How to remove an element from array of object on swift based on id? [closed]

Question

I have a array of objects such as.

var arrStudents = [S1,S2,S3,S4,S5]

Here s1 is object of student class

class Student {

    var id:Int!
    var name:String!
    var address:String?
    var phone:Int!
}

Now I want to delete a record from array by the the student id. please tell me how can I do this.

Answer 1

loop through all the indexes of the array and check if the id you want to delete matches, if yes it will filter out and you can remove that index :-)

let idToDelete = 10
if let index = arrStudents.index(where: {$0.id == idToDelete}) {
    array.remove(at: index)
}

if you want to remove multiple value in single iteration you should start the loop from last index to first index, so it will not crash (out of bound error )

var idsToDelete = [10, 20]
for id in idsToDelete {
        for (i,str) in arrStudents.enumerated().reversed()
        {
            if str.id == id
            {
                arrStudents.remove(at: i)
            }
        }
    }
