How to set default realm path to App Groups directory

Question

I am trying to set the default Realm path to App Groups directory.

let directory: NSURL = NSFileManager.defaultManager().containerURLForSecurityApplicationGroupIdentifier("groups.prasanna.appName")!  
RLMRealm.setDefaultRealmPath(directory.absoluteString!)  
println(RLMRealm.defaultRealmPath())  

The app crashes with the following error

Terminating app due to uncaught exception 'RLMException', reason: 'open() failed: Operation not permitted'

How do I fix this issue?

Answer 1

the default realm path you're setting is your container directory. You'll have to append a file name for this to work:

let directory: NSURL = NSFileManager.defaultManager().containerURLForSecurityApplicationGroupIdentifier("groups.prasanna.appName")!
let realmPath = directory.path!.stringByAppendingPathComponent("db.realm")
RLMRealm.setDefaultRealmPath(realmPath)
println(RLMRealm.defaultRealmPath()) // should be realmPath

RLMRealm.setDefaultRealmPath() removed at 0.97 version, you should use this : Tim answer

var config = RLMRealmConfiguration.defaultConfiguration()
config.path = realmPath
RLMRealmConfiguration.setDefaultConfiguration(config)
