Application crashing in didFinishLaunchingWithOptions

[tleyden]

Here's the code that's crashing:

https://github.com/vinceyoumans/couchbaseLite-vy02-test/blob/master/cblite02/cblite02/AppDelegate.m

Nothing jumped out at me.. though I didn't try to run it.

the problem can be found in AppDeligate.m
I found where is crashes, and left //remarks
but this is straight out of the iOS documents. xCode 5.0

I found a thread in the google group that might be relevant: https://groups.google.com/forum/#!topic/mobile-couchbase/aQw-xwqqkVI - look for the post that starts with "Ugh. Thanks for letting me know" on 12/22/11. Also another thread: https://groups.google.com/forum/#!msg/mobile-couchbase/kAx27QJD4ts/kA-xdCda3B0J

Yea.... I am using xCode 5.
The trick is to add "-ObjC" to "Other Linked Flags"
You can find "Other Linked Flags" in Build Setting.. Linking.
I would guess that this is the same problem with xCode 4

@snej should we add this to the FAQ?

It's already mentioned in the docs in the Adding Couchbase Lite To Your App section, but I agree that it doesn't exactly jump out at you. :)

Back in the day, CouchCocoa's initialization code had a check for this situation and would log a warning telling you to turn on the -ObjC flag. It would be pretty easy to add something similar to CBLManager.
