I'm trying to resolve NSNetService address in the Siri extension, but nothing happens - resolveWithTimeout is called, but after a while Siri just times out. Same code works in the main app..

To see what happens I have set timeout to 1 sec - and it still doesn't time out, it just does nothing.

OK, after some time - it seems that it does work, but resolving takes a LOT of time (~2 min) while in app is almost instant.

How are you scheduling the

NSNetService

delegate callback? I suspect what’s happening here is that the service is scheduled on a run loop that’s not run very often, and hence the huge delay.

The other possibility is that your app extension is being suspended; you can rule out that possibility by using

-[NSProcessInfo performExpiringActivityWithReason:usingBlock:]

to temporarily prevent suspension.

Oh, and finally, why are you resolving this service? I generally try to avoid doing that, but instead use a connect-to-service API where possible.
