Import another file in Swift

In Swift, you can import another file by using the import statement followed by the name of the file or module you want to import. Here's an example:

Suppose you have two files in your project: MyModule.swift and MyProgram.swift. If you want to import MyModule.swift into MyProgram.swift, you would use the following code at the top of MyProgram.swift:

import MyModule

This assumes that MyModule.swift is in the same folder as MyProgram.swift and that MyModule.swift declares a module called MyModule.

If MyModule.swift is in a different folder or location, you would need to specify the full path to the file in the import statement:

import /path/to/MyModule

Alternatively, you can import specific parts of a module by using the import statement followed by a dot . and the name of the specific part you want to import. For example:

import UIKit.UIView

This imports only the UIView class from the UIKit module.

Keep in mind that some modules may require additional setup or configuration in order to be imported successfully. Also, importing different modules or parts of modules can affect the efficiency and size of your application, so it's important to import only what you need.
