  • This callback provides encrypted debugging information that can be used to help identify crashes. For example, if the client app uses Firebase Crashlytics, this can be passed along as follows:

    [[FIRCrashlytics crashlytics] log:debugInfo];

    Declaration

    Objective-C

    - (void)didOutputDebugInfo:(NSString *)debugInfo;

    Swift

    optional func didOutputDebugInfo(_ debugInfo: String!)

    Parameters

    debugInfo

    The encrypted debugging information

  • This callback provides debugging information as key value pairs. For example, if the client app uses Firebase Crashlytics, this can be passed as a custom attribute as follows:

    [[FIRCrashlytics crashlytics] setCustomValue:val forKey:key];

    Declaration

    Objective-C

    - (void)didOutputDebugKey:(NSString *)key withValue:(id)val;

    Swift

    optional func didOutputDebugKey(_ key: String!, withValue val: Any!)

    Parameters

    key

    Description of the type of debugging information
    val
