What is a “development-signed version” of an iOS app? How do I run a development-signed version of my app?

Question

I am trying to test in-app purchases on an iOS device. At Create a sandbox tester account it says:

To connect to your development servers and the test environment for the App Store, run a development-signed version of your app and sign in using a sandbox tester account.

The problem is, I don't know what a "devepment-signed version" is, or how to run one.

In Xcode I have one app target, and under "Signing & Capabilities", "All", "Debug" and "Release" have "Automatically manage signing" checked. I cannot find a way to run a "development-signed" version and am not having luck figuring this out by Googling. Does this have to be a physical device, or can it be a simulator?

Answer 1

When you connect a device to a mac, then build your app and send it down to that device, you are then running a development-signed version. It can't be done on a simulator.
