iOS: Changing the story board doesn't reflect on the simulator using a Tab View Controller

Question

iOS newbie here.

I created a new "Tabbed Application" Project on Xcode. The storyboard had a tab view controller and two tabs by default called Item 1 and Item 2.

I deleted the two default tabs, created three new view controllers and connected them to the tab view controller, which gave the tab bar view controller three tabs.

This is the storyboard:

This is the simulator:

Answer 1

So, I fixed it by deleting the app from the simulator and building it again. Must have been a bug with the simulator. :/ Thanks everyone!
