I am getting a folder url from user and then looking to find any mp3 files in that folder, the question itself in title and me just looking to use UTType in process.
As you can see I took all steps in codes just need last step in isMP3 function to finish the puzzle. So how can I use a path or URL and fining out the UTType of it and using it for comparing.
Also in my approach Xcode gave an error and says:
Cannot find ‘UTType’ in scope
Not sure why I have this error, normally it should Not be case, because it is type defined by Apple.
struct ContentView: View {
@State private var fileImporterIsPresented: Bool = false
var body: some View {
Button("Select your Folder") { fileImporterIsPresented = true }
.fileImporter(isPresented: $fileImporterIsPresented, allowedContentTypes: [.folder], allowsMultipleSelection: false, onCompletion: { result in
switch result {
case .success(let urls):
if let unwrappedURL: URL = urls.first {
if let contents = try? FileManager.default.contentsOfDirectory(atPath: unwrappedURL.path) {
contents.forEach { item in
if isMP3(path: unwrappedURL.path + "/" + item) {
print(item)
}
}
}
}
case .failure(let error):
print("Error selecting file \(error.localizedDescription)")
}
})
}
}
func isMP3(path: String) -> Bool {
// trying use UTType here
if URL(fileURLWithPath: path).??? == UTType.mp3 {
return true
}
else {
return false
}
}
>Solution :
To use UTType you have to import explicit package
import UniformTypeIdentifiers
it can be something like
func isMP3(path: String) -> Bool {
if let type = UTType(filenameExtension: URL(fileURLWithPath: path).pathExtension), type == UTType.mp3 {
return true
}
else {
return false
}
}
