In addition @Mc.Lover 's answer, If you want to aplly this change to all of your tab bar Items in application, I recommand to add the code in application function of AppDelegate class:

    //Just add this line to get it done.       
    UITabBarItem.appearance().setTitleTextAttributes([NSFontAttributeName: UIFont(name: "IranSansMobile", size: 15)!], for: UIControlState.normal)

    return true
}
