Build a simple IOS app with Swift 3 errors when run?

Not sure what went wrong when I created the IBOutlet for the label and misspelled it and then tried to remove it and rename it and ran it. Now I can't get it to work.

Here are screenshots of what I got after problems occurred.

What's going wrong? How do I fix things?

The problem was that when you renamed the IBOutlet the old name of the IBOutlet was still held on the label. to fix it first go to Utilities at the top right, then go to Connections Inspector, then go to Referencing Outlets and you'll see the old name of the IBOultet. Click the x to erase and then add the new IBOutlet to the label.

Hi Luis,

Thanks for your reply.

When I go to the storyboard, I get the following ... what is going on?

Because at the top right you selected, Show the version editor, it looks like two opposite arrows. To fix it go and click on, Show the Standard Editor, which looks like 5 lines on top of each other which is near the, Show the version Editor.
