@end

and also when i add these flags $(inherited) -ObjC -l"ConnectSDK" -l"icucore" -l"z" -framework "GoogleCast" -framework "SystemConfiguration"
to other linker flags
i get this error

ld: 35 duplicate symbols for architecture arm64

thx in advance

i fixed the problem by making a new xcode project then
installed all libraries include connectsdk by cocoapod after that i moved all my files from older project to the new one

@hassan379
can you share the project that you configured?
