Question

我有一个字符串： “我有67 + 89.06美元。”

现在我想进行计算并将字符串更新为： “我有156.06美元。”

使用Swift如何执行此任务？

原始字符串中的数字可以是任何值，而不仅仅是我上面写的内容。

我建议您阅读developer.apple.com上的Apple文档

 "I have 67+89.06 Dollars."
   // In order to get a Float value both operands need to be of type Float. 
     let valueCalculate = "I have \(Float(67) +   Float((89.06))) Dollars"
print(valueCalculate)

// Convert String to Int
 var stringNumber = "123456"
  var convertToInt = Int(stringNumber)

 // Convert Float value to Int
   var stringNumber = "123456"
    var convertToInt = Int(stringNumber)

  //convert value of type Float written as a String to Float
     var stringWithFloatValue = "123.250"
     var stringtoFloatValue = Float(stringWithFloatValue)

    //convert Float value to Int
    if stringtoFloatValue != nil {
       let floatToInt = Int(stringtoFloatValue!)
 }

如何转换String并在Swift中执行计算？
