NSKeyedArchiver.archiveRootObject(<#rootObject: AnyObject#>, toFile: <#String#>)
Only returns true the first time. Every next time I call it, the method returns false.
I read some SO, some posts said that I can't rewrite data this way. However, I tried :
NSFileManager.defaultManager().removeItemAtPath(path, error: nil)
and it still didn't help.
What I did:
- Checked all my model files for the
NSCodingprotocol - Checked all my
required init(coder aDecoder: NSCoder)andfunc encodeWithCoder(aCoder: NSCoder)
I am missing something, since I have done this in my last app and it worked fla`

I am using Xcode 6.4 and Swift 1.2.
Any help & code correction is welcome.
