Xcode 6 - 防止快速游乐场刷新

Question

Sometimes I'm writing some code on a playground that takes a while to complete. For example:

var values = [[Int]](count: 10000, repeatedValue: [Int](count: 73, repeatedValue: 0))

And everytime the playground wants to refresh the results, it has to run that piece of code (that takes a while to run) and it makes Xcode as a whole very sluggish.

I still want to be writing my code on a playground since it has some very nice features for testing your algorithms. However, I'm finding that I have to comment certain lines of code just to continue writing without interruptions.

Is there any way to say to Xcode: "Do not run my playground right now. I'll tell you when it's ready."?

Answer 1

In Xcode 7, you can choose between automatic or manual execution of a playground by clicking and holding the ► arrow at the bottom left part of the playground.

我不知道这样做的正式方法，但是......如果你在游乐场的底部留下多行评论并且不添加结束* /标记，那么在添加结束标记之前它不会运行。
