In Android, we do not need to configure anything in the Play Store Console before we have the apk ready for publishing. After we have it, we can create a registry on the Play Console; fill the description, details, and marketing settings; then, we upload our apk file and publish.
Remember, you need to be enrolled in a developer program to be able to publish on the App Store. (This also applies to register an app on App Store Connect). Also, check the official guide for more information: https://help.apple.com/app-store-connect/#/dev2cd126805.
In iOS, the process is different. The upload and publishing are managed inside Xcode, so to upload the app, we first create a record on the App Store Connect, fill descriptions, and then, on Xcode, we build and upload our iOS app. To register the app, perform these steps:
- Every iOS application is associated with a Bundle ID, a unique identifier registered to Apple. First, we create a record in App IDs (https://idmsa.apple.com/IDMSWebAuth/signin?appIdKey=

(For our Favors app, it's almost the same value as Android's applicationId).
After realizing these steps in App Store Connect, we finish the process in Xcode.
