Declaration

Swift

Swift

/// The current log configuration.
static var logConfiguration: LogConfiguration { get }

/// Configures log storage, rotation, and output behavior.
final class LogConfiguration: NSObject {
    /// The severity threshold. Defaults to `.info`.
    var level: LogLevel

    /// The active output destination. Defaults to `.xlfacility`.
    var destination: LogDestination

    /// Relative log directory under Documents. Defaults to `.aibuds/logs`.
    var logsDirectory: String

    /// Maximum single file size. Defaults to 10 MB.
    var maxFileSize: UInt64

    /// Maximum retained age in days. Defaults to 3.
    var logFileMaxAge: Int
}

Log Levels

level is the minimum severity recorded. Levels below it are discarded.

Level	Use
.verbose	Fine-grained execution tracing.
.debug	Development diagnostics.
.info	Normal progress and operational information.
.warn	A condition that may require attention.
.error	A failure that may still allow the app to continue.
.fatal	A critical failure that may terminate the app.
.mute	Disable all log output.

Destinations

Destination	Output	Export support
.console	Xcode debugger console	No
.oslogger	Apple unified logging through os_log	No
.file	Files under the configured Documents-relative directory	Yes
.xlfacility	AIBudsXLFacility persistence plugin	Yes, when plugin is installed

Usage Examples

Swift

Swift

import AIBudsLog
import AIBudsXLFacility

let configuration = AIBudsLogSDK.logConfiguration
configuration.level = .debug
configuration.destination = .xlfacility
configuration.logFileMaxAge = 7

AIBudsLogSDK.setXLFacilityPlugin(XLFacilitySDK.shared)

AIBudsLogSDK.logService.info(
    "SDK configured",
    subsystem: "com.example.app",
    category: "startup"
)

Objective-C

Objective-C

#import <AIBudsLog/AIBudsLog-Swift.h>
#import <AIBudsXLFacility/AIBudsXLFacility-Swift.h>

AIBudsLogConfiguration *configuration = AIBudsLogSDK.logConfiguration;
configuration.level = AIBudsLogLevelDebug;
configuration.destination = AIBudsLogDestinationXlfacility;
configuration.logFileMaxAge = 7;

[AIBudsLogSDK setXLFacilityPlugin:AIBudsXLFacilitySDK.shared];

[AIBudsLogSDK.logService info:@"SDK configured" subsystem:@"com.example.app" category:@"startup"];

Notes

• Destination selection is process-wide and replaces the previous destination; it is not a set of simultaneously enabled outputs.
• logsDirectory accepts a Documents-relative path. A leading slash is removed by the SDK.
• Values less than or equal to zero are ignored for maxFileSize and logFileMaxAge.
• The public SDK does not expose remote-server logging configuration or category enable/disable switches.
