ContentType

public class ContentType

The ContentType class provides functions to determine the MIME content type for a given file extension. The user can pass in a complete file name e.g. “foo.png” or just the file extension e.g. “png”, or they can pass in both a MIME content type and a file extension and query whether they match.

Usage Example:

In this example, a ContentType instance is initialised called contentType. This instance is then used to obtain the MIME content type of the file “foo.png”, which is identified as “image/png”.

let contentType = ContentType.sharedInstance
let result = contentType.getContentType(forFileName: "foo.png")
print(String(describing: result))
// Prints Optional("image/png")

`

                sharedInstance
                `

Shared singleton instance.

Declaration

Swift

public static let sharedInstance: ContentType

`

                getContentType(forExtension:)
                `

Get the content type for the given file extension.

Usage Example:

let contentType = ContentType.sharedInstance
let result = contentType.getContentType(forExtension: "js")

//Prints Optional("application/javascript")

`

                getContentType(forFileName:)
                `
