Classes
The following classes are available globally.
-
The entry point of Firebase SDKs.
Initialize and configure
FirebaseApp
usingFirebaseApp.configure()
or other customized ways as shown below.The logging system has two modes: default mode and debug mode. In default mode, only logs with log level Notice, Warning and Error will be sent to device. In debug mode, all logs will be sent to device. The log levels that Firebase uses are consistent with the ASL log levels.
Enable debug mode by passing the
-FIRDebugEnabled
argument to the application. You can add this argument in the application’s Xcode scheme. When debug mode is enabled via-FIRDebugEnabled
, further executions of the application will also be in debug mode. In order to return to default mode, you must explicitly disable the debug mode with the application argument-FIRDebugDisabled
.It is also possible to change the default logging level in code by calling
FirebaseConfiguration.shared.setLoggerLevel(_:)
with the desired level.Declaration

A Timestamp represents a point in time independent of any time zone or calendar, represented as seconds and fractions of seconds at nanosecond resolution in UTC Epoch time. It is encoded using the Proleptic Gregorian Calendar which extends the Gregorian calendar backwards to year one. It is encoded assuming all minutes are 60 seconds long, i.e. leap seconds are “smeared” so that no leap second table is needed for interpretation. Range is from 0001-01-01T00:00:00Z to 9999-12-31T23:59:59.999999999Z. By restricting to that range, we ensure that we can convert to and from RFC 3339 date strings.
