# immediate(name:priority:executorPreference:operation:) Create and immediately start running a new task in the context of the calling thread/task. ``` @discardableResult static func immediate(name: String? = nil, priority: TaskPriority? = nil, executorPreference taskExecutor: consuming (any TaskExecutor)? = nil, operation: sending @escaping @isolated(any) () async -> Success) -> Task ``` ## Parameters `name` The high-level human-readable name given for this task `priority` The priority of the task. Pass `nil` to use the [`basePriority`](/documentation/Swift/Task/basePriority) of the current task (if there is one). `taskExecutor` The task executor that the child task should be started on and keep using. Explicitly passing `nil` as the executor preference is equivalent to no preference, and effectively means to inherit the outer context’s executor preference. You can also pass the [`globalConcurrentExecutor`](/documentation/Swift/globalConcurrentExecutor) global executor explicitly. `operation` the operation to be run immediately upon entering the task. ## Return Value A reference to the unstructured task which may be awaited on. ## Discussion This function *starts* the created task on the calling context. The task will continue executing on the caller’s context until it suspends, and after suspension will resume on the adequate executor. For a nonisolated operation this means running on the global concurrent pool, and on an isolated operation it means the appropriate executor of that isolation context. As indicated by the lack of `async` on this method, this method does *not* suspend, and instead takes over the calling task’s (thread’s) execution in a synchronous manner. Other than the execution semantics discussed above, the created task is semantically equivalent to a task created using the `Task/init(name:priority:operation:)` initializer. --- Copyright © 2026 Apple Inc.
