I'm using an xcode 7 playground, and I want to know how to make the playground display all the results printed out by a loop.
我正在使用xcode 7游乐场，我想知道如何让游乐场显示循环打印出的所有结果。
for example:
例如：
This will tell me the loop ran 4 times, but it will only display the last value of the iteration. Is there a way I can make it show all values?
这将告诉我循环运行4次，但它只显示迭代的最后一个值。有没有办法让它显示所有价值观？

In xcode 7, right clicking with a mouse on the display box will give you the correct dropdown menu. However, Ctrl-clicking with the track pad on a macbook will not give the correct dropdown menu. You have to select it under the Editor menu.
