2,286 PointsLike force quit Xcode and run it again?
Ryan Jin
15,337 PointsNo, sorry. I mean stop the app you are running in Xcode and run it again. Keyboard shortcut is "Command" + "." and then "Command" + "R". The situation you are facing sometimes start when you start the iOS simulator for the first time after your computer has booted.

2,286 PointsIt's saying build failed.
Ryan Jin
15,337 PointsIt might be your code problem, so you might want to check on that. If there is no problem in your code, then I have no idea why it cannot run.
Ricardo Gonzalez
2,286 PointsWell the error has a red octagon with a white exclamation mark in the middle.
Ryan Jin
15,337 PointsThen it is your code error, if it is an octagon, then you can click on the error and see what the error is. And then fix it.
Ricardo Gonzalez
2,286 PointsSo i think that its just an error within my code but I try looking for it and I can't find no error.
Ricardo Gonzalez
2,286 PointsWell I have tried but I can't seem to fix it.
Ryan Jin
15,337 PointsCan you tell me what's the code you have at that line, maybe I can help you fixing it.
Ricardo Gonzalez
2,286 PointsWell idk which code is the one causing the error but when i click on the error this is what it says "linker command failed with exit code 1 (use -v to see invocation)"
Ryan Jin
15,337 PointsIs the error displayed in the console or beside your code or only on the bar on the top
Ricardo Gonzalez
2,286 PointsThe error is displayed on the top and also the section where you are able to see all errors within your whole project.
Ricardo Gonzalez
2,286 PointsI think it's call the issue navigator.
Ryan Jin
15,337 PointsAre you using OS X El Capitan beta or are you using a not up-to-date Xcode?
Ricardo Gonzalez
2,286 PointsWell it's Xcode version 6.4.

The 'red error octagon' that you described will DEFINITELY prevent you from building your project. The red error means there's some roadblock error that must be fixed before your program can be compiled.
Look through your code - xcode highlights errors.
