Here, we will implement hybrid inheritance by combining two types of inheritances. In our case, we will combine hierarchical and multilevel inheritances.
The source code to implement hybrid inheritance is given below. The given program is compiled and executed successfully.
// Swift program to implement hybrid inheritance
import Swift
class A {
var numA: Int = 0
func setA(n: Int) {
numA = n
}
func printA() {
print("numA: ", numA)
}
}
class B : A {
var numB: Int = 0
func setB(n: Int) {
numB = n
}
func printB() {
print("numB: ", numB)
}
}
class C : B {
var numC: Int = 0
func setC(n: Int) {
numC = n
}
func printC() {
print("numC: ", numC)
}
}
class D : A {
var numD: Int = 0
func setD(n: Int) {
numD = n
}
func printD() {
print("numD: ", numD)
}
}
var obj1 = C()
var obj2 = D()
obj1.setA(n:10)
obj1.setB(n:20)
obj1.setC(n:30)
obj1.printA()
obj1.printB()
obj1.printC()
obj2.setA(n:40)
obj2.setD(n:50)
obj2.printA()
obj2.printD()
Output:
numA: 10
numB: 20
numC: 30
numA: 40
numD: 50

Explanation:
In the above program, we imported a package Swift to use the print() function using the below statement,
import Swift
Here, we created five classes A, B, C, D, E. And, we inherited class A into B and D classes. The class B is inherited into C. Then we created the objects of the C and D classes and then set and print values on the console screen.
