Please, gues,
I do not get it. I will create beta versions for some testers (extern) but I do not know how. Where should I add the UID’s and which file should i send to them
hope you can help me!
with best regrads
You need to create a device ID (on Apple’s iPhone developer portal page) for each tester’s device. You then add those devices to the developer provisioning profile for your app and download the updated profile. Replace the existing profile in Xcode and build the app again. Your testers should then be able to use the app for testing purposes.
so i send them the app (folder?) and the provision or without this provision file? thanks in advanced!
You certainly need to send the app. I’m not sure if the provisioning file is actually necessary. They are very small files, so it wouldn’t harm to attach them just in case 
Yyyy not working 
I added the UIDs on the webside and I have generated a prowision (after that I downloaded and added the profile to my xcode). after building and sending the *.app file(it is in the player/build folder) to the beta tester he got a error coping the app folder to itunes. why? is there an detailed tutorial what to do? please help
