![]() The demo for this article is an iOS project that uses CocoaPods to manage dependencies. ![]() For this to work, you need to create a framework and add source files that you intend to work in Playground. Playground can’t access code in the same workspace, or parent project if the Playground is added as nested project. But if we are using CocoaPods then it is viable too. We can use Carthage to fetch custom framework and build it. Xcode 9 allows to import custom framework in Playground as long as the framework is in the same workspace as the Playground. That forces to think carefully about dependencies, so I can just import a particular screen and iterate on that in Playground. The scenario with Playground is that we only style one screen or component at a time. Or at least it depends on the development community. It is not rerendering immediately like React Native or Injection App, but hopefully it will be better over the years □ So I started using it successfully in some of the apps. But after seeing Kickstarter iOS app using Playground to faster their styling and development process, it impressed me a lot. I wasn’t very convinced at first, and I saw lots of complains about slow or unresponsive Playground. Together with the introduction of Swift in WWDC 2014, Apple also introduced Playground, which is said to be “a new and innovative way to explore the Swift programming language”. You also get a complete overview of all the possible UIs for each state. You make some changes and see the result immediately. React has hot reloader and Storybook which make it super fast to do UI iterations. If you work with React, you know that it is just merely UI representation of state UI = f(state).You get some data, you build a UI to represent it. It looks like the compiler is mining Bitcoin secretly while pretending to compile □ It makes us less efficient to do quick iteration. But the real pain lies in the compiling part, which takes the most time, and that is even worse with Swift. That process involves us changing code, compiling, waiting, checking, then changing code and much more…Tools like Flawless App helps to easily compare between result on iOS app and Sketch design. We mostly fetch JSON data from backend, parse it to model and then render it using UIView, mostly UITableView or UICollectionView.įor iOS, we need to continuously tweak the UI according to the design to make it fit small sized handheld devices. Most of the time, we can say that app is a prettifier of data. One of the tasks is to make sure the UI, the thing that users see, looks good and correct. ![]() Our mission as mobile developers is to provide the best user experience for the end users, to make life more engaging and easier for them through dedicated apps.
