Classes

The following classes are available globally.

• HTTPMetric

  FIRHTTPMetric object can be used to make the SDK record information about a HTTP network request.

  Declaration

  Swift

  class HTTPMetric : NSObject, PerformanceAttributable

• Performance

  This class allows you to configure the Firebase Performance Reporting SDK. It also provides the interfaces to create timers and enable or disable automatic metrics capture.

  This SDK uses a Firebase Instance ID token to identify the app instance and periodically sends data to the Firebase backend. (see [FIRInstanceID getIDWithHandler:]). To stop the periodic sync, call [FIRInstanceID deleteIDWithHandler:] and either disable this SDK or set FIRPerformance.dataCollectionEnabled to NO.

  Declaration

  Swift

  class Performance : NSObject

• Trace

  FIRTrace objects contain information about a “Trace”, which is a sequence of steps. Traces can be used to measure the time taken for a sequence of steps. Traces also include “Counters”. Counters are used to track information which is cumulative in nature (e.g., Bytes downloaded). Counters are scoped to an FIRTrace object.

  Declaration

  Swift

  class Trace : NSObject, PerformanceAttributable
