Problems with OneSignal library at build time##

If you are experiencing any type of issue related to the OneSignal library when building iOS, e.g:

ld: warning: directory not found for option '-L/example/build/ios/Debug-iphonesimulator/onesignal'
    ld: library not found for -lonesignal
    clang: error: linker command failed with exit code 1 (use -v to see invocation)

Could not build the application for the simulator.
Error launching application on iPhone 6.

Try following the following commands:

pod deintegrate
pod install

Distribution Error: Found an unexpected Mach-O header code

Both of the following solutions have been reported to work:

Solution 1

1 . Go to Runner and then to Build Settings and set Always Embed Swift Standard Libraries to YES
2 . Then go to OneSignalNotificationServiceExtension and then to Build Settings and set Always Embed Swift Standard Libraries to NO

Solution 2

  1. Set config.build_settings['ENABLE_BITCODE'] = 'YES' in your Podfile.
  2. Set all ENABLE_BITCODE = 'YES' in the Runner project
  3. Set the importance of ALWAYS_EMBED_SWIFT_STANDARD_LIBRARIES = 'NO' in the Runner app.
