Debugging & Profiling Memory in Xcode
Master the art of diagnosing and fixing memory issues, crashes, hangs, and performance problems in C/C++ applications on macOS. This course teaches you to effectively use Xcode's powerful debugging and profiling tools, including libgmalloc, the leaks command, Memory Graphs, AddressSanitizer, crash reports, and Instruments (Allocations, Leaks, and Time Profiler), to ensure your applications are stable, responsive, and high-performing.
Course Description
This comprehensive course empowers C/C++ developers to effectively diagnose and resolve complex runtime issues—including memory errors, crashes, hangs, and performance bottlenecks—within the macOS environment. You'll gain practical expertise in leveraging Xcode's robust suite of debugging and profiling tools, including libgmalloc for detecting memory corruption, the leaks command-line utility for quick analysis, and visual tools like Memory Graphs. You will also work with AddressSanitizer to uncover subtle memory bugs, and use Instruments such as Allocations, Leaks, and Time Profiler to analyze memory usage and CPU behavior in depth.
Crucially, the course covers crash and hang analysis, where you'll learn to interpret crash reports, understand Mach exceptions, perform symbolication, and diagnose unresponsive applications using tools like sample and spindump. By the end, you will be equipped to systematically identify root causes and build stable, efficient, and high-performance C/C++ applications for Apple platforms.
