Is there a way to give the user libs precedence over the arduino ones in EmbedXCode ??Sure, RTFM = Read the Fabulous User Manual, on chapter 4 section 2, now as an e-book.
Hi there, ok ok. It was not so easy 
First the manual was not available until today and second you need an iPad...
I did find one and read TFM now. Sorry for that.
Put SD and SD/utility in EXCLUDE_LIBS and now, it works.
Crazy isnt'it ?
Many thanks for your help and generally for this Xcode Template !
Once I finish my project, I will contribute you can count on me.
