Today I updated to Beta 3 of iOS and OSX. After that I got some compile errors:

• Syntax changes
• API changes
• Strange error belonging cocoapods

 Error after update

/[PATH_TO_PROJECT]/all-product-headers.yaml:4:13: error: Could not find closing ]!
  'roots': [
            ^
fatal error: invalid virtual filesystem overlay file '/[PATH_TO_PROJECT]/all-product-headers.yaml'
1 error generated.

How to fix

1. Navigate in Finder to /[PATH_TO_PROJECT]/all-product-headers.yaml
2. Replace the content with the next code block
3. Lock the file by the file information dialog (afterwards the file should look like the image)
4. Ignore compile errors in pod projects

Locked File

{
  'version': 0,
  'case-sensitive': 'false',
  'roots': [
  ]
}
