在rxDataSource库下怎么用？

struct NormalSecModel{

var title: String
var isMore: Bool = true
var iconUrl: String
var items: [Item]

}
extension NormalSecModel: SectionModelType {
typealias Item = NormalCellModel

init(original: NormalSecModel, items: [Item]) {
self = original
self.items = items
}
}

extension NormalSecModel: HandyJSON {
init() {

}
}

此时就会报错Return from initializer without initializing all stored properties
有案例吗

Start with the NormalSecModel declaration and its HandyJSON initializer shown in the issue, then review how the model is intended to work with rxDataSource. Confirm what initialization example should be documented and that the example no longer produces the reported stored-property initialization error.
