For example, adding new parameters to a function with default values. Since we track SPI usage at the symbol level, this causes our allowlists to go out of date as the SDK changes, despite us not changing the Swift declarations we bind to. It would be helpful to have a higher-level way to describe the Swift interfaces we are using. 2190636 1 emw 2026-03-16 10:29:28 -0700 <rdar://problem/171546166> 2190637 2 emw 2026-03-16 10:30:14 -0700 Pull request: https://github.com/WebKit/WebKit/pull/60706 2190650 3 webkit-bug-importer 2026-03-16 11:08:35 -0700 <rdar://problem/172677139> 2198256 4 ews-feeder 2026-04-08 22:46:07 -0700 Committed 310820@main (8a4f2c1e1043): <https://commits.webkit.org/310820@main> Reviewed commits have been landed.
