How to create UIDocumentInteractionController in swift

Introduction to UIDocumentInteractionController Swift:

In this post we will learn how to create UIDocumentInteractionController in Swift language. We will create an example app to learn how to use UIDocumentInteractionController in swift.

Change project language to swift

Press Next and then select location for your project where you want to save the project, press create to create your project.

Open ViewController.swift file. Now we will create variable for UIDocumentInteractionController.


Open your Main.storyBoard and drag UIButton to it. It’s time to create an IBAction for our button so that we can open UIDocumentInteractionController on pressing it.


Connect your button dragged in last step on Main.storyBoard with your IBAction to UIButtonTouchUpInside event.

Open ViewController.swift file and now we will write code to present UIDocumentInteractionController to the user.


In above code, first we get file url which we want to share using UIDocumentInteractionController (in our case its an image place locally in our project). After we get file path we created our UIDocumentInteractionController by using init method and pass the file url to it. Lastly, we user presentOptionsMenuFromRect method to show UIDocumentInteractionController to the user.
PresentOptionMenuFromRect take three parameters
1) frame: from where we want to the menu
