Xcode Playground Timeline is empty

Question

I am trying to use the timeline assistant editor for a playground in xcode version 7.3.1, it is always empty. Timeline Appointment Editor

I think the error comes from xcode, however from the search it doesn't seem like anyone had the same error, so I got confused.

Answer 1

To display the result print, you need to open the "debug area" by going to the menu

View> Debug Area> Show Debug Area

or click the button in the lower left:

To display a timeline graph, you can use XCPCaptureValue:

import XCPlayground

var x = 0
for i in 0...10 {
    x += i
    print(x)
    XCPCaptureValue("Value for x", value: x)   
}

XCPCaptureValue ( ).
