The Xcode 26.4 beta is out with some really cool features in Instruments! Instruments now has a new Run Comparison feature that allows you to compare call trees across runs so you can quickly verify your performance optimizations (or catch any regressions).

We also have a new Top Functions mode. This new top level mode on the call tree makes it really easy to identify the most expensive functions in the trace no matter where they are called from.

Best part is that these features can be used together to help you optimize your code!
