ProblemSlover's solution updated for Swift 2.2:

Important Note: the only change is that now stringByAppendingPathComponent has been removed as of Swift 2.1, so you will get an error saying:

stringByAppendingPathComponent is unavailable: use URLByAppendingPathComponent on NSURL instead.

Please keep in mind that while it may be annoying, it has been removed for a reason and you should follow apple's recommendation to use NSURL instead. BUT if you wish to proceed with this solution, the fix for Swift 2.1+ is to explicitly cast documentsPath to NSString:

class MyImageStorage{
var imagePath: NSString?
}

let url = NSURL(string: "http://images.apple.com/v/home/cb/images/home_evergreen_hero_iphone_medium.jpg")!
if let imgData = NSData(contentsOfURL: url) {
    //Explicitly cast to NSString
    let documentsPath = (NSSearchPathForDirectoriesInDomains(.DocumentDirectory, .UserDomainMask, true)[0] as NSString)
    let writePath = documentsPath.stringByAppendingPathComponent("myimage.jpg")

    imgData.writeToFile(writePath, atomically: true)

    var mystorage = MyImageStorage()
    mystorage.imagePath = writePath

    let realm = try! Realm()
    try! realm.write {
        realm.add(mystorage)
    }
}
