For me it works in Xcode 14.0 beta (14A5228q) if I select "Build" under "Test" in the Report Navigator, e.g. if I have: SchemeName Test Today, 15:00 Build Coverage Log ...after selecting "Build", the "Recent Build Timeline" assistant pane shows the timeline. Using the menus: Xcode / Editor / Assistant / Enable Xcode / View / Navigators / Reports Select "Local" tab Select a "Build" row You can use multi-touch on the trackpad to pan and zoom horizontally in the resulting graph.
