Timelane is a free app that bundles a custom Xcode Instrument and the frameworks to enable your code to talk to the Timelane instrument. Once you start profiling your app with Timelane you will be able to see your asynchronous tasks plotted visually on an interactive timeline you can inspect to heart's content.
The app and related frameworks are free of charge. Additionally, anyone can use the Timelane core to enable their own asynchronous code to send profiling data to the Timelane Instrument.
Timelane is specifically designed to address profiling asynchronous concurrent code. Visualizing asynchronous operations gives you a bird's view over your subscriptions.
Drill down into the code to explore how it works. If you find a bug or have a suggestion, do say so. Made in the open by Marin Todorov.
