私はこのライブラリをSwiftフォームに使用しています：https://github.com/ortuman/SwiftFormsこれはEurekaに非常に似ています。アサーションに失敗しました：self.formプロパティを割り当てる必要があります
私は2つのピッカーを持って、私のフォームで：
は、ここで私が何をしようとしています何の説明です。 Picker1は通常のピッカーですが、Picker2はPicker1の値に依存します。したがって、ユーザーがPicker1の値を変更したとき。 Picker2のオプションも変更する必要があります。私は私の2つのピッカーの値の変化を見るためにreloadData()を使用
func change_data(){
row4.configuration[FormRowDescriptor.Configuration.Options] = ["hello", "from", "the"]
row4.value = "hello"
self.tableView.reloadData()
}
：これを行うには、ここに私の機能です。しかし、残念ながら、私はエラーを取得します：assertion failed: self.form property MUST be assigned!
トップバーのボタンの動作にそのコードを入れてみました。
func submit(_: UIBarButtonItem!) {
//let message = self.form.formValues().description
//let alert: UIAlertView = UIAlertView(title: "Form output", message: message, delegate: nil, cancelButtonTitle: "OK")
//alert.show()
row4.configuration[FormRowDescriptor.Configuration.Options] = ["hello", "from", "the"]
row4.value = "hello"
self.tableView.reloadData()
}
しかし、ボタンのクリックではなく私の機能の中でreloadData()に電話する必要があります。
ここに私のFormViewControllerののviewDidLoadだ：私はいくつかのピッカーを持って、そして最後のピッカーが2日から選ばれた項目に依存します 
：私が達成しようとしています何
public override func viewDidLoad() {
super.viewDidLoad()
assert(form != nil, "self.form property MUST be assigned!")
navigationItem.title = form.title
}

どういう意味ですか？ –

と同じです。人々が答えるためには、コードを最小限の例に簡素化する必要があります。あまりにも多くのコードが問題に重要ではなく、何とか私はいくつかの重要な部分が欠けていると感じます。 – Sulthan
