Working With Multiple Environments in Xcode
From Zero to App Store
Every Xcode project starts out with two build configurations, Debug and Release. The names of these build configurations speak for themselves. The Debug configuration is used to create debug or development builds. Builds destined for TestFlight and App Store are built using the Release configuration. Having a Debug and a Release configuration is sufficient for some projects. Most setups require more flexibility, though.

Code Signing With fastlane
From Zero to App Store
Most developers don't take pleasure in resolving code signing issues and that includes me. While managing certificates and provisioning profiles has become easier over the years, it can still be challenging. If you're working in a team or use a build server to create and distribute builds, then code signing can become complex.

Setting Up the Project
From Zero to App Store
Even though Xcode makes it simple to set up a project, there's more to it than choosing a template and clicking a few buttons. The workflow I use to set up a new project is straightforward and easy to follow. In this episode, I show you what it looks like.

Defining a Minimum Viable Product
From Zero to App Store
From Zero to App Store won't focus on running a business on Apple's platforms, but it touches on a few ideas and concepts that relate to business. This episode focuses on defining the first version of the product. In the startup community, this is often referred to as defining the minimum viable product or MVP for short.

Introduction
From Zero to App Store
From Zero to App Store is a series that journals the development of Cocoacasts for iOS and tvOS. With this series, I aim to offer a look inside the workflows and processes I use to build and ship software. This series aims to touch every aspect of mobile software development, including source control, continuous integration, release management, and App Store deployment. It goes well beyond writing code.

Using a Branching Strategy That Works
Tips and Tricks
I hope we can agree that source control is a necessity for every software project. The most popular option for Cocoa and Swift development is Git. I've been using it for many years and I continue to appreciate its power and simplicity every day. It's easy to pick up thanks to its gentle learning curve. If you're not comfortable using Git from the command line, then take your pick from the many native clients for iOS and macOS.

Applying Quality of Service Classes
Mastering Grand Central Dispatch
Quality of service classes are an integral component of Grand Central Dispatch. You know from the previous episode what they are and how to use them. In this episode, you learn how to efficiently apply quality of service classes.

Understanding Quality of Service Classes
Mastering Grand Central Dispatch
In the introduction of this series, I mentioned that Grand Central Dispatch operates at the system level. It has an overview of the processes running on the system and the resources that are available. When your application submits a block of work to a dispatch queue, it's up to Grand Central Dispatch to decide when that block of work is executed.

Beyond the Basics With Dispatch Work Items
Mastering Grand Central Dispatch
The previous episodes have illustrated that working with the DispatchWorkItem class is a bit more complex than submitting a block of work to a dispatch queue. But you get several benefits in return. Control and flexibility are the most important advantages of the DispatchWorkItem class. In this episode, I'd like to show you a few additional benefits if you choose to work with dispatch work items.

Managing Build Configurations in Xcode
Tips and Tricks
A brand new Xcode project defines two build configurations, Debug and Release. Most projects define one or more additional build configurations for various reasons. This isn't new and it's a good practice to use build configurations to tailor a build to the specific needs of the environment it's going to be deployed to.

Grand Central Dispatch and Memory Management
Mastering Grand Central Dispatch
We ended the previous episode with some bad news. We discovered that the current implementation of the ImageTableViewCell class is leaking DispatchWorkItem instances. Before we implement a solution, I have more bad news. The problem is more complex than it appears. There are several memory issues we need to address. Let's tackle them one by one.

Adding Flexibility With Dispatch Work Items
Mastering Grand Central Dispatch
You already learned quite a bit about Grand Central Dispatch in this series. Most developers stop once they have a good grasp of the fundamentals. That's unfortunate because Grand Central Dispatch offers a number of more advanced APIs that add even more power to Apple's concurrency library. This episode focuses on dispatch work items.
