[Urgent] app packged with Xcode16 crashed on iOS12

I have just found the same issue. Updated App is failing, checking the console shows that bootstrap failed with error unable to obtain valid process handle. I have several users reporting issues after upgrading

is it known issue for Apple team?

No. Nobody uses iOS 12 anymore, so nobody knows of any issues when it runs apps built with Xcode 16. In Xcode 16, I can't even set a deployment to anything earlier than iOS 15.

to resolve this issue, what can we developers do?

You can drop support for anything before iOS 15, or Use an older version of Xcode.

Our project must fit iOS12 because we are business projects. iOS15 is too high for us. It is unacceptable for us to raise iOS deployment version from iOS12 to hgiher version.

Help! Need Apple team to reply

I’m not sure what sort of reply you’re expecting here. Our Developer > Support > Xcode article makes it clear that Xcode 16 has a minimum deployment target of iOS 15. Given that, we don’t support folks using it to build for iOS 12. If you do it anyway, you’re likely to encounter weird behaviour.

Until recently you could get around this by using Xcode 15. However, that’s no longer an option, presuming that you’re shipping on the App Store.
