Userdefault.standardを用いた際のエラー
swiftに関する質問です．アーティスト名とそのアーティストの曲とそのキーを入力し，Userdefault.standardに保存することでリストを作成するアプリを作成しています．しかし，ビルドは成功するもののデータを入力する際に，決定ボタンを押すと Thread 1: signal SIGABRT と表示されアプリが止まってしまいます．エラーコードから推測するとUserdefault.standardに空のartistクラスを保存しようとしていることがいけないのかも知れません． また，入力するデータを["","",""] にすると決定ボタンを押しても止まることはありませんでした．なのでif分以下の，データを格納する部分の分岐でエラーが発生していると考えています． 解決方法がわからないためみなさんに質問させていただきたいです．以下にコードとエラーを載せます．
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view.
let defaults = UserDefaults.standard
//クラスの中にアーティスト情報を格納する
// for i in 0..<sectionTitle.count {
// let band = artist(artist: sectionTitle[i], song: "", key: "")
// band.songList = (tableData[i])
// allData.append(band)
// }
// defaults.set(allData, forKey: "allData")
}
override func viewWillAppear(_ animated: Bool) {
let defaults = UserDefaults.standard
var names:[String] = []
var songs:[String] = []
var artistIndex = 0
var songIndex = 0
for i in 0..<allData.count {
names.append(allData[i].artistName)
}
if names.firstIndex(of: newSong[0]) != nil{
artistIndex = names.firstIndex(of: newSong[0])!
for i in 0..<allData[artistIndex].songList.count {
songs.append(allData[artistIndex].songList[i][0])
}
if songs.firstIndex(of: newSong[1]) != nil {
songIndex = songs.firstIndex(of: newSong[1])!
}
}
if newSong == ["","",""] {
//何もしない
} else if !names.contains(newSong[0]) {
//アーティストのクラスを作成し追加
var tmpData = defaults.array(forKey: "allData") as! [artist]
let band = artist(artist: newSong[0], song: newSong[1], key: newSong[2])
tmpData.append(band)
defaults.set(tmpData, forKey: "allData")
} else if !songs.contains(newSong[1]) {
//既存のアーティストに曲を追加
let index = names.firstIndex(of: newSong[0])!
var tmpData = defaults.array(forKey: "allData") as! [artist]
tmpData[index].songList.append(Array(newSong[1...2]))
defaults.set(tmpData, forKey: "allData")
} else {
//既存のアーティストのきょくのキーを変更
var tmpData = defaults.array(forKey: "allData") as! [artist]
tmpData[artistIndex].songList[songIndex][1] = newSong[2]
defaults.set(tmpData, forKey: "allData")
}
// sectionTitle = defaults.stringArray(forKey: "sectionTitle")!
// tableData = defaults.array(forKey: "tableData") as! [[[String]]]
//並べ替え
allData.sort(by: {String($0.artistName) < String($1.artistName)})
for i in 0..<allData.count {
allData[i].songList.sort(by: {String($0[0]) < String($1[0])})
print(allData[i].artistName, allData[i].songList)
}
let MyTableView: UITableView!
MyTableView = UITableView(frame: view.frame, style: .grouped)
MyTableView.delegate = self
MyTableView.dataSource = self
view.addSubview(MyTableView)
}
}
以下がエラー文です．
