After some digging through the storyboard source code, it turns out that the iPad storyboard was copied from the iPhone storyboard. So, the question really became how do I convert an iPhone storyboard into an iPad storyboard?

The answer is surprisingly simple. I ran across this SO answer -- to convert an iPhone storyboard to an iPad storyboard, do the following:

From Xcode, right-click on the storyboard and choose Open As -> Source code
Search for targetRuntime="iOS.CocoaTouch"and change it to targetRuntime="iOS.CocoaTouch.iPad"
Right-click on the storyboard again and choose Open As -> iOS Storyboard
The storyboard will now show all views in the correct size.

Development Phase:

Step 1: Create Certificate .pem from Certificate .p12
Command: openssl pkcs12 -clcerts -nokeys -out apns-dev-cert.pem -in apns-dev-cert.p12

Step 2: Create Key .pem from Key .p12
Command : openssl pkcs12 -nocerts -out apns-dev-key.pem -in apns-dev-key.p12

Step 3: Optional (If you want to remove pass phrase asked in second step)
Command : openssl rsa -in apns-dev-key.pem -out apns-dev-key-noenc.pem
