I’m developing an iOS application in Swift that performs API calls using URLSession.shared. The requests work correctly when the app is in the foreground. However, when the app transitions to the background (for example, when the user switches to another app), the ongoing API calls are either paused or do not complete as expected.
What I’ve tried:
Using URLSession.shared.dataTask(with:) to initiate the API requests
Observing application lifecycle events like applicationDidEnterBackground, but haven’t found a reliable solution to allow requests to complete when backgrounded
Goal:
I want certain API requests to continue running or be allowed to complete even if the app enters the background. (The poll will finish within 2 minutes)
Question:
What is the correct approach to allow API calls to continue running or complete when the app moves to the background?
Should I be using a background URLSessionConfiguration instead of URLSession.shared?
If so, how should it be properly configured and used in this scenario?
