I created my very first app using Xcode. I've tried it in the simulator and it worked perfectly.I didn't want to publish it, I just wanted to try it on my iphone.Here's where problems started. When I tried launching the app in my iphone using Xcode, I've been asked to allow keychain sharing. I clickled on allow and the message came back, so I clicked on deny. After that, an error showed up preventing me to launch the app in my iphone.I figured out it's becaue I clicked on deny keychain sharing, so I tried to allow it from somewhere but I couldn't.I started playing with the Keychain Access app on my mac trying to solve the problem. Eventually, I deleted the "iOS Development" certificate desperately trying to solve the initial problem.However, this made the problem even bigger, and I realized I made a terrible mistake by deleting that certificate. How can I obtain it agan?When I tried to launch the app in my iphone through Xcode afterwards, I got more errors and one of them says "No signing certificate "iOS Development" found"Now my biggest concern is the iOS Development certificate; how can I get it back?

First of all, I wanna mention that I'm don't have a paid membership yet.I was trying to launch my very first app on iPhone (Using Xcode).I accidently clicked deny when I was asked to allow Keychain sharing. Therefore, I got an error and I couldn't get it on my iPhone.Xcode never asked again if I would allow/deny Keychain sharing.Desperately trying to resolve the error, I deleted the iOS Development Certificate from the Keychain Access.I didn't know what certificates are at the time, and I didn't know it's a big deal.As you all probably know, this caused more errors and it was obvious that it was a mistake.Now I need that certificate back. How can I get it? KMT provided me a link that seemed to be addressing my problem. This link belowhttps://developer.apple.com/library/content/documentation/IDEs/Conceptual/AppDistributionGuide/MaintainingCertificates/MaintainingCertificates.html#//apple_ref/doc/uid/TP40012582-CH31-SW26However, in the instructtions on how to recreate a certificate, the first step mentioned is to revoke the certificate.Appearently, in the member center I'm supposed to be seeing a section/tab "Certificates, Identifiers & Profiles".I don't see that in my member center!Another mentioned approach to revoke the certificate is to do that through Xcode prefrences under "account". It's mentioned that I should click on the tam then click "View Details". However, I don't see this "View Details" choice.I really need this certificate (the iOS Development Certificate) back, please help.
