The latest updates to dyld (the dynamic linker) were not specifically mentioned in the provided context from WWDC. However, there are several related improvements in Xcode 16 and Swift that could impact the build and debugging processes, which dyld is a part of:
-
Explicit Modules: Xcode 16 introduces explicit modules, which improve parallelism, diagnostics, and debugging speed. This can lead to more predictable and reliable builds, as well as faster debugging since the debugger can share binary modules with the build. This is discussed in the session What’s new in Xcode 16.
-
DWARF 5: Xcode 16 now uses DWARF 5 as the default debug symbol format, which results in smaller DSIM bundles and faster symbol lookups. This can improve the overall debugging experience, which is closely related to how
dyldhandles symbol resolution. This is mentioned in the session What’s new in Xcode 16. -
Thread Performance Checker: Enhancements to the thread performance checker in Xcode 16 now include diagnostics for excessive disk writes and slow app launches, which can help developers optimize their apps' performance. This is covered in the session What’s new in Xcode 16.
For more detailed information on these topics, you can refer to the sessions mentioned above. If you have specific questions about dyld that were not covered here, it might be useful to check the full WWDC session videos or Apple's developer documentation.
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.
