Wrong iOS SDK?

[Hillen Richard]

Hello list,

after using livecode for standalones on OS X now  I want to make my first iOS Compilation using livecode 6.7.8 or 7.1.1.

My Xode ist version 7.2.1.

In Livecode/Preferences/Mobile Support the list of development SDKs is empty.
If I try to add an entry choosing my XCode I get the answer, that it is not a valid iOS SDK among 5.1, 6.1, ...9.1.

What am I doing wrong?

Thank you in advance,
Richard.
