Xcode 26 Beta 5, specifically the Apple Silicon-only variant, has seen a significant reduction in size, with a 22% decrease in download size and a 25% reduction in on-disk install size, reflecting Apple's optimization efforts announced at WWDC 25. These improvements are part of broader efforts to enhance efficiency, including unbundling the Metal toolchain in Xcode 26.0 Beta 1, and are expected to extend to iOS and watchOS runtimes, as seen with similar savings already achieved in tvOS runtimes. Two download options are available for Xcode, catering to both Intel and Apple Silicon architectures, with the Apple Silicon-only version offering the most substantial size reduction.
