The document Main.storyboard requires Xcode 8.0 or later

Solution 1:

I have figured it out:

Open your Storyboard in Xcode 8.

Click on the File Inspector.

In Interface Builder Document section, select Opens In "Xcode 7.x" instead of "Latest Xcode (8.0)", as in following screenshot:

On doing this, you will get an alert saying "Saving for Xcode 7.x will close your document and data for Xcode 8.0 features will be removed."

Click Save and Close and you will be able to open storyboard in Xode 7.x.

Solution 2:

I have a solution:

1. Open storyboard as "source Code" (right click on storyboard -> open as -> source code).
2. Delete this row:

<capability name="documents saved in the Xcode 8 format" minToolsVersion="8.0"/>

3. Delete this for all storyboards which you are using.
4. Run app.

Solution 3:

It's work for me

Right,click on main.stoaryboard.Go to open as -> source code and change dependencies

change

 <capability name="documents saved in the Xcode 8 format"
     minToolsVersion="8.0"/>  to

   <capability name="documents saved in the Xcode 7 format"
     minToolsVersion="7.0"/>

Follow the same step on launchscreen.stoaryboard
