How to delete specific item from array in swift?

I am using an array that is filled with structs:

struct CartModel: Codable {
    var product_id: Int
    var line_subtotal: Float
    var line_total: Float
    var line_tax: Float
    var line_subtotal_tax: Float
    var key: String
    var quantity: Int
}

    static var fullCart = [CartModel]()

Now I am trying to delete one of those from the array. I tried to use fullCart.index(of:), but it is giving me the following error:

Argument labels '(of:, _:)' do not match any available overloads

I was hoping to use fullCart.remove(at:), but because of not being able to find the right index I am not sure how to remove the right item.

You also can find index by index(where:) and then delete item from array:

if let index = fullCart.index(where: { $0.product_id == otherCartModel.product_id }) {
    fullCart.remove(at: index)
}

Or conform to Equatable protocol and use index(of:):

struct CartModel: Codable, Equatable {
    ...

    static func == (lhs: Self, rhs: Self) -> Bool {
        return lhs.product_id == rhs.product_id
    }
}

if let index = fullCart.index(of: otherCartModel) {
    fullCart.remove(at: index)
}
