Distributing Swift iOS applications ad-hoc

Question

I have two empty iOS single view apps compiled to IPA through Xcode 6 beta 2. One is Objective-C, second one is Swift. Both of them have exactly the same code signing settings. When distributing ad hoc with test flight or hockey, Objective-C version installs without a problem. Swift one errors out with 'Unable to download the app the moment'.

I ran iPhone Configuration Utility logs on it and this is what I get :

Jun 24 17:36:27  installd[3555] <Notice>: 0x2c1000 handle_install_for_ls: Install of "/var/mobile/Media/Downloads/-6680582027007079892/1462391056366119034" requested by itunesstored

Anybody has an idea what I might be doing wrong?

Thanks

I found a solution. This seems to be a known issue (17283374) with Xcode 6 beta.

Fix that worked for me is to unpack and re-pack the ipa, stripping the extended attributes that are causing problems:

ditto -xk /path/to/file.ipa /tmp/my_extract_path
ditto -ck --norsrc /tmp/my_extract_path /path/to/new_file.ipa
rm -r /tmp/my_extract_path
