you want call some closure in swift code then you want to change in storyboard ya any type off change belong to view your application will crash

but you want to use dispatch method your application will not crash

async method

DispatchQueue.main.async 
{
 //Write code here                                   

}

sync method

DispatchQueue.main.sync 
{
     //Write code here                                  

}
