reportTransition
TypeScriptreportTransition(stateLabel?: (string) | null): voidSwift declarationfinal func reportTransition(to stateLabel: String?, stableMetadata: StableMetadata? = nil, volatileMetadata: VolatileMetadata? = nil)Reports a transition to a new state. A transition occurs only when `stateLabel` or `stableMetadata` changes from the current state. If both are equal to the current values, this call is a no-op. Pass `nil` for `stateLabel` to indicate that no state is currently active, clearing any previously reported state. Passing an empty string for `stateLabel` is a fatal error. Any volatile metadata from the previous state is discarded when a new transition begins. Calling this method more frequently than user interaction timescales can trigger rate limiting, causing state updates to go unlogged. - Parameters: - stateLabel: A descriptive label for the new state, which must not be empty, or `nil` to clear the active state. - stableMetadata: An optional value that identifies the state together with `stateLabel`. - volatileMetadata: An optional value providing context likely to change within this state.
