In this example, the executeTask method is a simple wrapper around another task: ‘async’ call in a function that does not support concurrency ‘async’ call in a function that does not support concurrency is a common error in Swift. The following error might be familiar to you already: We need a task to perform any async methods within a function that does not support concurrency. It’s important to understand that a job is executed directly after creation since it tells you only to create it when its work is allowed to start.Īpart from returning a value or throwing an error synchronously, tasks also execute async methods.
A task runs immediately after creation and does not require an explicit start. Well, the above examples already gave away the answer for this section. In other words, you can use a task to produce both a value and an error. Prints: Basic task failed with error: somethingIsWrong Print("Basic task failed with error: \(error)") This example returns a string but could also have been throwing an error: Prints: This is the result of the task We can use the reference to read out the outcome value:

How to create and run a TaskĬreating a basic task in Swift looks as follows:Īs you can see, we’re keeping a reference to our basicTask which returns a string value. If you’re new to async/await, I recommend first reading my article Async await in Swift explained with code examples.
