Detailed explanation of the latest process for submitting Apple iOS APPs for listing, a practical guide for novices to list on the App Store!

Let me first briefly talk about the steps of listing IOS APP (see the figure below for detailed steps):

Create a certificate request file

Log in to the Apple Developer Center to generate a publisher certificate (double-click after downloading)

Set APPID (Bundle ID is needed, it is recommended to copy it from XCode so that you don’t have to change the Bundl ID in the XCode project, otherwise you have to change it)

Generate a configuration file (to use APPID and certificate, exit XCode and double-click the configuration file to open the project)

Create a new APP project in iTunes Connect in the Developer Center and configure the corresponding information (screenshots of various versions are required, run the simulator, adjust it to the maximum (command+1), use command+S to take screenshots (if your keyboard does not change the command key), and a 1024*1024 icon without rounded corners)

Set some properties of XCode (mainly select configuration files and certificate accounts, etc.)

Package and upload your program

Details are as follows:

Create a certificate request file

Next is the certificate request file, some people call it the CSR file, which will be used for the certificate later.

First, open Applications -> Utilities -> Keychain Access (KEY CHAIN), in the upper left corner of Keychain Access -> Certificate Assistant, select "Request a certificate from a certificate authority", as shown below:

In the interface shown in the figure below, your email address: fill in the name of the developer account you applied for, that is, the username you use to log in to the Apple Development Center, common name, any name but it must be easy to find. It is recommended to put it together with the APP materials, but this can be stored in a separate folder. CA is empty, choose to save to disk, click "Continue", and then complete. As shown in the figure:

With the certificate request file, you can create a certificate

Find the Member Center of the Apple Developer Center

https://developer.apple.com/

As shown in the figure:

Enter the company or individual developer account and password, as shown in the figure:

Create a certificate

Then log in and the following interface will appear: Click Certificates, Identifiers & Profiles

Then you will see the picture below. Continue clicking as shown below.

Then you can create a certificate file, select

Just like creating the APPID before, create a certificate file, and you need to use the file just now, as shown in the figure:

Then continue to this interface, you need to select the certificate request file you just downloaded, make sure you don’t make a mistake, as shown in the figure:

Download Certificate

Then Done, double-click the downloaded certificate to import it into the keychain.

Next, go to APPID and set the application name (just remember it, you will need it later) and Bundle ID (it is recommended to copy it directly from XCode)

Then create APPID

As shown in the figure:

Then continue, Submit, Done.

Then create the configuration file

Then continue,

Then Done, exit XCOde and double-click the configuration file, XCode will start and open the project.

Then log in to ITunes Connect and create a new APP

In the upper left corner, click + to create a new APP

Next, you need to configure some application information. Try to fill in all the information that is not optional.

As shown in the figure:

It is best to have several pictures for each version. The source of the pictures is to run all the simulators, adjust them to the maximum with command+1, and then command+s.

Next is the configuration of XCOde. HEHEHEHE is the name of the configuration file.

That’s all I have to explain.

All that's left is to package and upload it.

Select the simulator device

As shown in the figure:

Then there is

Compile in Project->Archive

Then you can upload it to the APPStore

The last step is to log in to the Developer Center and find the iTunes Connect APP

Find the one you want to submit, and then find the APP you just uploaded in the built-in version, as shown in the figure:

Then click Submit for review.

Here comes the point

I died many times in this place below

As shown in the figure:

In the end, the problem was solved because a certificate had expired. I just deleted it and downloaded another one:

Open Keychain

Show all expired certificates

3. Delete the expired Apple Worldwide Developer Relations Certification Authority certificate in 'Login' and 'System' ('System' needs to be deactivated to delete)

4. Download the new Apple Worldwide Developer Relations Certification Authority certificate and double-click to install it.
