A promise is a popular programming pattern for performing tasks in the background. A powerful syntax using closures lets you start a task and define success and failure handlers all in one place. Promises are used in many languages but Swift’s convenient closure syntax makes them especially pleasant. This talk explains when promises are useful and demonstrates how to use them in typical programming scenarios, including chaining promises together and aggregating results. Demos use Swift 3 and a popular third party library called PromiseKit.
