Introduction

As a C++ programmer, you're likely familiar with the importance of code formatting and style. Recently, you've made the switch to Xcode from CLion, but you're finding the default K&R brace style to be uncomfortable to work with. In this article, we'll explore how to configure Xcode to use the Allman brace style, which is a more widely accepted and readable format.

What is Allman Brace Style?

The Allman brace style is a coding convention that places the opening and closing curly braces on the next line, with the code inside the block indented. This style is named after Eric Allman, a well-known programmer who popularized this format in the 1980s. The Allman brace style is widely used in many programming languages, including C, C++, and Java.

Why Use Allman Brace Style?

So, why should you use the Allman brace style? Here are a few reasons:

  • Readability: The Allman brace style makes your code more readable by clearly defining the scope of each block of code.
  • Consistency: Using a consistent coding style throughout your project makes it easier for others to understand and maintain your code.
  • Industry standards: The Allman brace style is widely accepted and used in many industries, making it a good choice for collaborative projects.
