An example of converting an older python.Framework Xcode project to compile in Xcode 6

00 - Converting older Python.framework Xcode projects for Xcode 6.md

When Apple moved to Xcode 5 (and later 6), they changed how you embed the Python.framework in a project: https://developer.apple.com/library/mac/technotes/tn2328/_index.html

This is a basic walkthrough of the process of conversion per that documentation for Xcode 6.

The example used here is the latest version of grahamgilbert's Crypt (at the time of this writeup): https://github.com/grahamgilbert/Crypt/tree/bdd49c849ed07fbc86d8c6f5bc31a525061d5077

(If you're viewing this via a gist blogging platform like roughdraft.io, make sure to view the original gist as there are image files included within the steps)

01 - Project Navigator View.png

01 - Project Navigator View.txt

Open the project and make sure you're in the Project navigator view (folder icon).

02 - Select the Project.png

02 - Select the Project.txt

Make sure you're looking at the Project settings on the right.

03 - Select Build Settings Section.png

03 - Select Build Settings Section.txt

Select the Build Settings section.

04 - Change the SDK.png

04 - Change the SDK.txt

Change the Base SDK to 10.9. Xcode 6 does not ship with 10.8 or earlier SDK.

You can build 10.8+ targeted projects against the 10.9 SDK.

Alternatively, for 10.8's SDK specifically, check out:

05 - Remove generic Python framework header search path.png

05 - Remove generic Python framework header search path.txt

Double-click on the setting for Header Search Paths.

This will give you access to the multi-entry editor.

Use delete/the minus button to remove the old Python framework entry.

06 - Add specific Python framework header search path.png

06 - Add specific Python framework header search path.txt

Follow the instructions at the Apple documentation linked at the top.

Specifically the section: "Listing 1: Getting compiler flags"

If you're doing it right, the path you get should be:

/System/Library/Frameworks/Python.framework/Versions/2.7/include/python2.7

Use the plus button to add this path as the last entry for header search paths.

(You can drag the order after adding them, make sure it's last)

07 - Edit main.m to reference Python.h directly.png

07 - Edit main.m to reference Python.h directly.txt

Find references in your project for the 'Python.h' header file.

Since this is primarily a pyObjC application project, that means the 'main.m' file.

Change the references from: <Python/Python.h>

To: <Python.h>

08 - Remove reference to Python framework.png

08 - Remove reference to Python framework.txt

Right-click on the Python.framework and delete it.

09 - Drag and drop in libpython.dylib.png

09 - Drag and drop in libpython.dylib.txt

Again, following the instructions from Apple above, look at:

"Listing 2: Getting linker flags"

Following the instructions, it should give you the path:

/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/config

Open that location in the Finder and look for the 'libpython2.7.dylib' file.

Drag it into the Frameworks section of the project in Xcode.

When the dialog prompts, make sure 'Copy' is *unchecked*.

Congrats, you're done!

I set all this up with python, but how do I know add as well a python library? And how do I call it then?
