SwiftObjC

Find the Details explanation here in my Medium Article :

In this project I have used shown both use cases

Obj C in Swift and Swift in Obj C

#Code Explanation:

 import UIKit
  class ViewController: UIViewController {

   override func viewDidLoad() {
    super.viewDidLoad()
    // Do any additional setup after loading the view.
    
   let testObjC : TestObjC = TestObjC()
    testObjC.testProperty = "Hello ObjC"
    print(testObjC.testProperty!)
    testObjC.testMethod()  
    testObjC.testSwift()
 }
}

The above class is a Swift Class File creating an instance of an ObjC class TestObjC and accessing its properties and methods

In line testObjC.testSwift() when we jump to Obj C file we use Swift Class TestSwift and access its methods.

- (void) testSwift {
TestSwift* swiftObj = [[TestSwift alloc] init];
[swiftObj testsFunction:@"Hello Swift"];
}

Sorry !!! I am just lazy to create two different project , so I showed both the use case in one project . Check the medium article above for more detailed explanation and insight.
