Maropost library started to trigger following error in xCode 12
"error: Building for iOS Simulator, but the embedded framework 'MPPush.framework' was built for iOS + iOS Simulator."
It is connected with fact that library is distributed as ‘fat binary’ (includes binary files for multiple architectures). This mechanism is adopted from mac os and it was never natively handled on iOS. To make this work the redundant binaries are removed from the library at build time.
Your support team suggested I bring up this issue in the Innovation Portal.
