thanks erel..
currently i have hosted builder, but when i use this i must have iOS developer account, it's correct??
and can i debug app when i use hosted builder??
xcode-select: error: unable to get active developer directory, use `sudo xcode-select --switch path/to/Xcode.app` to set one (or see `man xcode-select`)
If you execute Xcode directly does it start up? In the past I have received the path not found error. This occured after upgrading Xcode and then immediately running b4ibuildserver. What fixed it for me was to run Xcode once and then run b4ibuildserver. (Running Xcode seemed to set up the required path settings.)
