Solved: macOS Sierra, Xcode 8, missing quicktime.h

Fresh OS install. Xcode 8. macOS Sierra.

Trying to build the “again” example under Xcode and getting a “QuickTime/QuickTime.h file not found” message. Anyone have this working?

Solution from blegoff
Set the base SDK version for the project > and > for each target.


Yes, it seems that Quicktime and QTKit APIs are now deprecated in Sierra, so the error you get is normal.

A workaround is to use the macOS 10.11 SDK, that you can download here.
Place the “MacOSX10.11.sdk” folder in /Applications/
And set the Base SDK to “OS X 10.11” for the again target in the Xcode project settings.


It’s great advice, but as you can see from the screenshot it has not worked. Am I doing something wrong?

That’s because you have to set the Base SDK for the again target.
You did it, but for the again project. :wink:

You called it.

It is fully working now. Thank you so much for the help.
