- (void)preflight:(nonnull TVOPreflightTest *)preflightTest
    didReceiveQualityWarnings:(nonnull NSSet<NSNumber *> *)currentWarnings
             previousWarnings:(nonnull NSSet<NSNumber *> *)previousWarnings;

Swift

optional func preflight(_ preflightTest: TVOPreflightTest, didReceiveQualityWarnings currentWarnings: Set<NSNumber>, previousWarnings: Set<NSNumber>)

Parameters

`preflightTest`	The `<TVOPreflightTest>` that received quality warning updates.
`currentWarnings`	An `<NSSet>` that contains the warnings at the instant of receiving this callback. Values in the `<NSSet`> are `<NSNumber>` with values of `<TVOCallQualityWarning>`.
`previousWarnings`	An `<NSSet>` that contains the warnings before receiving this callback. Values in the `<NSSet`> are `<NSNumber>` with values of `<TVOCallQualityWarning>`.

Swift

optional func preflight(_ preflightTest: TVOPreflightTest, didReceive statsSample: TVOPreflightStatsSample)

Parameters

`preflightTest`	The `<TVOPreflightTest>` that received the stats sample.
`statsSample`	The `<TVOPreflightStatsSample>`.
