Loading lots of contacts (20k) on ios 18 produce timeouts

[dtalbot-goto]

We've got an issue in our app on iOS 18 where there are huge amount of local contacts (20k) and the getAll does not resolve. We had to add a timeout of 60 seconds to make the loading stop. I also tested on iOS 17.6.1 and the contacts load fine within 60 seconds.

Something must have changed for iOS 18 on that matter. I tested 18.0.1 and 18.1.1 - same results.

I also reproduce the above issue on iOS 18.1.1 with an iPhone 14. It could be good to note that the phone became pretty hot, and I had to restart it at some point!
