I found the way how to update the layout based on language selection using UISemanticContentAttribute.

if(IS_OS_10_OR_LATER) {

    if ([[[NSUserDefaults standardUserDefaults] valueForKey:@"Ln"] isEqualToString:@"Ar"])
        [[UIView appearance] setSemanticContentAttribute:UISemanticContentAttributeForceRightToLeft];
        [[UIView appearance] setSemanticContentAttribute:UISemanticContentAttributeForceLeftToRight];

As I had stored the current language selection in NSUserDefaults and accordingly update the layout.
