This post will show you how to fix this error.
error: There is no SDK with the name or path ‘iphoneos…’
This error means that the SDK you once ran your program in has been replaced by a new sdk.
In the file menu click projects, scroll down to edit project settings, and click on it.
Under architecture there should be a column that says base SDK.
Change the base SDK to the highest iOS device. Now you have fixed you error.
