Xcode build configuration files have a .xcconfig file extension. They allow build settings for your app to be declared without Xcode. These plain text files are friendlier to source control systems. They can be modified with any editor. Each file has key-value assignments. The syntax is: BUILD_SETTING_NAME = value.
The .xcconfig extension is for Apple Xcode configuration settings files. Apple defined this format standard. These files may be used by Mac OS programs. The .xcconfig file format belongs to the Settings Files category with 1305 others. Xcode is the recommended software for managing these files.
You can include settings from other configuration files. Add an #include statement like: #include “MyOtherConfigFile.xcconfig”. If Xcode can’t find an included file, it generates warnings. You can suppress warnings by adding “?” after #include.
.xcconfig files store parameters for configuring Xcode project builds. They can be referenced by multiple projects to share build settings. We know file formats and extensions. We provide openers to download.
