Xcode Template for Pythonista
polymerchm last edited by
@omz Based on my experiments, am I correct in assuming that the template only has the 2.7 interpretor? Any hope the the 3.5/3.6 template will be forthcoming? I am learning swift just in case.
@omz I tried as you suggest and used the Application Loader. Same problem happening. Still getting code signing errors. Have tried using "Auto code signing" and even old school downloading the certificate myself and still getting the same messages.
Have you been able to get anything uploaded to the App Store?
Do you have a template that I could try?
Wondering if anyone has been able to submit an app successfully since Jan 1, 2017.
I still am getting signing errors and have no workaround that will work.
I have app waiting to get approved and need a solution.
Have you tried the recommendations here?

I know this is an older thread, but I just wanted to confirm that with the texinfo fix, I have successfully submitted and had an app approved in the last few days.
So the fix is required to get past the automatic filter, but submission is OK with the workaround.

@omz Getting back to the question of @polymerchm : Is it possible to run python3 in Xcode? Using a she-bang line like "#! python3" does not work. sys.version still returns "2.7.5 (default, Feb 15 2016, 15:15:36)". Thanks!

@marcus67 It's currently not possible, I'm afraid.
@omz Thanks for getting back to me.
I was wondering if there is any explanation on why it is no longer possible?
I used Pythonista last year with my grade 11 programming course and got over a dozen apps published on the App Store. I have just started using it again with this years group and told them we will be doing the same thing. If there is anything I can do to help the process along, please let me know. We will not be starting to write the final apps until December.
This post is deleted!
@JonB The texinfo trick continues to work. Had an app accepted just last week.

Would it be possible to create a repo or a page on Pythonista-Tools that could be a FAQ for using the template? It seems like there are several prereqs and then several steps to complete the process and it would be great to have a landing page for sharing all that tribal knowledge.
I spoke too soon. I had to upgrade Xcode because of iOS11 compatibility, and now I'm back to getting the code signing errors for all the .py files, even if they have the texinfo header. Building apps for local distribution works fine, I just can't sign the code as part of the validation process for the App Store.

Looks like the texinfo hack needs to be modified. The code signing process uses file(1) to check the type of file in the package, and file(1) identifies executable code by checking against different file types and scoring each file type. Apple modified the matching "magic" for python to look for python keywords like "def", "import", "try", "except", etc and each use gives a higher score to python. So for the tex info hack to work, it needs to occur more frequently than the python keywords. Some files just need a single texinfo line; other files need 400+ copies of the texinfo line (some of the python checks only examine the first 4096 characters of the file). Its easy to modify the script above to accomplish this, but hardly elegant.
Hopefully somebody will find this useful and find a simple fix.... like perhaps there's another file type that short-circuits the checking magic? Also, the Apple developer documentation say that script files could go into a specially named subfolder, which would be much simpler, but I've haven't gotten this to work.
out of curiosity, is
fileused locally, or on the server?
Couldn't you use th older file version for identifying text files?

Yes, It's locally.
You can replace older version of 'usr/bin/file' and 'usr/share/file' to fix it, if your mac os version has updated to 10.13.
Thanks. Will give it a try and test an upload to TestFlight too.

Here's the re-worked script, which throws as many of those dummies at the top of each file as it needs to stop the madness.
EDIT: There are some problems with this method as well, as it bounces the lines indicating the encoding style, which breaks a bunch of stuff... I ended up having to regex replace them back to the top, but will work this script out to do it better later. Just be aware that this will happen!

Hi @sreyemnayr, just tried your script, but still getting an error on upload to app store. Any other ideas or refinements to your script?

I'm making a bit of progress:
- My original error related to the future.py file in pylib, after running the script the Xcode error changed.
- I noticed that after running the above script the specific file that I was getting the 'Invalid Signature' error on had change to pylib/compiler/init.py. I had a look at that file and it didn't have a #\input texinfo up the top so I added it manually.
- I then reran the script and the error changed to pylib/compiler/ast.py This did have lots of #\input texinfo, so I copy and pasted all of them to double the amount of #\input texinfo lines at the top of the file. This seemed to satisfy Xcode.
- I then reran the script and the error changed one of the files in pylib/ctypes/test. I just deleted the whole pylib/ctypes/test folder.
- I than reran the script and the error changed to pylib/dateutil/READEME. I deleted the README file and the NEWS file while I was at it.
- I than reran the script and the error changes to pylib/site-packages/dropbox/init.py. As I'm not using dropbox in my app I just deleted the dropbox folder.
- I then had errors on pylib/site-packages/twitter.py, webbrowser.py, xmltodict.py and ui.py. They all had just one #\input texinfo line so I inserted an extra 1000 #\input texinfo lines at the top of each.
- I then had remaining errors in the files in pylib_ext/ so I added about #\input texinfo lines at the top of each.
- Finally my app submitted successfully!!!!
I must confess I really don't understand all of this. Feels like there's got to be a better way....
Thanks to @sreyemnayr for posting the script as I would not have solved this without it.
