Called in a transaction When the UIsearch user interface and keyboard are shown

I made a ViewController where there is a button and a UITextfield, when I click the button, the UITableViewController with the UISearchBar is displayed and the list of languages ​​is displayed. My problem is that when I launch the application the first time I click the button and then on the UISearchBar in the console, I have this warning.

SearchDebugApp [2237: 558457] + [CATransaction synchronize synchronization] called inside a transaction SearchDebugApp [2237: 558457] + [CATransaction synchronize synchronization] called inside a SearchDebugApp [2237: 558457] + [CATransaction synchronize] called inside a SearchDebugA transaction 2237: 558457] + [CATransaction synchronization] called in a transaction

this message only occurs the first time I click on a UISearchBar. Nothing seems wrong in the application, so I don’t understand why this is happening and how to debug it.

I looked for this warning, and found out that this happens when several animations happen in the main thread, but in my application only animation happens when the keyboard is displayed.
