why do my sungold tomatoes split

It may be because during the growing period the plants at some point have been allowed to get dry and then heavily watered, which causes fruit to split when it developes

Yes I agree Milky that can happen

Yup! Irregular watering. Tomato plants are like us ... if they don't get a fix of wet at regular intervals they get crabby!
