Open SwiftUI App from other application, Microsoft Teams, Messenger, WhatsApp, etc - ios

Question

I am developing an SwiftUI App that app involves with creating notes like an usual to-do list app. The exception is that the note must be able to be shared to another users via Microsoft Teams, Messengers and WhatsApp.
Thus, I tend to implement some sort of functionalities to send another user one URL link. Every time the users click on the link from third-party app (WhatsApp, Teams, FB), the link will prompt and navigate users to the app that I developed and installed on their machine. Based on the URL my app will perform specific actions.
How I can do that. My current attempt is to define a customer URL for the SwiftUI app.
Thanks for reading this question, cheers.

Answer 1

You are looking for Custom URL Scheme and Universal Links
From documentation:
Custom URL schemes provide a way to reference resources inside your app. Users tapping a custom URL in an email, for example, launch your app in a specified context. Other apps can also trigger your app to launch with specific context data; for example, a photo library app might display a specified image.
let url = URL(string: "myphotoapp:Vacation?index=1")
UIApplication.shared.open(url!) { (result) in
if result {
// The URL was delivered successfully!
}
}
