How do I get the font name from an otf or ttf file?

Question

I have used a custom font in my previous app.

The file name was \"ProximaNova-Regular.otf\" and to load the font I just used...

[UIFont fontWithName:

If you want to find the font name for a given font file programmatically:

import Foundation

func loadFontName(for file: URL) throws -> String {
    let data = try Data(contentsOf: file)

    guard let provider = CGDataProvider(data: data as CFData) else {
        throw Error("Could not create data provider")
    }

    guard let font = CGFont(provider) else {
        throw Error("Could not load font")
    }

    guard let name = font.postScriptName else {
        throw Error("Could not get font name from font file")
    }

    return name as String
}

Replace with your own throwable Error objects as required.
