如何在Swift中编写将枚举与枚举大小写进行比较的函数

enum MyEnum: String {
    case apple
    case banana
    case orange
}

func compareEnumCaseInsensitive(enum1: MyEnum, enum2: MyEnum) -> ComparisonResult {
    return enum1.rawValue.caseInsensitiveCompare(enum2.rawValue)
}

let result = compareEnumCaseInsensitive(enum1: .apple, enum2: .Banana)
if result == .orderedSame {
    print("枚举值相同")
} else if result == .orderedAscending {
    print("enum1的大小写小于enum2")
} else if result == .orderedDescending {
    print("enum1的大小写大于enum2")
}
