Build failure -- sq3lite undefined symbols

[Jeremy Bone]

After downloading and successfully building the iOS framework per the Github instructions (there's actually no "CBL iOS" scheme--the target is named that but the scheme appears to be called "Continuous iOS") and then adding it to my project, I get a host of undefined symbol errors related to sq3lite (included below) when building my project. I'm assuming they are related to the sqlite-unicodesn submodule, but have no idea why it's occurring.  Any ideas?

Hm, I fixed that in the wiki last week. Were you working from the summary in the readme itself? I just looked at it and it still has the wrong name. I’ll fix that.

and then adding it to my project, I get a host of undefined symbol errors related to sq3lite (included below) when building my project.

Did you remember to add the sqlite3 library to your app target? See step 3.1v in “Linking Couchbase Lite Into Your Own App”.

Also, for most users we recommend downloading the pre-built framework, to save the kind of trouble you’re running into. Unless you’re really into DIY or want to make sure you’re on the bleeding-edge master branch, it’s easier to avoid building it yourself.
