Swift check MIME type based on magic bytes. Swime detects MIME type of a Data, ported from sindresorhus/file-type
import PackageDescription
let package = Package(
name: "MyApp",
dependencies: [
.Package(url: "https://github.com/sendyhalim/Swime", majorVersion: 3)
]
)Inspect mime type
import Swime
let path = "/path/to/some-file.jpg"
let url = URL(fileURLWithPath: path, isDirectory: false)
let data = try! Data(contentsOf: url)
let mimeType = Swime.mimeType(data: data)
mimeType?.type == .jpg // true
mimeType! // MimeType(mime: "image/jpeg", ext: "jpg", type: .jpg)
switch mimeType?.type {
case .jpg?:
....
case .png?:
....
case .wmv?:
....
case ...
}Pass bytes to it
import Swime
let bytes: [UInt8] = [255, 216, 255]
let mimeType = Swime.mimeType(bytes: bytes)
mimeType! // MimeType(mime: "image/jpeg", ext: "jpg", type: .jpg)Here are the list of available MimeTypeExtension.
