# init(bundleIdentifier:) Returns an instance of an `SBApplication` subclass that represents the target application identified by the given bundle identifier. ``` init?(bundleIdentifier ident: String) ``` ## Parameters `ident` A bundle identifier specifying an application that is OSA-compliant. ## Return Value An initialized shared instance of an `SBApplication` subclass that represents a target application with the bundle identifier of `ident`. Returns `nil` if no such application can be found or if the application does not have a scripting interface. ## Discussion If you must initialize an `SBApplication` object explictly, you should use this initializer if possible; unlike [`init(processIdentifier:)`](/documentation/ScriptingBridge/SBApplication/init(processIdentifier:)) and [`init(url:)`](/documentation/ScriptingBridge/SBApplication/init(url:)-6xbe5), this method is not dependent on changeable factors such as the target application’s path or process ID. Even so, you should rarely have to initialize an `SBApplication` object yourself; instead, you should initialize an application-specific subclass such as `iTunesApplication`. Note that this method does not check whether an application with the given bundle identifier actually exists. ## See Also [`applicationWithBundleIdentifier:`](/documentation/ScriptingBridge/SBApplication/applicationWithBundleIdentifier:) Returns the shared instance representing the target application specified by its bundle identifier. --- Copyright © 2026 Apple Inc.
