xcode8 - xcodebuild wank with signing ipa

https://pewpewthespells.com/blog/migrating_code_signing.html#signing-in-xcode-8

error looks like:
None of the valid provisioning profiles allowed the specified entitlements: application-identifier, beta-reports-active, keychain-access-groups

voodoo fix:
after using xcode (instead of the command line) to archive then export an ad-hoc ipa, the command line build issue seemed to resolve itself.

# the result may contain A-Z, a-z, 0-9, “-” and “_”. “=” is also used if padding is true.

# In the block form, the current match string is passed in as a parameter, and

command line rename utility

install with homebrew:

[smr@smr ~]$ brew install rename

examples

rename -N ...01 -X -e '$_ = "File-$N"' *



specify 0-padding of a given width:

rename --dry-run -N 001 -e '$_ = "$N-$_"' *



specify a certain starting number:

rename --dry-run -N 007 -e '$_ = "$N-$_"' *



prepend:

rename --dry-run -A "500"- *

rename --dry-run -N 001 -A 'xxxx' *



rename to incrementally numbered files:

rename -N ...01 -X -e '$_ = "File-$N"' *



This will throw away all the existing filenames and simply number the files from 1 through however many files there are – except that it will preserve their extensions.



perl-like replacement (delete spaces)

rename --dry-run 's/ //g' -c *

rename s/jpeg/jpg/ *



[smr@macpro e-pix]$ rename s/jpeg/jpg/ *

[smr@macpro e-pix]$ ll
