‘ld: warning: directory not found for option’

You need to do this:

1. Click on your project (targets)
2. Click on Build Settings

• if your error includes the -L flag, then delete the values in Library Search Paths
• if your error includes the -F flag, then delete the values in Framework Search Paths

And regarding the second error, sorry i can’t help you out with that one. Hope someone else can help you out.
