Apple has changed the codesign signature to include DER encoded entitlements in addition to the plist encoded entitlements. This additional DER encoded entitlements section is required in iOS 15 and becomes the default behavior of codesign in the latest Xcode. To use codesign on an older machines with an older version of Xcode add the --generate-entitlement-der flag to your call to codesign. If signing through Xcode, you can add this flag to the OTHER_CODE_SIGN_FLAGS setting in the Build Settings tab. from here: https://stackoverflow.com/a/68467307/7033956
