PCH can be used to store shared information, such as the width and height of a device's screen. Version number and so on common informationThe old version of Xcode automatically creates a PCH file for us, and the new version is not created automatically, if you need to create it yourself manuallyConstants can be defined inside after creation is completeHere is an example of screen sizeAs follows------------

Hello world_prefix.pch: the extension. PCH indicates "precompiled header". This is a list of header files from the external framework used by your project. Xcode will compile these headers to files, which will reduce the time for you to compile the project when you select build or build and go. Usually, the header file is automatically included. PCH: the system will include this file before compiling every
