推荐答案

如果确定确保数组中包含的字符串始终以£开头,您可以这样做:

If you're sure that the strings contained in your array always start with a £, you could do this:

let sum = array.compactMap { Double($0.replacingOccurrences(of: "£", with: "")) }
               .reduce(0.0, { $0 + $1 })

示例:

let array = ["£179.95", "£199.95", "£89.95"]
let sum = array.compactMap { Double($0.replacingOccurrences(of: "£", with: "")) }
               .reduce(0.0, { $0 + $1 })
print(sum) // 469.84999999999997
