Hi there, i am developing a mac os application, actually i am facing problem in the child window, the button click event is not working in the child window even if i have done everything correctly. The buttons in parent window (Window displayed when application starts) are working fine, when i go to another window by clicking the sign in button the buttons in that second window is not working. Can anyone help me to solve this please.
I am using Xcode9, swift4.
