从联系人处获取号码但无法清除号码

Question

我从联系人列表中获取数字，但它给了我“+593 99 999 9999”我已经在做以下

item = item.replacingOccurrences(of: " ", with: "")
item = item.replacingOccurrences(of: "-", with: "")
item = item.replacingOccurrences(of: "+", with: "")
item = item.replacingOccurrences(of: "\\U202a", with: "")
item = item.replacingOccurrences(of: "\\U202c", with: "")
item = item.replacingOccurrences(of: "\\U00a0", with: "")

我的最终结果是“593 99 999 9999”它没有用我已经拥有的代码替换\ U00a0。有没有人有更好的方法来做到这一点？
