What changes as a developer need to change in the code base for iOS13 SDK
I have changed the target and build the app, Its working fine apart from that do we have to implement signing with apple as mandatory changes for ios 13 to accommodate as per guideline

Below are the things apple has sent on mail to cross-verify

• Apps for iPhone or iPad must be built with the iOS 13 SDK or later and use an Xcode storyboard to provide the app’s launch screen.

• iPhone apps must support all iPhone screens and all iPad apps must support all iPad screens.

• Apps for Apple Watch must be built with the watchOS 6 SDK or later.

• Apps that authenticate or set up user accounts must support Sign in with Apple if required by guideline 4.8 of the App Store Review Guidelines.

• Apps in the Kids Category must be in full compliance with guideline 1.3 and guideline 5.1.4. of the App Store Review Guidelines.

• Apps using HTML 5 must be in full compliance with guideline 4.7 sections 4, 5, and 6 of the App Store Review Guidelines.

Answer 1

the message simply means that any developer looking to either release a new app or an update to an existing app on the App Store will have to build it using iOS 13 SDK.

If there is not proper need to update your app, then you can ignore the message !
