iOS engineer tech stack at Snap

Hello! Currently evaluating whether to work at Snap as an iOS engineer. What is the tech stack that they use? And what is your experience with using it? Mainly interested on whether it’s mainly native development or if it uses Composer (the cross platform framework). For the latter I wonder if it’s a good environment if you would want to develop fully in objective C or swift! #engineering #software #swe #snap #ios
