Value types in programming are data types whose instances are stored directly in the variable's memory. When assigning or passing such types, a copy of the value is created, not a reference to the original object.

Examples of value types in Swift (commonly used in iOS):

• Int, Double, Bool — basic numeric and logical types.
• Struct (structures) — user-defined types that are copied upon assignment.
• Enum (enumerations).

Unlike reference types, such as classes (class), where the variable contains a reference to an object in memory, value types provide safety against unintentional modifications through copies.

Example:

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

var p1 = Point(x: 10, y: 20)
var p2 = p1  // a copy is created
p2.x = 30
print(p1.x) // 10 — p1 has not changed

This is important for code predictability and safety, especially in multi-threaded applications.
