swift 数组操作

数组：

*懒加载

    lazy var homeListArray: [HomeIndexDataModel] = {
        let tempArr = [HomeIndexDataModel]()
        return tempArr
    }()

*数组加载元素
homeListArray.append(item)
*数组遍历

for (index, item) in homeListArray.enumerated() {
                    if item.marketId == model?.MARKET?.marketId {
                        homeListArray.remove(at: index)
                        homeListArray.insert((model?.MARKET)!, at: index)
                        if homeListArray.count > 0 {homeBottomListTableView.reloadData()}
                    }
                }
