Simulations in Swift 5 - Beau Nouvelle - Bog - APress - Plusbog.dk

Design and implement simulations using Apples Swift Playgrounds. Computer simulations are used to replicate the physical systems we see all around us. They help us solve problems by performing experiments that may otherwise be impossible in the real world. This book uses simulations to solve counter-intuitive logic puzzles, create procedural artworks, and build habitats for digital lifeforms. To help you create your own simulations using the Swift programming language, this book is filled with projects that you can easily follow along with. All you need is a Mac with the latest version of Xcode installed. All projects are written in Xcode''s Playgrounds. This keeps the process simple. No need to setup an Apple account, or learn anything further about building apps. Simulations are used in many areas within computer science and yet, barely anyone is teaching them. Sure, the fundamentals are in algorithm design, but simulations are a step above that. Usually when writing an algorithm you have a specific outcome in mind. However, when you create a simulation, the system you are modelling can be far more unpredictable than sorting a list, or navigating a maze. Simulations in Swift 5 will guide you through all of this. What You''ll Learn - Simulate situations with advanced algorithms to solve advanced problems - Incorporate real-world physics into simulated problems - Predict biological and other systems behavior and the outcome of events based on presented factors Who This Book Is For Swift programmers interested in tackling fun projects in Swift involving advanced algorithms and factors

Take advantage of the full power of Swift through XPC. Development for macOS differs from iOS and web-based development because of multicomponent applications. Besides the usual GUI-based applications and app extensions, there are a wide range of daemons—processes that run in the background—to worry about. These include system monitoring, event listening, notification agents, and many-many more. First, you''ll take a tour around different types of daemons: user agents, privileged helpers, login items, XPC services, and System Extensions. Knowing key specifics of the daemons will open a wide range of possibilities from non-trivial application development to system development. You''ll find lots of examples, working code samples, and even ready-to-use utilities. The book will guide you step-by-step through preparation, registration, and management of all kinds of daemons. System Extensions are brand new for macOS and open additional powerful features for developers.

Implementing iOS and macOS Documents with the Files App - Jesse Feiler - Bog - APress - Plusbog.dk

Implementing iOS and macOS Documents with the Files App - Jesse Feiler - Bog - APress - Plusbog.dk

Rise above the basics of Xcode app development to implement tools like Share buttons and activity view controllers to share document content including parts of documents with other users and with other devices. This book fills the gap so that developers with even a fundamental knowledge of iOS and Swift can implement document creation, saving, and sharing in their apps. Since the launch of iPhone in 2007, users and developers have struggled with the fact that the file system is hidden. Fortunately the Files app in iOS 11 now offers this feature and it is supported by Apple apps such as Numbers, Pages, and Keynote as well as by the few third-party apps that support documents. By using the standard formats described in this book, you can make your app''s data shareable to and from other apps like Numbers, Pages, and Word. Files also provides an interface to tools such as Dropbox and iCloud so that users can open and modify documents in them. If you combine standard formats such as .doc, .docx, .jpeg, and .jpg with Dropbox and eMail, you have a simple way to implement and use cross-platform sharing to Macs, PCs, and Android devices. Implementing iOS and macOS Documents with the Files App provides the combination of skills developers need to build these types of apps-working with files and constructing documents. What You''ll Learn - Add Document Support to Your Apps - Share your documents with iCloud and Apple IDs across your Mac and iOS devices - Use standard formats from .doc, .docx, .png, and .jpeg both for input and output - Manage and organize documents Who This Book Is For Developers with a basic knowledge of app development and Swift. You should already know how to use Xcode to create an app. Knowledge of basic Swift syntax is recommended. The book can also be a useful overview and guide to managers who are trying to decide how to convert legacy document-based systems to apps.

Great Big Agile - Jeff Dalton - Bog - APress - Plusbog.dk

Great Big Agile - Jeff Dalton - Bog - APress - Plusbog.dk

Big Agile leaders need an empirical, "high-trust" model that provides guidance for scaling and sustaining agility and capability throughout a modern technology organization. This book presents the Agile Performance Holarchy (APH)-a "how-ability" model that provides agile leaders and teams with an operating system to build, evaluate, and sustain great agile habits and behaviors. The APH is an organizational operating system based on a set of interdependent, self-organizing circles, or holons, that reflect the empirical, object-oriented nature of agility. As more companies seek the benefits of Agile within and beyond IT, agile leaders need to build and sustain capability while scaling agility-no easy task-and they need to succeed without introducing unnecessary process and overhead. The APH is drawn from lessons learned while observing and assessing hundreds of agile companies and teams. It is not a process or a hierarchy, but a holarchy, a series of performance circles with embedded and interdependent holons that reflect the behaviors of high-performing agile organizations. Great Big Agile provides implementation guidance in the areas of leadership, values, teaming, visioning, governing, building, supporting, and engaging within an all-agile organization. What You''ll Learn - Model the behaviors of a high-performance agile organization - Benefit from lessons learned by other organizations that have succeeded with Big Agile - Assess your level of agility with the Agile Performance Holarchy - Apply the APH model to your business - Understand the APH performance circles, holons, objectives, and actions - Obtain certification for your company, organization, or agency Who This Book Is For Professionals leading, or seeking to lead, an agile organization who wish to use an innovative model to raise their organization''s agile performance from one level to the next, all the way to mastery
