How to Preload 'Realm' DB into iOS swift3?

I am trying to implement Realm database in my app , I have realm database with some Preloaded data into it . I have searched through many stack overflow resources but didn't get any success.

So far now , I have done following steps :

  1. Copy the Realm File into my app's bundle

  2. Added following code in the app delegate :

    path = Bundle.main.path(forResource: "data", ofType: "realm")
var config = Realm.Configuration(fileURL: NSURL(fileURLWithPath:      path!))
config.readOnly = true

// Open the Realm with the configuration
let realm = try! Realm(configuration: config)

But this doesn't work , Please provide some solution to it .

Note : I don't want to migrate my database.

Thanks in advance

Select your realm file in Xcode Project Navigator then go open file inspector pane and check Target Membership box for your current target. Your code will work already!

The piece of code below works perfectly for me to load a preloaded Realm instance during the first launch of my app:

let defaultPath = Realm.Configuration.defaultConfiguration.fileURL?.path
let path = Bundle.main.path(forResource: "default", ofType: "realm")
if !FileManager.default.fileExists(atPath: defaultPath!), let bundledPath = path {
    do {
        try FileManager.default.copyItem(atPath: bundledPath, toPath: defaultPath!)
    } catch {
        print("Error copying pre-populated Realm \(error)")
    }
}
