谢谢。

When you build a project for the first timedo it normally (it will take a while like you described)
当您第一次构建项目时，请正常进行（像您描述的那样需要一段时间）
After the first build Go to Product -> Scheme -> Edit Scheme. Select Buildin left side column and uncheck Find implicit dependencies.
第一次构建后转到Product -> Scheme -> Edit Scheme。选择Buildin left side column 并取消选中Find hidden dependencies。
