当两个变量或者常量 相加时 类型不一样 ，就会出此错 例如
var stringOne = " swift "
var numberOne = 94
错误：var stringNum = stringOne + numberOne
正确的做法: var stringNum = stringOne + String(numberOne)
var integerNum = 10
var doubleNum = 10.0
错误： var addNum = integerNum + doubleNum
正确的做法: var addNum = Float(integerNum) + Float(doubleNum)
var stringOne = " swift "
var numberOne = 94
错误：var stringNum = stringOne + numberOne
正确的做法: var stringNum = stringOne + String(numberOne)
var integerNum = 10
var doubleNum = 10.0
错误： var addNum = integerNum + doubleNum
正确的做法: var addNum = Float(integerNum) + Float(doubleNum)
