Using Xcode Playground captureValue()
I'm using Playgrounds in Xcode 7.1 (beta 3) but having trouble with the captureValue() function:
captureValue:withIdentifier: Captures a value to be displayed with the specified identifier in the timeline.
Declaration
public func captureValue(value: T, withIdentifier identifier: String)
When I call the function, all I get is this:
How do I use captureValue? Or is this a bug in beta 3?
captureValue() displays the value you capture in the Timeline, which is a separate view that shows up in a playground's Assistant Editor. (You can show the Assistant Editor by pressing Command-Option-Return.) What you're showing is the result of the current line, which, since captureValue() returns Void, is just the XCPlaygroundPage itself.
Here's what the Timeline should look like:
