How to build for iOS

[bsauvage]

After searching around I found some fractional info on how to do this.
Hitting some roadblocks and would like some help to go through it, so that I can compile the procedure within this thread and help other people who want t do the same.

Steps below.

0/ get an apple developper certificate by following the procedure in https://developer.apple.com/register/index.action
[question: is this really needed to build for oneself? I found no way around so ended up doing it, but if somebody knows better please advise]

1/ follow instructions in the page: https://github.com/hrydgard/ppsspp/tree/master/ios
[unfortunately hitting compile critical issues, even after adding the dev certificate to Xcode. Build fails with the below log -> can somebody please help and tell me what's missing/what I'm doing wrong?]
