可以将属性名称传递给 Swift 中的函数吗

我有一个 struct ，其中包含一组引用不同类型统计信息的属性.示例对象为:

class Stats {
    stats: [Stat]
}
struct Stat {
    id: UUID
    countA: Int
    countB: Int
    countC: Int
    totalAAttempts: Int
    totalBAttempts: Int
    totalCAttempts: Int
    ...
}

我正在用类中的一系列函数显示百分比.

class Stats {
    stats: [Stat]
    var countAPerc: Double {
        let totalA = stats.reduce(0) { total, stat in
            total + stat.countA
        }
        let totalAttemps = s.reduce(0) { total, stat in
            total + stat.totalAAttempts
        }
        return Double(totalA) / Double(totalAttempts)
    }
    var: countAPercDisplay: String {
        String(format: "%.1f", countAPerc * 100) + "%"
    }
    var countBPerc: Double {
        let totalB = stats.reduce(0) { total, stat in
            total + stat.countB
        }
        let totalAttemps = s.reduce(0) { total, stat in
            total + stat.totalBAttempts
        }
        return Double(totalB) / Double(totalAttempts)
    }
    var: countBPercDisplay: String {
        String(format: "%.1f", countBPerc * 100) + "%"
    }
    ...
}

是否可以将属性的名称指定为函数中的参数，以防止相同的代码被反复重写？类似于:

func summarizeProperty(_ countProperty: PROPERTYNAME1, _ totalProperty: PROPERTYNAME2) -> Double {
    let totalCount = stats.reduce(0) { total, stat in
        total + stat.PROPERTYNAME1
    }
    let totalAttemps = s.reduce(0) { total, stat in
        total + stat.PROPERTYNAME2
    }
    return Double(totalCount) / Double(totalAttempts)
}

func summarizedProperty(_ countProperty: PROPERTYNAME1, _ totalProperty: PROPERTYNAME2) -> String {
    let summarized = summarizeProperty(PROPERTYNAME1, PROPERTYNAME2)
    return String(format: "%.1f", summarized * 100) + "%"
}

然后叫它...

Text(summarizedProperty(countA, totalAAttempts))
