Simple Excel Functions is a fantastic way to learn the common and not so common functions of Excel that will significantly improve your efficiency and effectiveness in solving data based problems. Each chapter has detailed descriptions of how the functions work, best practice and downloadable exercises that you can follow at home or at work.
The writing style keeps in mind that not everyone is a programmer and explains the functions in a language everyone can understand. Included are examples of situations where such functions can be put to good use.
This book covers iOS 11 app design fundamentals using the latest Swift 4 programming language, Xcode 9 and iOS 11 SDK.
The author assumes you have no experience in app development. The book starts with the installation of the required programming environment and setting up the simulators. Then, the simplest "Hello World" app is developed step by step. In the next chapter, basics of the Swift 4 programming language are given with practical examples. Screenshots and code snippets are clearly given in the book to guide the reader. After the Swift lecture, 7 real world apps are developed again by step by step instructions. Each code line is explained. As the reader follows the development of the example apps, he/she will learn designing user interfaces, connecting interface objects to code, developing efficient Swift code and testing the app in simulators and real devices.
