MotionEyes Animation Debug

Overview

Use MotionEyes as temporary observability for SwiftUI animation debugging and regression validation. Instrument targeted values and geometry, capture time-series logs, compare observed motion against expected motion, apply fixes or assertions, re-validate, and clean up all agent-added tracing.

Use This Skill When

• An animation moves in the wrong direction, starts too late, or ends too early.
• Opacity, offset, or position changes do not match expected timing.
• Two elements drift or desynchronize during a transition.
• ScrollView offsets jump, drift, or fail to restore.
• You need evidence from runtime motion values rather than visual guesses.
• You want to turn MotionEyes traces into UITest or regression assertions for timing, continuity, or backtracking.

Do Not Use If

• The problem is unrelated to SwiftUI animation or scroll behavior.
• You cannot reproduce the behavior in a simulator or device.
