Learn how to quickly spot issues where your code is being called from a background thread, when it should not.

See how this tool helps pinpoint memory issues - taking you right to the line of code where a retained object was instantiated.

When it’s impossible to insert a breakpoint into a chain of Combine methods, where you need it, Publisher’s “breakpoint” methods can come to your rescue.

Learn how easy it is to debug without having to tether your device to your Mac. It’s a necessity for the Apple Watch and TV, but works with all devices.
