Brazil, who had already qualified, finished on top on goal difference with six points and will face South Korea in the last 16.
Switzerland finished with six points, level with Group G winners Brazil but behind on goal difference.
Brazil joined champions France to become the second team to secure a place in the knockout phase.
A largely featureless game had been meandering towards a goalless draw when Casemiro struck seven minutes from time to take Brazil to six points at the top of Group G.
Tite is optimistic about Neymar's recovery from his injury and that he will have his talisman back in time to help them win a record-extending sixth World Cup title.
The 25-year-old refused to celebrate the goal on his 60th international appearance, lifting his hands in the air and frowning as the small group of Swiss fans cheered wildly at Al Janoub Stadium.
