Hello! I am using macOS Catalina, Xcode 11. I just started working on app development and this is my first project. Every time i try to simulate the code the program crashes and it gives me thread 1 signal SIGTERM error. My code is very simple, I don't think i have an error there. I am really stuck, I tried to run different projects but it doesn’t work on any of them. Please, can someone help me fix this error? Thanks in advance!
