|If I had to give this book a one word description, I would say it is 'balanced'. In the beginning of the book the author mentions that he does not want to right one of those books that list a little code and then explains the code, changes the code, explains those changes and so on and so on.
At first he scared me. I have read some insanely wordy programming and engineering books. I have a much harder time getting through those than the type the author described. I was afraid this book would be one of those that I don't get anything out of except war stories from the author's career. That would not be all bad if the stories had anything to do with the book. I am happy to report that is not what happened.
I found the author had just the right amount of discussion around the different language features he was covering. I thought that the offer had a very no nonsense approach to all the topic that he covered.
The book is broken down into four parts. Below I have listed the three different parts, and the chapters that they contain.
Part I: Introduction to Objective-C
Chapter 1. C, the Foundation of Objective-C
Chapter 2. More about C Variables
Chapter 3. An Introduction to Object-Oriented Programming
Chapter 4. Your First Objective-C Program
Part II: Language Basics
Chapter 5. Messaging
Chapter 6. Classes and Objects
Chapter 7. The Class Object
Chapter 8. Frameworks
Chapter 9. Common Foundation Classes
Chapter 10. Control Structures in Objective-C
Chapter 11. Categories, Extensions, and Security
Chapter 12. Properties
Chapter 13. Protocols
Part III: Advanced Concepts Chapter 14. Memory Management Overview
Chapter 15. Reference Counting
Chapter 16. ARC
Chapter 17. Blocks
Chapter 18. A Few More Things
Part IV: Appendices
Appendix A. Reserved Words and Compiler Directives
Appendix B. Toll-Free Bridged Classes
Appendix C. 32- and 64-Bit
Appendix D. The Fragile Base Class Problem
Appendix E. Resources for Objective-C
One thing I really liked about the book was that the author did not use ARC throughout the book. He decided that reference counting is a very important topic to understand. The logic is that you're going to have to work with legacy code that is not going to be using ARC. There's much more legacy code out there then there is new code. He does take the time to explain how ARC works later in the book and the advanced concepts part.
I thought that I would lightly skim the first few chapters that cover the foundation of Objective-C. But as I was skimming, I found the author's writing style very nice to read, and therefore I ended up reading it word for word.
I must admit that I have been using messaging for a while now, but I never really understood messaging within the Objective-C context until I read this author's explanation of it. The author also has excellent coverage of properties and all of the different ways they can be declared.
The chapter on blocks was also very well put together. The author starts out by explaining function pointers and the issues that you can run into using them. He then does a very thorough job of covering blocks.
Every chapter in the book is a gem and overall I found this author's writing style made the book very easy to read. This book will stay by my side. It's not only a good cover to cover read, it is also a very good reference.
I would recommend this book as the place to start for anyone coming from a different find which such as C# or Java, and also as the place to start for anybody looking to get into building applications with Objective-C.
Learning Objective-C 2.0: A Hands-on Guide to Objective-C for Mac and iOS Developers (2nd Edition)
We call it DevOps but much of the time there’s a lot more discussion about the needs and concerns of developers than there is about other groups. There’s a focus on improved and less isolated developer workflows. There are many discussions around collaboration, continuous integration and delivery, issue tracking, source code control, code review, IDEs, and xPaaS – and all the tools that enable those things. Changes in developer practices may come up – such as developers taking ownership of code ...

The rise of containers and microservices has skyrocketed the rate at which new applications are moved into production environments today. While developers have been deploying containers to speed up the development processes for some time, there still remain challenges with running microservices efficiently. Most existing IT monitoring tools don’t actually maintain visibility into the containers that make up microservices. As those container applications move into production, some IT operations t...

As Enterprise business moves from Monoliths to Microservices, adoption and successful implementations of Microservices become more evident. The goal of Microservices is to improve software delivery speed and increase system safety as scale increases. Documenting hurdles and problems for the use of Microservices will help consultants, architects and specialists to avoid repeating the same mistakes and learn how and when to use (or not use) Microservices at the enterprise level. The circumstance w...

For organizations that have amassed large sums of software complexity, taking a microservices approach is the first step toward DevOps and continuous improvement / development. Integrating system-level analysis with microservices makes it easier to change and add functionality to applications at any time without the increase of risk. Before you start big transformation projects or a cloud migration, make sure these changes won’t take down your entire organization.

You often hear the two titles of "DevOps" and "Immutable Infrastructure" used independently. In his session at DevOps Summit, John Willis, Technical Evangelist for Docker, covered the union between the two topics and why this is important. He provided an overview of Immutable Infrastructure then showed how an Immutable Continuous Delivery pipeline can be applied as a best practice for "DevOps." He ended the session with some interesting case study examples.

When you focus on a journey from up-close, you look at your own technical and cultural history and how you changed it for the benefit of the customer. This was our starting point: too many integration issues, 13 SWP days and very long cycles. It was evident that in this fast-paced industry we could no longer afford this reality. We needed something that would take us beyond reducing the development lifecycles, CI and Agile methodologies. We made a fundamental difference, even changed our culture...

Updating DevOps to the latest production data slows down your development cycle. Probably it is due to slow, inefficient conventional storage and associated copy data management practices. In his session at @DevOpsSummit at 20th Cloud Expo, Dhiraj Sehgal, in Product and Solution at Tintri, will talk about DevOps and cloud-focused storage to update hundreds of child VMs (different flavors) with updates from a master VM in minutes, saving hours or even days in each development cycle. He will also...

DevOps and microservices are permeating software engineering teams broadly, whether these teams are in pure software shops but happen to run a business, such Uber and Airbnb, or in companies that rely heavily on software to run more traditional business, such as financial firms or high-end manufacturers. Microservices and DevOps have created software development and therefore business speed and agility benefits, but they have also created problems; specifically, they have created software securi...

This week's news brings us further reminders that if you're betting on cloud, you're headed in the right direction. The cloud is growing seven times faster than the rest of IT, according to IDC, with a 25% spending increase just from 2016 to 2017. SaaS still leads the pack, with an estimated two-thirds of public cloud spending going that way. Large enterprises, with more than 1,000 employees, are predicted to account for more than half of cloud spending and have the fastest annual growth rate.

All clouds are not equal. To succeed in a DevOps context, organizations should plan to develop/deploy apps across a choice of on-premise and public clouds simultaneously depending on the business needs. This is where the concept of the Lean Cloud comes in - resting on the idea that you often need to relocate your app modules over their life cycles for both innovation and operational efficiency in the cloud. In his session at @DevOpsSummit at19th Cloud Expo, Valentin (Val) Bercovici, CTO of Soli...
