Get quick answers for developing and debugging applications with Swift, Apple’s multi-paradigm programming language. This pocket reference is the perfect on-the-job tool for learning Swift’s modern language features, including type safety, generics, type inference, closures, tuples, automatic memory management, and support for Unicode. Designed to work with Cocoa and Cocoa Touch, Swift can be used in tandem with Objective-C, and either of these languages can call APIs implemented in the other. Swift is still evolving, but it’s clear that Apple sees it as the future language of choice for iOS and OS X software development. Topics include: Swift’s Run-Eval-Print-Loop (REPL) and interactive playgrounds Supported data types, such as strings, arrays, and dictionaries Variables and constants Program flow: loops and conditional execution Classes, structures, enumerations, functions, and protocols Closures: similar to blocks in Objective-C and lambdas in C# Optionals: values that can explicitly have no value Operators, operator overloading, and custom operators Access control: restricting access to types, methods, and properties Built-in global functions and their parameter requirements

If you use UNIX, you probably use csh to type commands even if you've never heard of it. It's the standard shell (command line) on most UNIX systems. tcsh is an enhanced version that's freely available and highly recommended.Using csh & tcsh describes from the beginning how to use these shells interactively. More important, it shows how to get your work done faster with less typing. Even if you've used UNIX for years, techniques described in this book can make you more efficient.You'll learn how to: Make your prompt tell you where you are (no more pwd) Use what you've typed before (history) Type long command lines with very few keystrokes (command and filename completion) Remind yourself of filenames when in the middle of typing a command Edit a botched command instead of retyping it This book does not cover programming or script writing in csh ortcsh because the tasks are better done with a different shell, such as sh (the Bourne shell) or a language like Perl.
