Years before, when we develop OS X program, we need to handle reference counter carefully. With the new technology of ARC. We don't need to do this anymore. However, I still love the old coding style which can develop fast and efficient programs.
During these years, more and more practical usage of Swift and released products written in Swift.
Swift is a powerful and intuitive programming language for macOS, iOS, watchOS and tvOS. Writing Swift code is interactive and fun, the syntax is concise yet expressive, and Swift includes modern features developers love. Swift code is safe by design, yet also produces software that runs lightning-fast.
Time is critical for all project manager. Rather than having fun in coding, we need to complete the job FAST and finished all the requirements by clients.
