Alamofire is a great Swift library that simplifies making web requests. There are many open source libraries that can help with these two tasks. To perform a search and display the results, you’ll need to do two things: The brains of the operation are in DuckDuckGo.swift – well, they will be by the time you finish! At the moment, performSearch(for:completion:) is a lazy, good-for-nothing block of code. Note the two view controllers: SearchViewController provides a search bar for the user to perform a search and DefinitionViewController displays the definition of a search term. Open DuckDuckDefine.xcodeproj in Xcode and have a quick look. There’s one problem: It doesn’t perform any searches yet! It includes the basic skeleton of DuckDuckDefine, a simple tool to look up definitions and images using the DuckDuckGo API. Use the Download Materials button at the top or bottom of this tutorial to download the starter project. You’ll do this by building an app that provides definitions for search terms using the DuckDuckGo API. Upgrade your dependencies to different versions.Declare dependencies, installing and integrating them within a project.

Learn why and when to use a dependency manager and what makes Carthage different from other tools.Not only was Carthage the first dependency manager to work with Swift, but it’s also written in Swift! It exclusively uses dynamic frameworks, rather than static libraries. That’s where dependency managers come in.Ĭarthage is a simple dependency manager for macOS and iOS, created by a group of developers from GitHub. With so many libraries available, managing dependencies can get tricky. If you’ve tried some of these libraries, you know the value of using someone else’s code instead of reinventing the wheel. One of the great things about iOS development is the wide range of third-party libraries available to use. Update note: Felipe Laso Marsetti updated this tutorial for iOS 13, Xcode 11 and Swift 5.
