I would have to wonder about the swordtail and molly breeding... how long have you had the molly? Keep in mind that with livebearers, the body has the ability to retain sperm. With this in mind, that means that if a female molly has mated with 5 male mollies in a store tank, then moved to a tank with a swordtail, the molly will still have up to 5 or more batches of "molly fry" from the males she previously mated with. You can take home a single female molly, put her into a tank alone, and she can have fry for up to 6 months or more before she's through. This is the problem in trying to breed livebearers for specific traits, you never know how long you have to wait until you know for sure which male has fertilized her eggs. Average time span to create a new color strain that is pure is about 2 yrs.+
And, regarding the original post...
Be prepared to have a lot of fry, which means a lot of fluctuation in water quality. Most live bearers will produce about 30 fry at a time, but can have more than 40, and they can do this about every 30 days. If you are keeping these fish in a small tank, be on alert for overpopulation each time a fish gives birth, thus water quality that can quickly hit toxic levels. I suggest daily water changes of 10% in a livebearer tank if it's under 55 gallons or is heavily stocked with females. Another thing to remember is that their favorite activity is breeding, so keeping 2 females for each male is also a must. The males will chase the females until they exhaust them to death, literally, if there are not enough other females to chase. Heavy decoration is also called for in a livebearer tank, the smaller the tank, the more decorations needed.

I have some blue platties and show guppies in my community tank.

In addition to "planted plants" and plants tied to wood at middepth of the tank I have a grouping of Anacharis tied to wood at the surface.

These Anacharis do not "grow to the wood" and are not published to be floating plants but they grow to form an very good area for birthing of the live bearers as well as cover for their fry. (The angels which I am growing frequent the perimeter of this growing area but the area is of sufficient densiy that the angels do not "get into it".)

I have the grouping of Anacharis tied to the wood only to keep them from floating across the surface of the tank and also to prevent them from clogging the return slots to the wet/dry filtration process.

It is intersting that a sword and molly bred, wil be intersting to hear if the fry are born alive or not.

Guppies, mainly the fancy guppies will breed with mollies. I have seen this first hand. Platties and swords as stated before. Also, most cory species will crossbreed.
