Xcode 6 introduced several changes to its project setup, one of which was the absence of an automatically generated ProjectName-Prefix.pch file. This change has led many developers to question the relevance of precompiled headers and how to adapt their workflow accordingly. This guide aims to clarify these changes and provide actionable solutions for developers accustomed to using prefix headers.
Why the Change?
The shift away from automatically creating a precompiled header file in Xcode 6 is largely due to the introduction of modules. Modules eliminate the need for certain imports, such as #import <Cocoa/Cocoa.h>, thereby simplifying code management and reducing build times. However, this change does not mean that precompiled headers are obsolete; they can still be utilized if necessary.
Creating a Custom PCH File
If your project requires a precompiled header, you can manually create and configure one by following these steps:
- Add a new PCH file to your project: Go to New File > Other > PCH File.
- In the Target’s Build Settings, set the Prefix Header path to your PCH file name, using the format
ProjectName/YourPCHFileName.pch. You can use placeholders like$(SRCROOT)or$(PROJECT_DIR)to define the path. - Set the Precompile Prefix Header option to YES.
Best Practices for Imports and Macros
Instead of relying on a prefix header for all imports, it’s recommended to:
- Import necessary headers directly into each file that requires them, ensuring clear dependencies.
- Avoid using macros unless absolutely necessary. If needed, place them in a dedicated header file.
This approach aids in maintaining a clean architecture and facilitates code reuse across different projects.
Enhancing Workflow with Automated Testing Tools
