如何延长我的配置证书对我的 iOS 应用程序的有效时间？

Question

Background

I've written an iOS app which is for "Home Use" at this time. I have a locally provisioned certificate in XCode for my app so I can install it on my devices. I've been running the app for 6 or 7 days on my local iPhone.

App No Longer Available

Today I got the error "App No Longer Available" when I try to run it. I found the SO Entry that lists reason why this might be happening , but I know why. I checked XCode and discovered that the provisioning cert only lasts 6 days. So annoying!! 🤬

Provision App For Longer?

However, I don't know how to provision the app for longer?

How do I set up the cert to last longer?

Can this only be done by having a full apple dev account?
Really hope not.

Answer 1

Finally found the definitive answer at: iOS App says "No longer Available" after my license had been expired? (Though it is not the answer to the other question there.)

Definitive Answer

Without Official Apple Dev Account

If you don't have an official Apple Dev Account provisioning will only last for 1 week. The app will expire every 7 days (or less in some cases -- depending upon the day the initial certificate was created).

With Official Apple Dev Account

You will be able to provision your app for up to 1 year.

This is gleaned from other comments on the linked answer. It may not be true any more.

Here's a partial answer that I got to through a lot of searching.

I found out that in XCode, you can go to :

XCode => Preferences...

A dialog will appear and then you should choose the Accounts tab

There is a manage certificates button here. click it.

You can click the small [+] button on the lower left but it is really unhelpful.

This adds a certificate, but notice that you cannot tell when the expiration date is and the Status column shows no information at all.

There is no way to select or edit any of the certs here.

This is ridiculously complicated. I'm sure it is just to push devs to create an official apple account & pay the fee.
