Property wrappers are now supported for local variables. Creating variables that call a function of the same name. Multiple variadic parameters in functions. While this model mostly makes writing code in a playground very simple - we can just start writing in the global scope without the need to create app delegates or runloops or event handlers - it can make working on asynchronous code much harder. This is an Xcode playground that demonstrates the new features introduced in Swift 5.4: Improved implicit member syntax. Ultimately, they are just a tool to be used when it makes sense, but a very useful one. But, obviously, playgrounds are not meant to substitute the full blown Xcode IDE and the need to test on actual devices when developing a complete, functional app. Swift When you decide to use VIPER architecture in your project, it is very tired create new modules, because you need create at least 5 files for each. Swift-VIPER-Module - Xcode template for VIPER Architecture written in Swift 4. Each line of code is evaluated in an imperative manner, and once the last line has been executed, the program exits. The breaking news is that Xcode 8, currently in beta, will feature playgrounds for iPad. An Xcode playground demonstrating the new features in Swift 4.2. Just like command line tools and scripts, playgrounds are completely synchronous by default.

The Playground has a Sources and a Resources folder in which additional files can be stored. If not open already, click on the Navigator icon to show the sidebar. With this little workaround you’re now able to start prototyping, exploring and playing around with the given frameworks. The Playground opens with a simple 'Hello, playground' String in the main editor. Using Xcode Playgrounds to try out the Fiori for iOS SDK is great and makes it really simple to try out UIControls and other great APIs. Essential Developer: If you’re a mid/senior iOS developer who’s looking to improve both your skills and your salary level, then join the iOS Architect Crash Course, starting on March 28th. Xcode will create the Playground files and open the editor.
