Amplify Gen 2 Documentation for Custom Subscription Client-Side Swift/iOS

[harikrishna-22]

Describe the content issue:
Hi, I asked this question in office hours where there isn't documentation provided for how to subscribe to custom real-time scubscriptions in the client side for swift. It seems to reuse the same react documentation. Please help me understand after creating those backend files, how to call the custom subscription on my ios app using swift.
