In Xcode, dSYM files (Debug Symbol files) are used to store debug symbols for your app. These symbols are essential for debugging because they map the binary code of your app back to the original source code, allowing you to see meaningful information like function names, variable names, and line numbers in crash reports and during debugging sessions.
From the context provided:
-
Run, Break, Inspect: Explore effective debugging in LLDB mentions that to get correct line number information with crash logs, you need to ensure that the dSYM bundle for that build is available. This is crucial for understanding the control flow of the program and for investigating crashes effectively.
-
What’s new in Xcode 16 highlights that with DWARF 5, dSYM bundles are smaller and symbol lookups are faster, which improves the debugging experience.
For more detailed information on how dSYM files are used in debugging, you can refer to the session Run, Break, Inspect: Explore effective debugging in LLDB (06:33).

What’s new in Swift
Join us for an update on Swift. We’ll briefly go through a history of Swift over the past decade, and show you how the community has grown through workgroups, expanded the package ecosystem, and increased platform support. We’ll introduce you to a new language mode that achieves data-race safety by default, and a language subset that lets you run Swift on highly constrained systems. We’ll also explore some language updates including noncopyable types, typed throws, and improved C++ interoperability.
