I am running my app from xcode to my iOS device and I get this and black screen on iOS device.
Console text:
dyld: Library not loaded: @rpath/libswif
For me has worked set the option
ALWAYS_EMBED_SWIFT_STANDARD_LIBRARIES
to YES in Project -> Build Settings -> Build Options
(Namirial framework through Cocoapods)
For Me restart simulator solved this problem.
I had to switch 'Embedded Content Contains Swift Code' to 'Yes' to get my Obj-C app to work after updating the Obj-C embedded framework with a Swift object.
