Apple App Store:
Xcode: Apple requires you to use the latest stable version of Xcode to submit apps to the App Store.
As of today, May 2, 2024, that would be Xcode 15 or later. You can find the latest version on Apple’s developer website: https://developer.apple.com/
iOS Version:
While Apple doesn’t explicitly state a minimum required iOS version for new apps, it’s generally recommended to support the latest two or three major iOS versions to reach a wider audience. However, they might reject apps that target very old and unsupported iOS versions due to security concerns.
Google Play Store:
Android Studio:
While not strictly mandatory, Google recommends using the latest stable version of Android Studio for optimal development experience and adherence to best practices. You can find the latest version on the Android developer website: https://developer.android.com/studio
Minimum SDK Level:
Google Play has a minimum target API level requirement for new apps.
As of August 31, 2023, new apps must target Android 13 (API level 33) or higher.
This ensures your app can leverage the latest features and security improvements in the Android platform. Existing apps need to target at least Android 11 (API level 30) to remain available to users.
