A generic error I use in Swift, typically for cases that are not intended to be dealt with in a manner other than being logged

GenericError.swift

struct GenericError: Error, CustomStringConvertible, CustomDebugStringConvertible, Equatable, Codable {
    let description: String
    let file: String
    let function: String
    let line: Int
    
    init(message m: String, file f: String = #file, function n: String = #function, line l: Int = #line) {
        description = m; file = f; function = n; line = l
    }
    
    var debugDescription: String {
        /* this looks like: file.swift:1 function(parameter:) "description" */
        return "\(file):\(line) \(function) \"\(description)\""
    }
}
