I'm trying to install facebook SDK using swift 4 (xcode version 10.1) and it doesn't work. The error says
'SWIFT_VERSION '5.0' is unsupported, supported versions are: 3.0, 4.0, 4.2. (in target 'FacebookCore')'
'SWIFT_VERSION '5.0' is unsupported, supported versions are: 3.0, 4.0, 4.2. (in target 'FacebookLogin')'
Is there any way to fix this problem without upgrading the swift version to 5.0?
