Swift 2 0  Updated version of Ivica M s answer   let wordDict           A     1  2         Z     3  4         D     5  6     let sortedDict   wordDict sort    0 0  lt   1 0   print    sortedDict          Swift 3  wordDict sorted by     0 0  lt   1 0      Notice   Don t be surprised that the resulting type is an array rather than a dictionary  Dictionaries cannot be sorted  The resulting data-type is a sorted array  just like in  Ivica s answer

let dictionary          A     1  2        Z     3  4        D     5  6     let sortedKeys   Array dictionary keys  sorted  lt        A    D    Z     EDIT   The sorted array from the above code contains keys only  while values have to be retrieved from the original dictionary  However   Dictionary  is also a  CollectionType  of  key  value  pairs and we can use the global  sorted  function to get a sorted array containg both keys and values  like this   let sortedKeysAndValues   sorted dictionary     0 0  lt   1 0   println sortedKeysAndValues       A   1  2     D   5  6     Z   3  4      EDIT2  The monthly changing Swift syntax currently prefers  let sortedKeys   Array dictionary keys  sort  lt        A    D    Z     The global sorted is deprecated

If you want to iterate over both the keys and the values in a key sorted order  this form is quite succinct let d          quot A quot     1  2        quot Z quot     3  4        quot D quot     5  6     Swift 1 2  for  k v  in Array d  sorted   0 0  lt   1 0         println  quot   k    v  quot      Swift 3   for  k v  in Array d  sorted by    0 0  lt   1 0         println  quot   k    v  quot
