I modally present a view controller, and then present an activity view controller. However when I do, the app crashes with error:
libc++abi.dylib: terminating with uncaught exception of type nsexception ios 10 "self.present"
This is what causes the app to crash:
let vc = UIActivityViewController(activityItems: [shareText], applicationActivities: [])
self.present(vc, animated: true, completion: nil)
I modally present the view controller with just a segue
self.performSegue(withIdentifier: "showContainer", sender: nil)
