Trying to create the simplest example similar to the JetBrains Screencast did not work.
Problem 1: After creating the basic project, no "xib" file was shown in Appcode 3 so I could edit the form. I had to first go into XCODE and create a view/form before it showed up in Appcode. I created a single view application for iPhone just like the example video on JetBrains.
Problem 2: Trying to run the form created in xcode now in AppCode gave me two errors (in Appcode). Here is one of them:
Error:Code Sign error: No matching codesigning identity found: No codesigning identities (i.e. certificate and private key pairs) matching “iPhone Developer” were found.
(Note that the view/form runs fine in XCODE).
