如何从字符数组中删除这个“”？

如何解决如何从字符数组中删除这个“”？

这作为字符串返回给我：

result: vier­hundert­sieben­und­achtzig

我将字符串投射到数组中。

self.randomNumberText = Array(self.numberConfig.numberString)
print("\(self.randomNumberText)")
["v","i","e","r","­","h","u","n","d","t","s","b","a","c","z","g"]

单词之间有空心引号("")。如何删除这些双引号（“”）？ 我在数组中转换字符串的原因：我检查从 TextField 输入的每个字母是否拼写正确。但是，由于中间有“”这个符号，我无法检查它是否拼写正确。

号码配置

class NumberConfig: ObservableObject {
    
    @Published var numberString: String = "-"

    @Published var randomNumber: Int = 0 {
        didSet {
            self.numberString = self.numberToText(number: randomNumber)
        }
    }
    
    func numberToText(number: Int) -> String {
        let formatter = NumberFormatter()
        formatter.locale = Locale(identifier: "de")
        formatter.numberStyle = .spellOut
        formatter.minimumIntegerDigits = 2
        let result = formatter.string(for: number) ?? "-"
        print("result: \(result)")
        return result
    }
}

                            .frame(width: 10,height: 10)
                            .padding(5)
                    }
                    .padding(.horizontal)

    }

解决方法

过滤 Character 数组有点棘手，因为空字符串实际上不是字符。

不过有一种方法：过滤所有 ASCII 字符

self.randomNumberText = Array(self.numberConfig.numberString).filter{$0.isASCII }

或过滤所有letters

self.randomNumberText = Array(self.numberConfig.numberString).filter{$0.isLetter }
