title: Is there a way to build and run .xcodeproj file from zipped project?
body: <p>I have an old project that already published on the Appstore a while ago, which is not compatible with the recent iOS 11. Now I want to submit an update to make my App available on the Appstore again, but for some reason I can not find the Xcode project on my computer. The only thing I found on my computer is the zipped project, which I can browse its contents, but there is no "xcodeproj" file within it, and the nib files are not openable as I'm getting "Interface Builder cannot open compiled nibs." error every time I double click on them. Is there a way to rebuild and run my project? instead of starting my project from scratch. Any help will be appreciated. Thanks in advance.</p>
  
  <p>Update: I have this black icon with "exec" within the zipped file, which has no extension, but when I open it with Xcode I get a window with this black image in it, is it the .xcodeproj file?</p>
