Xcode Template for Pythonista

[mrcoxall]

I am trying to upload a Pythonista project to the Apple App Store.
I have tried many, many time and keep getting code signing errors.
I am using Xcode 8.2.1
So this is what I have done:

Started with new Xcode Swift single view project, archived it and was able to submit it to the App Store. So my certificates are all working. I downloaded the Xcode template and then archived it. When I submit to Apple, it hangs on the code signing for a really long time and then comes back with this error:

ERROR ITMS-90035: "Invalid Signature. Code object is not signed at all. Make sure you have signed your application with a distribution certificate, not an ad hoc certificate or a development certificate. Verify that the code signing settings in Xcode are correct at the target level (which override any values at the project level). Additionally, make sure the bundle you are uploading was built using a Release target in Xcode, not a Simulator target. If you are certain your code signing settings are correct, choose "Clean All" in Xcode, delete the "build" directory in the Finder, and rebuild your release target. For more information, please consult https://developer.apple.com/library/ios/documentation/Security/Conceptual/CodeSigningGuide/Introduction/Introduction.html"

The only thing I can figure out is that it seems to be trying to code sign the PythonistaKit.framework and does not seem to be able to. I can see "PythonistaKit.framework (0 Entitlements), just before I validate it.

Wondering if anyone else is able to reproduce this error, or even better have a fix to the problem.
Thanks

@RomSpy Yes, that's something I'd really like to do soon, and I've already done some of the work required, but it's still kind of a mess.

Is there an up-to-date summary of the idea for packaging up a Pythonista project to make an app? I see that the template linked from

https://forum.omz-software.com/topic/1911/new-xcode-template-beta

doesn't exist anymore, and I'm not sure where to begin learning.

@sreyemnayr I tried your re-worked script and it worked well.
I used #import pythonista\n rather than #\input texinfo\n
To make it run faster I prepend 10 strings in each iteration, e.g.f.write("#import pythonista\n" * 10 + source) and set counter to increment by 10.

Hello everyone,

Here is a reworked script that adds the comments at the top but preservers coding= comments.
It is not perfect, but it helped me succesfully submit an app to the Appstore, I hope it is of help to every one.

#import pythonista
# Change the ********** to point to the directory containing the Pythonista framework :
project_path = '**********/PythonistaAppTemplate'
pylib_path1 = '%s/PythonistaKit.framework/pylib' % project_path
pylib_path2 = '%s/PythonistaKit.framework/pylib_ext' % project_path
MAX_REPEATS = 10

import shutil
import os
import subprocess

def check_is_executable(file_path):
    file_output = subprocess.check_output(['file', file_path])
    if 'executable' in file_output:
        return True, file_output
    return False, file_output

def fix_executable(file_path, dry_run=False):
    with open(file_path, 'r') as f:
        source = f.readlines()
        if 'coding:' in source[0].lower():
            firstline = source[0]
            start = 1
        else:
            firstline = ''
            start = 0
    if dry_run:
        if firstline:
            print(firstline)
    else:
        with open(file_path, 'w') as f:
            f.write(firstline + '#import pythonista\n' * MAX_REPEATS + ''.join(source[start:]))
    is_executable, out = check_is_executable(file_path)
    return not is_executable

def fix_pylib(pylib_path, dry_run=False):
    print ("fixing", pylib_path)
    for path, dirs, files in os.walk(pylib_path):
        print(path, dirs, files)
        for filename in files:
            full_path = full_path = os.path.join(path, filename)
            is_executable, file_output = check_is_executable(full_path)
            if is_executable:
                extension = os.path.splitext(full_path)[1].lower()
                if extension in ['.py', '.pym'] or filename == 'command_template':
                    if dry_run:
                        print '### Executable found: %s' % (filename,)
                        fixed = fix_executable(full_path, dry_run)
                    else:
                        print 'Fixing %s...' % (filename,)
                        fixed = False
                        counter = 0
                        while not fixed:
                            fixed = fix_executable(full_path)
                            counter += MAX_REPEATS

                        print 'Fixed with '+str(counter)+' dummy lines.'
                else:
                    print '### Executable found, but does not seem to be Python code: %s' % (full_path,)

if __name__ == '__main__':
    fix_pylib(pylib_path1, False)
    fix_pylib(pylib_path2, False)

so, this may be a stupid question, but my understanding of this problem is that file is running locally, and is getting rejected locally.

so, why not just edit /usr/share/file/magic (or copy it, edit it, then file -C to compile it to a new .mgc), or create an alias to file with a -m argument pointing to your custom magic file. It should be possible to edit the entry for pythonm or add custom search for the shebang or coding lines, to simply output a safe mimetype,

[amdescombes]

Hi Jon,

I think that is a very good question and a very interesting option to explore as it would avoid modifying the framework. I'll look into it as soon as I get a chance and report my findings back.

Cheers

I really want to have a new Xcode template for Pythonista 3. I realize that I've already bought Pythonista so I'm not generating new income for @omz.... so I hereby pledge to send money via Paypal/Zelle (or any other method) to @omz to help support his time for the production of a new Xcode template. I'd gladly pay $25 for a new template. I'd even pay this annually if it would be updated regularly.

Thoughts anyone? @omz?? How can we help get a new Xcode template made?

[vignesh]

@TheRealBret Good news!
@omz said:

Here's a first attempt at a Python 3-based Xcode template: https://www.dropbox.com/s/5l94m0xjbot5je0/Pythonista3AppTemplate.zip?dl=1

This is roughly equivalent to the current App Store version (not the 3.3 beta), and not final, just something to play around with for people interested in the Xcode template. Let me know if anything's unclear.

[TheRealBret]

Indeed - I’m very happy to see the new template. Thank you!

My offer still stands - I would like a way to give a donation to @omz to help offset continued development of Pythonista. I can’t see how my payment a year ago is helping today.

[vignesh]

Is it possible for someone to upload a version of the template for python3 with the fix to include the line at the top of all the files already done? I am having lots of trouble doing it myself.
