Xcode – change xcrun developer path

1. Go to Targets in Xcode.
2. Build Settings on your project's target (your current development name).
3. Search for Product Name under Packaging. Change its value to what you want your new project name to be.

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.
