DESCRIBE YOUR PR

Documents the experimental options.experimental.enableUIUpdateLinkFramesTracking option added in getsentry/sentry-cocoa#9541.

  • Adds the option to the Apple options reference under the experimental options.
  • Adds a "Tracking Frames Without Waking Up Your App" subsection under Slow and Frozen Frames that explains the default CADisplayLink behavior, what the UIUpdateLink based implementation does instead, how the reported values compare, and the supported OS versions, with Swift, Objective-C and SentryObjC snippets.

The option ships with the next sentry-cocoa release after 9.34.0. The pages say 9.35.0; adjust if the release number changes.

Do not merge before getsentry/sentry-cocoa#9541 is released.

IS YOUR CHANGE URGENT?

  • Urgent deadline (GA date, etc.): YYYY-MM-DD
  • Other deadline: YYYY-MM-DD
  • No deadline: Not urgent, can wait up to 1 week+

PRE-MERGE CHECKLIST

  • Checked Vercel preview for correctness, including links
  • PR was reviewed and approved by any necessary SMEs (subject matter experts)
  • PR was reviewed and approved by a member of the Sentry docs team

Add the experimental enableUIUpdateLinkFramesTracking option to the
Apple options reference and explain under Slow and Frozen Frames how
it tracks frames with the main run loop and a UIUpdateLink instead of
a CADisplayLink, so an idle app no longer wakes up for every frame.
