I’ve finished the book up to page 99. I’m at the bottom where it says to build and run the application. The build is successful, but I believe it’s crashing, and I get the error message “Application windows are expected to have a root view controller at the end of application launch”. The following line in HypnosisView.m is highlighted green.
UIBezierPath *path = [[UIBezierPath alloc] init];
I’ve tried a number of solutions online, but none seem to work or even relate to this project.
