Hello, I am working on my first app and am almost ready with it, except it needs little finishing in terms of UI and have to add unit tests. I would like it to submit the app to the app store. Since it's first time for me, am confused or need more info on some of the below questions: - Testing - How do you test (like do you distribute the app to friends or test on your own) and how much time you spend testing your own app before submitting it to app store? - Devices - I am presently using simulator and would be buying an Apple device to test my app on the device before I submit. However, presently I would only be able to buy one device, so how do you test if it works fine on all the devices? Thanks!
