An Xcode Snippet for Singleton implementation in Swift

Swift-Singleton-Snippet

class <#ClassName#> {
  class func sharedInstance() -> <#ClassName#> {
    struct Static<#ClassName#> {
      static let sharedInstance = <#ClassName#>()
    }
    return <#ClassName#>.sharedInstance
  }
}

/* You might ask why there is no GCD related calls here with the obvious dispatch_once/token pair here. 
   Well in fact Swift does this for you under the hood, yes: Global and static properties are already dispatch_once'd 
*/

Swift FTW !
