Looks like the layoutIfNeeded call inside the updateTabCount is causing performance issues because it's relaying out all the subviews in order to calculate the cloned button's frame. A solution would be to statically set the button frame and not rely on the view to layout to determine the view's frame.

Does this need to be sec-sensitive?

Added some changes to improve the startup time of the app. Removed the layoutIfNeeded call when updating the tab count as it's not needed. Also removed the showToolbars call that was happening when the user selects a tab as the toolbars will always be shown if we are selecting a new tab and not calling it avoids a layout pass.

Merged.
