Building an iOS App is the process of creating an iOS app to publish it that makes your IOS applications available to the users. You release your application through an application marketplace, such as an IOS App store. Building an iOS app involves the following five steps:
You first need to register for the Apple Developer Program to publish an iOS app. Register yourself on https://developer.apple.com/
Apple requires a certificate and provisioning profile to be created for every app published on App Store. For more information on how to generate certificate and provisioning profile, please refer Generating IOS Certificate.
After the certificate and provisioning profile have been created, you need to upload it to your store. You can configure the signing keys in Mobile Apps > Mobile Signing Keys section in StoreHippo Admin Panel.
Once you are done with the setting up of the app, you now have to make your app live on the store. To know how to publish mobile App on the App StoreRegister refer to Creating an iTunes connect.
