What are the advantages and disadvantages of this structure?

It is difficult to give an exact answer without a specific description of the structure, but general advantages and disadvantages of data structures in iOS (for example, struct in Swift) can be considered.

Advantages of structures (struct) in Swift:

• Value type: copied upon assignment, preventing unexpected side effects.
• Performance: often faster than classes, as they are stored on the stack.
• Safety: immutability (if declared as let) helps avoid errors.
• Simplicity: suitable for small, simple data models.

Disadvantages:

• Lack of inheritance: cannot create hierarchies like with classes.
• Copying large structures: can be memory-intensive if the structure is large.
• Reference semantics limitations: sometimes a reference to an object is needed, not a copy.

Example of a structure in Swift:

struct Point {
    var x: Double
    var y: Double
}

var p1 = Point(x: 0, y: 0)
var p2 = p1 // creates a copy
p2.x = 10
print(p1.x) // 0
print(p2.x) // 10
