Has anyone else seen an iOS popup warning (it only appears once) which suggests switching to another device and then linking to the following article: Using the Latest Code Signature Format
In this article it suggests that a future release of iOS will make the new code signature format mandatory and that apps using the old signature format will no longer launch. No future release version is mentioned so it is unknown when exactly this will come into play.
The article suggests that you can just re-sign your app and gain the newer format. However, I have tried the steps given and can’t get a code signature format value higher than 20400 which caused the warning to appear. Has anyone else been able to follow the steps and get a value of 20500 or higher?
I do not know if this is something that the Volt builder building process can affect.
Note: this does not affect apps that are distributed through the App Store or TestFlight as App Store Connect does the re-signing for you.
