When I run my application In simulator it shows some autolayout errors

Question

his application is modifying the autolayout engine from a background thread after the engine was accessed from the main thread. This can lead to engine corruption and weird crashes.

Answer 1

Try this:

It needs to be placed inside a different thread that allows the UI to update as soon as execution of thread function complete

DispatchQueue.main.async 
{
   // Update UI
}
