How can I get the filename without the extension?
In Swift, you can get the file name without the extension by using the lastPathComponent property of the URL class and then removing the extension using the deletingPathExtension method. Here is an example:
let fileURL = URL(fileURLWithPath: "/path/to/file.txt")
let fileNameWithoutExtension = fileURL.deletingPathExtension().lastPathComponent
print(fileNameWithoutExtension) // Output: "file"
You can also achieve the same result using the NSString API, here's an example:
let filePath = "/path/to/file.txt"
let fileNameWithoutExtension = (filePath as NSString).deletingPathExtension
print(fileNameWithoutExtension) // Output: "file"
