RUM iOS SDK changelog

Aug 10, 2026

iOS SDK 2.15.1

Fixed

Network requests reported from Flutter and React Native now carry the HTTP reason phrase in network_request_context.status_text (for example, "OK" or "Not Found"). Previously it was always empty on iOS while Android populated it.

Aug 9, 2026

iOS SDK 2.15.0

Improved

Every user-interaction event now carries interaction_context.is_masked_element (always present, boolean): the SDK's own observation that the interaction targeted content Session Replay masked. false also covers "could not resolve" — a hybrid payload with no coordinates, or no frame geometry to test the point against — so the flag under-reports rather than over-reports. Read it in beforeSend to implement policies stricter than the default redaction: drop the event, blank the coordinates, or rewrite the target. Learn more
setUserInteraction accepts an optional is_masked boolean, an authoritative masking verdict from a hybrid wrapper that owns its own masking (the Flutter plugin sets it). It overrides the SDK's geometry resolution and drives both the flag and inner-text redaction.
FlutterViewBitmap gained maskRects, the rectangles Dart masked in the delivered bitmap, in Flutter-view-local points. They merge into the captured frame's mask geometry, so tap markers over masked Flutter content are now suppressed on the same terms as native masks. A reused stale bitmap carries the rects of its own frame, never a newer frame's.
Fixed network requests reported from Flutter and React Native being exported with a constant duration of 1 ms. They now carry their real measured duration.
Interactions reported through the hybrid bridge (setUserInteraction — React Native, Flutter) are now redacted on the same terms as native taps. Previously the bridge payload's target_element_inner_text was copied verbatim, so a masked element's real text shipped in the clear: the redaction only ran on the swizzled native-touch path, which emits no span in hybrid mode. Only the inner text is redacted — identity fields and coordinates are reported as-is, matching the web SDK — and the masking is resolved from the payload's coordinates against the same frame geometry that suppresses the replay's tap marker.
Native tap redaction now also tests the tap point against the frame's mask geometry, closing two gaps: text of UIKit views masked by maskText/maskAllImages, and text under a SwiftUI .cxMask() overlay (a sibling, not an ancestor, so the view-tree walk could not see it). Both previously shipped their real text while their pixels and tap marker were masked.

Aug 6, 2026

iOS SDK 2.14.0

New

Buffered spans are now automatically flushed when the app enters the background, ensuring telemetry is uploaded before process suspension. The SDK uses UIApplication.beginBackgroundTask to extend the background time window and guarantee completion before the app is terminated.

Aug 5, 2026

iOS SDK 2.13.3

Improved

setUserContext now promotes the next exported event to a snapshot event, so the session's user information refreshes immediately instead of waiting for the next error, navigation, or one-minute interval — matching the browser SDK's behavior.
Masking now applies to everything inside a masked view, not just the view it was set on. Masking a container is enough to cover its contents, including individually tappable subviews. Learn more
Tapping inside a masked area no longer draws a tap marker in Session Replay, so a recording of a masked keypad no longer reveals which keys were pressed. The frame is still recorded, and interaction events still carry their touch coordinates.
User interaction events now report *** for the text of any view inside a masked area. Previously only the masked view itself was redacted, so a tap on a key inside a masked keypad sent the key's label in clear.
Redacted target_element_inner_text is now reported as *** rather than omitted, matching the Android SDK. This affects views rejected by shouldSendText, password fields, and fields with a sensitive textContentType, which previously sent no target_element_inner_text at all.

Aug 2, 2026

iOS SDK 2.13.2

Fixed

Fixed session sampling dropping buffered spans when the session rotates.

Jul 28, 2026

iOS SDK 2.13.1

Improved

Exposed isSessionSampledIn to the beforeSend callback, so you can filter events with awareness of whether the session is sampled in.
Added the optional labels parameter to the hybrid (React Native / Flutter) reportError overloads, matching the native API.

Jul 28, 2026

iOS SDK 2.12.0

Improved

reportError now takes optional data and labels parameters on every overload (exception, error, and message). You can attach structured context and event labels in the same call instead of pairing reportError with a separate log — data lands under error_context.error_custom_data, and labels merge into the error event's labels. Learn more

Jul 23, 2026

iOS SDK 2.11.2

Fixed

Session Replay now masks the navigation-bar title during view transitions, closing a leak where the title could appear unmasked mid-transition.

Jul 20, 2026

iOS SDK 2.11.1

Fixed

Session Replay now holds the last captured Flutter frame instead of black-filling the frame when a bitmap is unavailable.

Jul 20, 2026

iOS SDK 2.11.0

New

Crash-event delivery now survives process death, so a crash that terminates the app is still reported on the next launch.

Jul 19, 2026

iOS SDK 2.10.4

Fixed

The active view is now frozen onto spans at creation time, so view_context matches the view that was active when the event occurred.

Jul 14, 2026

iOS SDK 2.10.3

Fixed

On the hybrid network path, iOS now honors the Dart / React Native wire traceId, so the exported span matches the traceparent sent on the wire.

Jul 14, 2026

iOS SDK 2.10.2

Fixed

Crashes are now attributed to the session that crashed and to the crash-time timestamp, rather than to the session that reports them on the next launch.

Jul 9, 2026

iOS SDK 2.10.1

Fixed

The task span is now reused on resume, so the wire traceparent matches the exported span.

Jul 5, 2026

iOS SDK 2.10.0

New

Added the createNewSession() public API to rotate the session on demand.

Jun 24, 2026

iOS SDK 2.9.2

Fixed

On the hybrid (React Native / Flutter) path, a beforeSend edit to an editable cx_rum field (for example, redacting session_context.user_email or rewriting labels) was reflected in text.cx_rum but not in instrumentation_data.otelSpan.attributes: the encoded spans were uploaded verbatim after the callback, so the tracing mirror stayed stale and a redacted value still leaked through tracing. The OTEL attributes are now rebuilt from the edited cx_rum before upload — the same rebuild the native single-event path performs — so both destinations carry identical values.

Jun 16, 2026

iOS SDK 2.9.1

Fixed

Fixed Cold Start AVG reporting multi-hour values. Prewarmed launches (iOS spawns the process in the background ahead of user intent, flagged by ActivePrewarm) and other background launches (push/fetch/location) were measured from kernel process birth time and counted as cold starts. Prewarmed launches are now skipped, and any cold-start duration beyond a 60s ceiling is dropped as a background-launch artifact. Learn more

Jun 15, 2026

iOS SDK 2.9.0

New

Session Replay now emits a one-shot init log capturing its configuration when recording starts, so the active Session Replay settings are visible in the backend. Learn more

Jun 11, 2026

iOS SDK 2.8.0

Improved

Fixed SwiftUI text and images not being masked in session replay, where the synchronous UIView walk could not see inside SwiftUI hosting views (BUGV2-6045). As an interim fix, the Vision-based TextScanner (OCR) and ImageScanner maskAll (rectangle detection) pipeline stages are restored, scoped to captures whose scene contains a SwiftUI hosting view (URLEntry.containsSwiftUIContent). UIKit and Flutter capture paths are unchanged. OCR masking is probabilistic (for example, rows clipped at the viewport edge mid-scroll may escape recognition).
Fixed a session replay mask-skew bug where, during scroll animations, mask rects drifted 16–80+ px behind the text they covered (BUGV2-6045). Native-window capture now uses layer.render(in:) (the model layer) and collects mask rects synchronously in the same render pass.
Fixed Flutter content appearing as a transparent hole in session-replay frames. A new flutterViewBitmapProvider requests a pre-masked RGBA8888 bitmap from the Flutter plugin's Dart rasteriser, which captures and masks in a single synchronous frame slice.
Fixed the session replay capture timer silently never firing when initialised via Flutter's background MethodChannel task queue (background threads have no run loop). All SessionReplay entry points now dispatch to DispatchQueue.main.
Fixed session replay click frames not being detected on iOS 26: getClickPoint cast tap coordinates with as? Double, which no longer succeeds for a boxed CGFloat on iOS 26. Coordinates are now coerced from any numeric boxing (Double/CGFloat/Int/NSNumber).
Added SessionReplayOptions.flutterViewBitmapProvider: FlutterViewBitmapProvider?, a callback for Flutter hosts to supply pre-masked frame bitmaps per capture. Learn more

Jun 2, 2026

iOS SDK 2.7.0

Improved

Added a customAttributes: [String: Any]? parameter on the reportError(message:, stackTrace:, ...) and reportError(message:, obfuscatedStackTrace:, ...) overloads. Custom attributes now ride alongside the parsed stack frames on the emitted error event instead of being mutually exclusive with the stack trace (CX-44438).

May 12, 2026

iOS SDK 2.6.4

Fixed

The hybrid SDK path now honors excludeFromSampling (CX-40203).
