App api request gives timeout and not internet connection

Upon successful facial authentication, the application proceeds to make requests to our APIs.

What Apple API are you using to make these requests?

We are using NSMutableURLRequest

With NSURLSession, right?

NSURLSession supports standard and background sessions. If your use a standard session the work is done by your process. If your app moves to the background and then gets suspended, you’ll encounter weird problems. You have a bunch of options for dealing with that:

• Cancel your requests when you move to the background.

• Use a UIApplication background task to prevent your app being suspended while a request is in flight. See UIApplication Background Task Notes for more info on that API.

• Switch to a background session.

The best option depends on the nature of your requests. For interactive work, like what you’re describing, I usually recommend one of the first two options. Background sessions work best with a small number of a large requests.

We are using NSURLSessionDataTask.

Data tasks can be used in a background session, but with significant limitations [1]. Most folks using data task are using a standard session.

But why it was working fine in iOS 16.3

It’s hard to say without an in-depth analysis, and I’m not sure that’s warranted. The rules for standard sessions have always been that you must either:

• Ensure that your app doesn’t get suspended while a request is in flight, or

• Deal with the request failing with a wacky error if your app does get suspended.

[1] Unlike upload and upload tasks, data tasks in a background session won’t keep running when your app is suspended, so they behave much like data tasks in a standard session.
