Issue with MusicXML file

[Frank Nichols]

I am new to XML decoding and have a issue decoding this part of a musicXML file with your decoder.

Issues:

(Item 1 I figured out what I was doing wrong.)
// 1. Attributes on measure element (number="4" width="267.83") are missing - or I don't understand
// how to setup the structure to return them - using the XMLParser the attributes show up.

2. <rest/> doesn't get detected/decoded - or I don't know how to differentiate between this and a missing "rest" element since both show in my structure as nil.

(grr - item 3 was a typo on me.)
//3. barline element bar-style is not decoded and/or returns nil and the barline attribute (direction) is //not decoded or I do not know how to setup my structure.

Here is a print of that part of the score struct:

xmlTest.Note(rest: nil, pitch: nil, duration: Optional(1), voice: Optional(1), type: Optional("quarter"), stem: nil)]), barlne: nil)

(fragment of musicXML file)

         <measure number="4" width="267.83">
           <note>
                <rest/>
                <duration>1</duration>
                <voice>1</voice>
                <type>quarter</type>
            </note>
            <barline location="right">
                <bar-style>light-heavy</bar-style>
                <repeat direction="backward"/>
            </barline>
        </measure>

...

(structs to receive decoded data)

struct Measure: Codable  {
    var number: Int?
    var width: Float?
    var attributes: Attributes?
    var note: [Note]?
    var barline: Barline?
}

struct Attributes: Codable  {
    var divisions: Int?
    var key: Key?
    var time: Time?
    var clef: Clef?
}

struct Note: Codable  {
    var rest: String?
    var pitch: Pitch?
    var duration: Int?
    var voice: Int?
    var type: String?
    var stem: String?
}

struct Barline: Codable  {
    var barStyle: String?
    var repeatType: String?
    
    enum CodingKeys: String, CodingKey {
        case barStyle = "bar-style"
        case repeatType = "repeat"
    }
}

And here is the code fragment for the decoding:

            let decoder = XMLDecoder()
            
            let formatter: DateFormatter = {
                let formatter = DateFormatter()
                formatter.dateFormat = "yyyy-MM-dd"
                return formatter
            }()
            
            decoder.dateDecodingStrategy = .formatted(formatter)
            
            do {
                let score = try decoder.decode(Score.self, from: data)
                print("Score: \(score)")
            } catch {
                print(error)
            }
