Hello! I have been creating a chat app and recently came across a few issues. When I log in, the inicial VC is one made of the added users. I can tap on any of them to start a new conversation. My backend is Parse and i store my messages and info there. The problem is that when i tap on the user the messages take too long to load. Is that related to the server or to the simulator itself? I went to the server and got no slow queries.. Also, the app itself responds kind of slowly. When i type on the "Type message" view the keyboard takes some time to appear, it is not immediate and this does not depend on the server. I even tried running the app on my actual iPhone and it is still pretty laggy and crashes from time to time. Is this normal on the development process or should I expect my app to perform better and in real time when i test it on my real iPhone? Thank you in advance.
