the debugger has exited status 0.

this isn't solution, @ least backtrace see if can see it's dying.

build , debug app , run app until error. in console (where sigabrt error appears) type

bt 

and return key. if you're fortunate tell failed. you're looking highest (earliest written console) file , line number, 1 of view controllers, .m file.
