Just going through the tutorial, got to the iOS part. Am running OS X 10.10.5 with dev tools. Was already running Meteor on port 3000 so did this, got:
$ meteor run ios --port 3001
[[[[[ ~/projects/simple-todos ]]]]]
=> Started proxy.
Unexpected mongo exit code 100. Restarting.
Unexpected mongo exit code 100. Restarting.
Unexpected mongo exit code 100. Restarting.
Can't start Mongo server.
MongoDB had an unspecified uncaught exception.
This can be caused by MongoDB being unable to write to a local database.
Check that you have permissions to write to .meteor/local. MongoDB does
not support filesystems like NFS that do not allow file locking.
I read up about the error, tried the fixes that aren’t a complete and convoluted pain (deleting mongo lock file, resetting and losing all the data, etc.) but got nowhere, so am stuck. Best result was the iOS emulator started up with the app, but trying to launch it there just showed a default Meteor screen.
Since Meteor appears to have been developed on OS X machines, there JUST HAS to be a better way of handling this issue than all the workarounds and fixes on >= Yosemite (none of which worked for me)!
Port 3001 is the default MongoDB port (1 more than the Meteor port), so it looks like you’re trying to run meteor ios on the same port that your pre-existing instance of meteor is using for its MongoDB connection.
You can back up the db directory before you delete local directory, and then just put it back in the new local once it’s created. That usually works for me.
Well-spotted, but the same error persists on that (any?) port. Tried again after removing the Mongo lock file at .meteor/local/db/mongod.lock, same error.
Tried this with my working app, (backed up db, deleted local, put db back in new local after doing run ios --port 3010) got:
[[[[[ ~/projects/simple-todos ]]]]]
=> Started proxy.
=> Started MongoDB.
=> Errors prevented startup:

I can only hope that someone looks into this and at least adds a note of caution in the tutorial
My solution was:
move .meteor/local/
meteor run ios --port 3010
wait for the errors
move .meteor/local/ back again
The app then eventually appeared in the iOS Simulator.
I’m not happy at having to jump through hoops to get there. The first warning suggested:
Check that you have permissions to write to .meteor/local. MongoDB does
not support filesystems like NFS that do not allow file locking.
And since my move of .meteor/local/ permissions look like this:

Which seems okay - be interesting to see what others on Yosemite have on initialising a Meteor app, as moving the local folder may have changed things.
