I just started to learn "Xcode". The "Build and Debug" tool is typically a Hammer and an arrow. However as I am going through my tutorials, I tried to build and debug the code I was writing and all of a sudden there was a error detected in the code. The "build and debug" tool changed to a hammer and a spray can. I corrected the error in the code, the tool did not change back to normal. The build and debug process runs fine even with the tool not looking normal. Does anyone know anything about this? Does it matter at all what the tool looks like? It seems to be related to this specific file I am using. If I open a different file, the "build and debug" tool is still the hammer and arrow. I will appreciate your help. Thank you.
