Podspec - Exclude all but a subfolder

Question

I have a structure like this

target_files/
├──target1/
├──target2/
└──target3/

And I want to include only "target2" for example and exclude the other targets. How I write the spec.exclude_files?

I found this example for excluding files, but I can't understand how to write it for whole folders.

spec.exclude_files = '_private/**/*.{h,m}'

Answer 1

spec.source_files = [ 'target_files/**' ]
spec.exclude_files = [ 'target_files/target1/**', 'target_files/target3/**' ]

or for the case you ask about, more simply:

spec.source_files = [ 'target_files/target2/**' ]
