code signing blocked mmap()

I get the following error message when I'm running the app on my iphone:

dyld: Library not loaded: @rpath/Forge.framework/Forge
  Referenced from: /var/containers/Bundle/Application/xxxxxxxxxxxxxxx/Inception.app/Inception
  Reason: no suitable image found.  Did find:
    /private/var/containers/Bundle/Application/xxxxxxxxxxxxxxx/Inception.app/Frameworks/Forge.framework/Forge: code signing blocked mmap() of '/private/var/containers/Bundle/Application/xxxxxxxxxxxxxx/Inception.app/Frameworks/Forge.framework/Forge'
(lldb)

also a warning:
