问题
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.
for example:
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?
回答1:
Right click on the inline quick look (the gray rounded rectangle with "4" in it). There's an option to show all the results in a list:
You can also show everything that's been printed to the console for the entire playground execution by clicking the show debug area button all the way in the bottom left corner:

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.
This bug goes away in xcode 7.1

I attach GIF image for showing executing result of playground code.

You can see the results directly on the Debug Area
(or)
click anywhere on the line where your print method is defined and follow the below steps
1. Editor -> Show Results for Current Line Editor
2. Editor -> Result Display Mode -> Value History
Vice versa, you can hide the print details by
Editor -> Hide Results for Current Line
