When I called Apple support about my watch inaccurately counting swim laps I was told that inaccuracy was to be expected and to just "live with it." Is that really true.
I have been told it uses GPS to count laps and the length is dependent on the GPS lap counting.

This is a user-to-user forum. Almost all of us are simply users as yourself. If that is what you were told by Apple, who are we to argue? All I can suggest is that you set the lap length to a slightly different value to compensate.
Swim with your Apple Watch - Apple Support
For Pool Swim, turn the Digital Crown to set the pool length. This helps your Apple Watch accurately measure your laps and distance.
I'll try your suggestions. This morning was the worst. I swim about a mile a day (32 lengths or 16 laps in a 50 meter pool). Today it said I sway 1100 meters when I actually swam 1700 meters. I just use my watch now for time and "move" since the is such a wide discrepancy in the lap or length counting. Several IT experts (not Apple support) have told me that there are different accuracy levels associated with different GPS devises and they suspected that the Apple Watch probably did not have a very high quality one built in to the watch which was accounting form the errors.
And the strokes used as calculated by my Apple Watch is useless. I have use a systematic series of strokes to keep track of the laps and today it said I did backstrokes or breast strokes which was not true in the least.
