Dr. Dominik Hauser completed his PhD in physics at Heidelberg University, Germany. While working as a university professor, he started iOS development in his spare time. His first app on physics has been an astounding success worldwide. Since then, he's turned himself into a full-time iOS developer, crediting a number of successful apps to his name. He has been a Swift developer since day one and runs a blog on iOS development at http://swiftandpainless.com/.
