I had the same problem, under "Build Settings > Search Path > Framework Search Paths" i had
$(inherited) non-recursive
$(PROJECT_DIR)/My non-recursive
Project/Frameworks non-recursive
i think spaces are breaking the directory path
changing it to $(PROJECT_DIR)/"My Project"/Frameworks
solved my problem..
Take note that My Project
is my project name, Frameworks
is where my GooglePlus.bundle & .framework, in case yours contains spaces, adding quotation marks corrects it.. for example: $(PROJECT_DIR)/"My Project"/"Google Frameworks".
