The South African model announced her engagement to Hermann Nicoli in August 2015. The couple share two sons: Anacã, who they welcomed in 2016, and Ariel, who arrived in 2018. The pair split up in November 2018 but continue to coparent their children. In 2021, the 34-year-old businesswoman launched her line of eco-friendly and sustainable swimwear pieces under the brand name Tropic of C.
"I wanted the line to be something I could be proud of from all angles, not just adding to the problem. I want to leave the world a better place, not worse," she told Fashion Week Daily in April 2021 about her brand, which she models herself.
Swanepoel is also actively involved with the nonprofit Mothers2Mothers, which focuses on raising awareness regarding mother-to-child HIV transmission. She joined the charity as its global ambassador in 2019.
