Good morning
we have a problem with app on the iPad.
After installing access to IOS 14.3, when opening the app (only the first time) compare the message:
“This app will not work with future versions of iOS. The developer of this app needs to update it to improve its compatibility”
and referring to the link:
https://developer.apple.com/documentation/xcode/using_the_latest_code_signature_format
indicating:
"Look in the output for a string like CodeDirectory v=20500. For any value of v less than 20400, you’ll need to re-signed your app.".
From a verification performed on Mac, it appears that our app has CodeDirectory v = 20200.
It should be noted that we develop the platform through Adobe AIR and the compilation takes place on a PC Winsows. We need to understand what has changed between CodeDirectory v = 20200 and CodeDirectory v = 20500 in order to adapt our build systems to the new Apple requirements.
Thank you for the support

We need to understand what has changed between CodeDirectory v = 20200 and CodeDirectory v = 20500 in order to adapt our build
systems to the new Apple requirements.

Apple does not document code signing at that level. The only supported way to sign code for our platforms is to do that signing on the Mac. If you’re signing code on another platform using a third-party tool, you should talk with the tool’s vendor about this issue. If you’ve built your own signing infrastructure, you must have reverse-engineered the signing format yourself, in which case you’ll need to do this again for the latest version.

MarEGMco,

Would you mind sharing if you've found a solution for this issue?

We are in the same scenario as yours - we develop the platform through Adobe AIR and the compilation takes place on a PC Winsows. We compile the IPA via Adobe Animate.

There seems to be no information to be found....

Thank you so much!
