RxSwift RxDataSources crash while refreshing data

// In the drop-down refresh, the queried result is directly replaced with the original data

headerRefreshData.drive(onNext: { (observable) in

let data = (observable.data! .records)!

var list = [MessageSection]()

for item in data {

let num = “\(Int(arc4random()))”

let model = MessageSection(header: num, data: [item])

list.append(model)

}

self.tableData.accept(list)

}).disposed(by: dependency.disposeBag)

Solution: RxTableViewSectionedAnimatedDataSource replace RxTableViewSectionedReloadDataSource, the reason is unknown, free again to study
