Difference Between includes and imports
header-files, include, include-guards, ios, objective-c
Solution
The `#import` directive is an improved version of `#include`. `#import` ensures that a file is only ever included once so that you never have a problem with recursive includes.
`#import ""` first check the header in project folder then goes to system library, and the `#import<>` checks for system headers". In theory the locations are compiler defined and they could be implemented differently on a given platform.
