Appcode will not run an App that has no developer certificate

Question

I have an app I am writing for iOS that will run just fine in Xcode but AppCode by Jetbrains says :

Error:Code Sign error: No code signing identities found: No valid signing identities (i.e. certificate and private key pair) matching the team ID “(null)” were found.

So what I've been doing was keeping Xcode running so that I can hit the "play" button to deploy/compile my app while doing my actual work in AppCode.

Any ideas what could cause this?

madhurtanwani's link above helped, but I had to scroll to find the solution.

Here is the section that explains the issue and how to solve it:

It looks like in AppCode you are building for a device and in Xcode for a simulator. Simulator does not perform code signing, so you don't get an error there.

If all you want to do is to run the app in a simulator, then in the toolbar change the selection from "iOS Device" to a desired simulator. To be able to sign the app you need to make sure that you have correct provisioning profile and certificate installed and check your codesign build settings.

I had a similar issue and this link on their support site helped me: https://devnet.jetbrains.com/message/5509981#5509981

The crux is that on Xcode I was building for a simulator and in AppCode it was building for an actual device (which requires signing)
