I have a list of IDs. Also I have an object that has arrays of datas like the below structure.

[
    foods(
        foodId: 345, 
        category: 10, 
        tools: [10], 
        name: "food name 1"
    ),

    foods(
        foodId: 191, 
        category: 4, 
        tools: [2], 
        name: "food name 2"
    ), 
]

In my list I have list [345, 191]

I want to have a mechanism to access the information of the object when I provide a foodId.

I made it work with one inner and one outer loop. But I was wondering if there is an easier way to do it:

ForEach(foodDetails, id: \.self){ item in
    ForEach(self.foods.datas){ ex in
        if(ex.foodId == item){
            Text(ex.name)
    }
}

Any idea how to make it work?

Thanks in advance

you can do simply by getting first element where id match

let result = foodDetails.first(where: {$0.foodId == id})

 if let food = result {
        print(food.name ?? "") //if name is optional
        print(food.foodId)
        print(food.category)
    }

result you got is that foods? optional struct which have this id
