CodePudding user response：

Yes the review_point is of type String and not Float, as suggested by @burnsi

After getting the string value you can always parse it to Float

CodePudding user response：

Since the main issue here seems to be how to get the correct data to display here is solution that focus on that but ignores any UI related stuff since I consider it off-topic.

I did some changes to the structure but nothing major, changed from class to struct, removed some optionals that didn't make sense and changed from var to let but feel free to change it back since it isn't really important to the answer.

public struct BuyserReviewResult {
    public let reviewcat : [Reviewcat]
    public let reviewDet : ReviewDet?
}

public struct Reviewcat {
    public let review_name : String
    public let id : Int
}

public struct ReviewDet {
    public let review_details : [Review_details]
}

public struct Review_details {
    public let review_cat_id : Int
    public let review_point : Float
}

Now you can simply get each category name and the points for that category by doing

for category in result.reviewcat {
    let points = result.reviewDet?.review_details
        .first(where: { $0.review_cat_id == category.id })?.review_point ?? 0.0
    print(category.review_name, points)
}

Note that also ignored the top level type here since it is no longer needed once you have parsed the data.
