DataDog/dd-sdk-ios 3.22.0 on GitHub

What's Changed

Flags: Add Flags.Configuration.flagSelection to load only the flags that match the given tags or key patterns. See #3344
Flags: Add per-subject experimentation opt-out through FlagsClient.Configuration.experimentationOptOutMode. The dd_experimentation_opt_out_at context attribute supports .immediate and .futureExperimentsOnly modes. Adds FlagsError.invalidContext and FlagEvaluationError.invalidContext; exhaustive switches need the new case. Timestamps use proleptic Gregorian dates with UTC year bounds. Filtered responses are rejected when no subject opt-out applies. See #3338

Fix profiler crashes during process-exit cleanup and when memory allocation fails during sample aggregation. See #3419
Flags: Send Flags.Configuration.customFlagsHeaders only to customFlagsEndpoint, not to the default Datadog endpoint. See #3442
Apply Session Replay textAndInputPrivacy overrides when masking UISwitch, UISlider, UIStepper, the selected segment of UISegmentedControl, and inline UIDatePicker. These controls previously used only the global privacy level. See #3407
Merge SDK baggage into existing first-party request headers during Trace URLSession tracking. See #3410
RUM operation step events now report the active view's name. See #3406
Avoid a Session Replay crash when Core Image cannot allocate an intermediate buffer. See #3384
Flags: Return the served value from Double reads, such as getDoubleValue and getDoubleDetails, of numeric flags with a whole-number value, for example 1. Before, these reads returned the default value with a .typeMismatch error and logged no exposure. See #3388
Stop reporting watchdog terminations into a RUM session stopped with stopSession(). Before, a watchdog termination after the stop was reported in the stopped session's last view. See #3352
Flags: Stop reporting assignment fetch failures as SDK defects and log them as warnings. See #3307

Send only new or grown slow frames in RUM view updates, and merge consecutive slow frames into one. See #3290
