Hi there. I have recently added swift framework to my project. There is also Objective-C wrapper plugin for calling this framework's functionality. Seems that UCB doesn't support swift plugins, because once app built and runned on device, there is an error: dyld: Library not loaded: @rpath/libswiftCore.dylib Referenced from: /private/var/mobile/Containers/Bundle/Application/...<used swift framework> Reason: no suitable image found While, if I compile this project on Mac OS and run on device it's going well. If before compiling project in XCode set ALWAYS_EMBED_SWIFT_STANDARD_LIBRARIES to NO, same issue appears as in UCB build. Added iOS post processing settings: ENABLE_BITCODE = NO OTHER_LDFLAGS = -ObjC -v CLANG_ENABLE_MODULES = YES LD_RUNPATH_SEARCH_PATHS = $(inherited) $(SDKROOT) @loader_path/Frameworks @executable_path/Frameworks SWIFT_VERSION = 3.0 ALWAYS_EMBED_SWIFT_STANDARD_LIBRARIES = YES EMBEDDED_CONTENT_CONTAINS_SWIFT = YES Also, this swift framework added as additional copy files build phase to 'Frameworks' location. Apps/OS versions: MacOS Sierra 10.12.6, Unity 2017.1.1f1, XCode 8.3, swift 3 Tested devices: iPhone 5 (iOS 10.2), iPhone 6+ (iOS 10.3) Does anyone successfully built app on UCB with swift plugins or encounter with such error?
