Navigation Controller UIToolbar does not show items

Hi,

I hope everyone is doing well.

I am new to Xcode and iOs development.

I am using Xcode 6.3.2 (6D2105) and Swift for development.

The problem is, for navigation controller I have selected "Show Toolbar" and then added items to Toolbar but nothing gets displayed when I check in simulator.

But on adding toolbar to other view it starts showing the items. This way I will have to add toolbar to all the views and I do not want to repeat same stuff for all UIViews used in the app.

Is there any option that I need to select or changed any other property?

Do I need to add items to toolbar using code, if this is the case how to do that and where to write the code for the same, in AppDelegate?

Thanks,
Varun
