**I would like to know if you see any architectural pitfall of this approach.**  
1/I don’t want to create navigation and toolbar buttons by dragging on storyboard.  
2/Using navigation controller to have Navigation bar and tool bar on every View  
3/I define butons and action in global appConst.swift and not to force to do it in every ViewController  
4/I could use same icon in different ViewControllers and not worry about consistency  
5/Make view controller clean of generating buttons  
6/I didn’t specify target at creation of button, but when i am using in actual viewcontroller

**1/Global file for constants appConst.swift**  
_let workCenterIcon = “WorkCenter.png”_  
_let workOrderIcon = “WorkOrder.png”_  
let newWrkCtrAction = “newWrkCtrAction”  
let newWrkOrdAction = “newWrkOrdAction”  
//New work center action  
let newWkCtrBtn = UIBarButtonItem(image: UIImage(named: workCenterIcon), style: UIBarButtonItemStyle.Plain, target: nil, action: Selector(newWrkCtrAction ))  
//New Work order action  
let newWkOrdBtn = UIBarButtonItem(image: UIImage(named: workOrderIcon), style: UIBarButtonItemStyle.Plain, target: nil, action: Selector(newWrkOrdAction))  
let spaceBtn = UIBarButtonItem(barButtonSystemItem: UIBarButtonSystemItem.FlexibleSpace, target: nil, action:nil )

**2/In any viewController I could use this globally design and maintain icons**  
override func viewDidLoad() {  
super.viewDidLoad()  
//TOOL BAR\*\*\*\*  
//Setup Tool bar buttons  
newWkCtrBtn.target = self  
newWkOrdBtn.target = self  
self.toolbarItems = [spaceBtn,newWkCtrBtn,spaceBtn,newWkOrdBtn,spaceBtn]  
…

func newWrkCtrAction()\_  
{  
print(“tapNewWorkCenterAction”)  
}

```
func newWrkOrdAction()_
{
    print("tapNewOrderAction")_
}

```
