Usage

Import the TimelaneCombine framework in your code:

import TimelaneCombine

Use the lane(_) operator to profile a subscription via the TimelaneInstrument. Insert lane(_) at the precise spot in your code you'd like to profile like so:

downloadImage(at: url).
  .lane("Download: \(url.path)")
  .assign(to: \.image, on: myImageView)

Then profile your project by clicking Product > Profile in Xcode's main menu.

Select the Timelane Instrument template:

Inspect your subscriptions on the timeline:

Reference

`lane(_:filter:)`

Use lane("Lane name") to send data to both the subscriptions and events lanes in the Timelane Instrument.

lane("Lane name", filter: [.subscriptions]) sends begin/completion events to the Subscriptions lane. Use this syntax if you only want to observe concurrent subscriptions.

lane("Lane name", filter: [.events]) sends events and values to the Events lane. Use this filter if you are only interested in values a subscription would emit (e.g. for example subjects).
