Swift4基本的错误汇总

一.示例代码如下：

let tempMinArr = minDyArr.sorted { (m1, m2) -> Bool in
     return Int(m1)! < Int(m2)!
}

问题：需要排序的数组中如果装入的有像"90.00"这类的浮点型字符串,那么会导致崩溃。

问题处理：

let tempMinArr = minDyArr.sorted { (m1, m2) -> Bool in
    return Double(m1)! < Double(m2)!
}

or

let tempMinArr = minDlArr.sorted { (m1, m2) -> Bool in
   return (m1 as NSString).intValue < (m2 as NSString).intValue
}
