File Extensions

During recent development, I encountered a rather basic problem—similar to a cloud drive app needing to distinguish various file types, find the corresponding file icon, and display it. As an iOS developer with a geek spirit, I wanted to find a collection of file extension names without having to define my own enum values. This reminded me of researching AirDrop around 2015 when developing Baidu Netdisk, where Apple required providing a Uniform Type Identifier (UTI) for sharing files to other phones. So I looked up the documentation and recorded the following file type list.

Apple’s CoreServices.framework contains a UTCoreTypes.h header file that records all file types.

Below is the code with all comments removed. Of course, these are limited to the types Apple can natively recognize. Less commonly used file types or custom extension file types are not covered here—if needed, you can use a wildcard type or handle them separately.
