To profile a macOS or iOS app, use the xctrace CLI with a Time Profiler template to record performance data, selecting the target binary to identify slow operations. This requires the xctrace tool and Instruments to capture trace data.

Yes, xctrace profiling can be run from the command line using the xctrace CLI. You can launch an app, apply a Time Profiler template, and export trace data directly without needing the graphical interface.

Use the Time Profiler template with xctrace by specifying the template name, time limit, and output path in your command. You must also launch the target binary to ensure accurate performance data collection during the recording.

Yes, selecting the correct binary or app instance is required for accurate xctrace performance data. Binary selection ensures the profiler captures stack analysis and execution metrics strictly for your target native app.

For resolving native app memory leaks, macOS profiling with xctrace and Instruments is recommended. It records detailed app performance data and stack traces to help identify slow operations and memory issues.

xctrace profiling requires the Instruments app because xctrace acts as its command-line interface. Instruments provides the underlying templates and data processing engine needed to record and export app trace files.
