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?

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

Thanks @jpsim. That gives me a file URL now. But the app crashes with the same exception nevertheless. – Prasanna Dec 09 '14 at 03:29
Try writing an empty file with NSFileManager to see if you have sufficient permissions: `NSFileManager.defaultManager().createFileAtPath(path, contents: nil, attributes: nil)`. The app group may not have been created properly. – jpsim Dec 09 '14 at 20:20

The issue was I need to use directory.path! rather than absoluteString. – Prasanna Dec 11 '14 at 09:18
How would you achieve this in iOS9 / Swift 2.1? – Lachtan Jan 29 '16 at 01:41
just change the second line to this: `let realmPath = directory.URLByAppendingPathComponent("db.realm").path!` – jpsim Jan 29 '16 at 15:58

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

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

It has changed again, now:

let configuration = RLMRealmConfiguration.default()
configuration.pathOnDisk = realmPath
RLMRealmConfiguration.setDefault(configuration)

In Xamarin, you can do somethings like this to change default configuration path of Realm from Document to Library directory for Xamarin iOS app:

// Get path of Library directory first

var directoryLib = Environment.GetFolderPath(Environment.SpecialFolder.Resources);

//Configure your own path

var myOwnRealmPath = Path.Combine(directoryLib, "boards.realm");
RealmConfiguration.GetPathToRealm(myOwnRealmPath);

// Change default configuration path to your own (Here I have changed to Library directory)

RealmConfiguration.DefaultConfiguration = new RealmConfiguration(myOwnRealmPath);

//Get Realm Instance from your own designed path

_realm = Realm.GetInstance(RealmConfiguration.DefaultConfiguration);
