My puzzle generator has limitations. That said ...

Code:
 +-----------------------+
 | . . 6 | . 5 . | . . . |
 | . . 7 | 9 . . | 5 3 . |
 | 5 8 . | . . 6 | 9 . . |
 |-------+-------+-------|
 | . 6 . | 2 . . | . 4 3 |
 | 4 . . | . 9 . | 6 . . |
 | . . 2 | . . 4 | 1 . . |
 |-------+-------+-------|
 | . 9 4 | . 6 3 | 8 . . |
 | . 5 . | 1 . . | . 6 . |
 | . . . | 8 . . | . . . |

A very enjoyable puzzle requiring several moves including
Type 1 UR <59>
Type 3 UR <28> with an x-wing on <8> ( again, a Weasel)
A x-wing on <1>
a Swordfish on <2> and finally
A xy-wing on <123>


I suspect the xy-wing would have solved the puzzle quicker, but I tend to follow a specific sequence and just take what I can find.

Two X-Wings (1 and 3) and a W-Wing (1 and 3) do it.

When generated, my puzzles were limited in the techniques allowed to solve them. Of course, my technique hierarchy isn't perfect.

Code:
 r5  b6  Locked Pair                     <> 28   [r6c89]
 r5  b6  cloned Pair                     <> 28   [r5c6]
   c5b8  Locked Candidate 1              <> 4    [r23c5]
 r1  b3  Locked Candidate 1              <> 8    [r1c6]
   c5b5  Locked Candidate 1              <> 8    [r2c5]
   c8    Naked  Quad                     <> 1278 [r9c8]
 r24     X-Wing                          <> 1    [r3c5],[r7c1]
 r15     X-Wing                          <> 3    [r69c2],[r3c4]
 r9  b7  Locked Candidate 1              <> 1    [r9c9]
   c267  Swordfish (233)                 <> 2    [r1c89],[r8c159],[r9c59]
   c5b8  Locked Pair                     <> 47   [r89c6]
   c5b8  cloned Pair                     <> 47   [r3c5]
   c6b8  Naked  Pair                     <> 29   [r1c6]
         XY-Wing  [r3c3]/[r2c1]+[r3c5]   <> 2    [r2c5]
         XY-Wing  [r3c5]/[r2c5]+[r3c3]   <> 1    [r2c1]
