Why am I getting ibtool failed with exit code 255?

Question

All of a sudden I can\'t build my project. I get the following compiler error:

/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.pl

Answer 1

I figure out that if you use Xcode for too long without closing it, Xcode will become ultimately unhelpful and giving you random mystery error. so i regularly restart Xcode and all the apps that I`m running on my mac every time a suspicious error appear.

Xcode Cache
1st try check all your segue/outlet/storyboard controller class. sometime storyboard would disconnected with the view controller class that has been set. (this might cause run time error).

2nd try cleaning up you project and goto (~/Library/Developer/Xcode/DerivedData) and delete your project cache. then Force Close Xcode then restart it.

3rd try check all your segue/outlet/storyboard controller class. sometime storyboard would disconnected with the view controller class that has been set. (this might cause run time error).

4th try check (copy bundle resource, compile source - Project > Build phase) make sure the file listed is exist with the correct address and folder. sometime creating a group would cause a folder to be create and causing the file cant be found by the compiler

5th this also might been cause by moved file + Xcode become ultimately unhelpful and giving you random mystery error. and dint update the (copy bundle resource, compile source - Project > Build phase) after the file has change directory

Personal Mistake. unintended deleting
this also might have been cause by calling an deleted ViewController or outlet
