Xcode 7 swift playground - missing timeline slider window

Question

I don’t see the timeline slider on the Xcode 7 playground. I created a new default project "hello world", following the instructions in the Help section "About playgrounds", and the "Timeline slide" does not appear at the bottom or bottom of the playground "or the" Time Field "window.

I tried various viewing options in the View menu and searched for help and www, no obvious answers.

Answer 1

If you open the project settings (right panel), you can see two parameters in the "Playground Settings" section (in the drop-down list for selecting a platform).

One of them is the "Render documentation", which changes the format of comments on the playground, so it looks more like a book or a web page with formatted code samples.

The second is “Show timeline”, which will return the slider in the window.
