The term "dsym" refers to debug symbol files used in the context of debugging applications. At WWDC 2024, there were discussions about debugging improvements in Xcode 16, including the use of DWARF 5 as the default debug symbol format. This change results in smaller DSYM bundles and faster symbol lookups when building against certain deployment targets like macOS Sequoia or iOS 18. You can find more details about these debugging improvements in the session titled "What’s new in Xcode 16" under the chapter What's new in debugging.
