Working effectively with Apple platforms at a corporate or business level includes not only infrastructure, but a mode of thinking that administrators have to adopt to find success. A mode of thinking that forces you to leave 30 years of IT dogma at the door. This book is a guide through how to integrate Apple products in your environment with a minimum of friction. Because the Apple ecosystem is not going away.You'll start by understanding where Apple, third-party software vendors, and the IT community is taking us. What is Mobile Device Management and how does it work under the hood. By understanding how MDM works, you will understand what needs to happen on your networks in order to allow for MDM, as well as the best way to give the least amount of access to the servers or services that's necessary. You'll then look at management agents that do not include MDM, as well as when you will need to use an agent as opposed to when to use other options. Once you can install a management solution, you can deploy profiles on a device or you can deploy profiles on Macs using scripts. With Apple Device Management as your guide, you'll customize and package software for deployment and lock down devices so they're completely secure. You'll also work on getting standard QA environments built out, so you can test more effectively with less effort. Apple is forging their own path in IT. They trade spots with Amazon, Google, and Microsoft as the wealthiest company to ever exist. And they will not be constrained by 30 or more years of dogma in the IT industry. You can try to shoehorn Apple devices into outdated modes of device management, or you can embrace Apple's stance on management with the help of this book. What You'll LearnDeploy profiles across devices effectively and securelyInstall apps remotely both from the app store and through custom solutionsWork natively with Apple environments rather than retrofitting older IT solutions Who This Book Is ForMac administrators within organizations that want to integrate with the current Apple ecosystem, including Windows administrators learning how to use/manage Macs, mobile administrators working with iPhones and iPads, and mobile developers tasked with creating custom apps for internal, corporate distribution.

Develop well-structured applications using tested techniques and patterns. When you start to develop an application, you not only have to think about the idea of the finished application, but also about how it will evolve as it is built. This book shows you how to plan for changes, scope creep, and for the possibility of other developers joining in. Start by learning what architecture patterns for an application are. Yoüll find out why it¿s important for your applications to be based on these patterns and which ones are the most common. Then yoüll look at the MVC as one of the best known and used patterns. Yoüll see how and when it can be implemented in your applications, as well as its advantages and disadvantages. From there, yoüll discover the first evolution of the MVC model: the MVP, which introduces a new layer (Presenter) to better manage views. The next evolution after that is the MVVM, which introduces the ViewModel layer and its connection withthe views through Data Binding. With those prominent patterns covered, yoüll read about VIPER and VIP, Architecture Patterns that seeks to make applications easily maintainable, modularized, and highly scalable. All of which are hallmarks of Clean Architecture. Architecture patterns have developed and evolved to give your applications solid foundations. Understanding these patterns, you will reduce the problems that may arise when modifying existing functions, adding new ones, or correcting errors that may arise in the development process.What You'll LearnCode cleanly with solid foundations Start your project ready to adapt and evolve as features and other developers are added Find and apply the right patterns for the best results Who This Book Is ForDevelopers with some programming knowledge who want to learn different architecturepatterns, those who already have more experience and are looking for a starting point on complex patterns such as VIPER or VIP, and beginner programmers

"Start taking better photos with your iPhone! I remember my first phone. It had a cord attached and was shaped like a popular animated character. You didn't surf the Internet on it. You didn't send text messages. You didn't check your email. And you definitely didn't take pictures on it! Times have changed, haven't they? Most people probably don't even have a camera that's not attached to their phones. iPhons don't match the quality of a DSLR camera-but they're certainly coming close. This book won't teach you how to be the next Ansel Adams, but it will teach things you probably never knew about the camera and photo app. Inside, I'll show you how to: Take and edit photos -- Organize photos -- Use different photo modes and lenes -- Use photographic styles -- And much more. If you are ready to get the most out of your iPhone camera, then read on! Note: this book is based off of the iPhone 14 Pro, which has photo features (notably ProRes) that are not available on other iPhones. I will point out when a feature might not work on your phone." --
