How can I get python function output (returned values) in iOS app?

Is there any particular reason? The default is to use pymalloc nowadays, so when I build an extension using an installed Python version, it is built against the 'm' ABI and won't work with the Python embedded by briefcase.

new url for bzip is https://web.archive.org/web/20180624184835/http://www.bzip.org/1.0.6/bzip2-1.0.6.tar.gz

Hi all,
I'm not able to import OpenSSL
using
from OpenSSL import SSL
Is there really this module ?

Hi,

I would like to use Python as a scripting language on Android and iOS, to reuse lots of code. On Android libpython + std lib is no more than 6Mo, but with Python-Apple-Support by default the size for iOS is insanely huge.

Is there a way to build a minimal Python distribution (without openssl, bzip, sqlite, etc) ?
Thanks in advance.

I needed IPv6 support for my project, simply changing --disable-ipv6 to --enable-ipv6 worked fine for me. Perhaps make this the default or configurable?

Hi,

Greetings for the day!

Could you please provide me some documentation to consume it in iOS (objective-C) app? If its already there, please provide me the link.

Thanks & Regards,

Hi,

I am the developer of the iOS app "Electron Cash", which uses rubicon-objc and briefcase. Our app is here and it's out already: https://itunes.apple.com/us/app/electron-cash/id1359700089?ls=1&mt=8

I have you guys to thank for developing these wonderful tools to get the app up and running!

However -- I have come to realize that performance of my app suffers a bit, and would like to be able to include native crypto packages such as pycryptodome.

So -- I have no idea where to begin. I managed to cross-compile pycryptodome and tried to "drop it in" to my project. It fails with OSError on import, unable to open/import the .so files. Is this because it has .so files -- which I think iOS doesn't allow, correct? And I presume .so file importing is turned-off on the libPython.a you guys supply -- right?

I noticed numpy does a few special things to statically build and link to the main executable. This is the strategy I have to adopt, correct?

Any chance I can somehow leverage this Python-Apple-Support system to build Cryptodome and add it to my app_packages?

Any guidance is appreciated! Thanks!

Hi! When I try launch template .xcodeproj with precompiled python binaries, I got these debug output:

It's not clear to me how to add python packages (with compiled components) to your projects (i.e., pip install $something). If I want to use Pandas in an iOS app, how can I go about this?

I was wondering if there are any known issues with using the python iOS frameworks in apps that are approved and are in Apple's app store. I can report that I have successfully gotten to the Testlight stage with Apple with no issues, but I know apple can be restrictive with their final approval process. Are there examples of apps that have gone through final approval, anything to watch out for? Thanks

bzip.org and thus the download for the source package, directs to register.com.
Does anyone has any information on that?

Mono runtime with Python iOS/android/macOS/Windows support, is that possible?

Hi, I downloaded a project by using "Python-3.6-iOS-support.b1" . It can run successfully with those 4 .framework files. But when I substitute them with "Python-3.6-iOS-support.b7" (four .a files in it) , it can build successfully but cannot run. The error messages are as follows:

Perhaps setting MACOSX_DEPLOYMENT_TARGET can help prevent this as suggested in Creating an embeddable Python distribution on OS X.

iOS, watchOS, tvOS all give out "No Such Key" XML

The lib/pythonX.Y directory can be replaced with lib/pythonXY.zip, which drastically reduces the size of the distribution. To further reduce the size needed for the standard library, it's possible to only include the pyc files in the zip file.

The size of lib/python3.5 for a macOS x86_64 distribution:

• as is: 117 MB
• without the test directory: 63 MB
• with only the opt-2.pyc files: 23 MB
• zipped: 9.2 MB

It should be possible to reduce this even more, as the python35.zip included with Windows x86-64 embeddable Python 3.5.2 distribution is only 2.2 MB. Perhaps it's possible to use make_zip.py from the CPython repository that is used to created the Windows embeddable distributions.

For Python 3.5 for example, the test folder is 54MB, which is about 40% of the total distribution size.

Keep getting this error. Seems to be related to this ticket. https://bugs.python.org/issue29057

Commenting the include statement out seems to work.

And on some platforms appletvos.arm64, watchos.arm7k. I'm getting:

I downloaded the iOS pre-built framework. However, I got the error: armv7 missed.

Will there be iPhone7 support on the near horizon?

I think the problem is with the --host option, but I have no idea how to change that line.

Thank you again for your great work.

There seems to be a whole lot of non-runtime type stuff in the frameworks.

E.G. the python/include directory is in there as is lib/pythonx.x/test directory.

I apologize if I missed it, but is there a command/script/makefile target etc. to make a slim runtime-only version of the frameworks?

Thanks, ssteinerX

What I'm doing wrong?

I submitted PR #36 through #39 for this already, but am creating an issue here just for completeness.

The basic idea is hashlib uses a C helper function to query openssl lib for the hash functions provided by it (such as ripemd160). The 1-line change PR I submitted adds the compilation of the C function to the final built libPython.a, so that hashlib can do its magic and provide all hash functions.

Without it, only a very basic set of hash functions are compiled in to libPython.a's modules. With it, you get more hash functions. It's a win/win as far as I can tell. ;)

I tried to submit an app to iTunes connect which contains your Python.framework and I get this error:

Dear developer,

We have discovered one or more issues with your recent delivery for "Reroo – find cheap last minute train tickets". To process your delivery, the following issues must be corrected:

This bundle is invalid - The Info.plist file for /Payload/Reroo.app/Library/Python.framework is missing or could not be read.

Invalid Bundle - The bundle at '/Payload/Reroo.app/Library/Python.framework' does not contain a bundle executable.

Once these issues have been corrected, you can then redeliver the corrected binary.

Hi,

I am having trouble using the Python 2.7 framework on iOS. I copied the framework into the working directory and then linked it with my own framework. I keep getting "No such module" error when I import Python.

I have a bunch of files written in Python and I'd like to access a function within the file. Is there any tutorial I could follow that would show me how to configure and use this framework correctly?

Thanks,
A

download the py2.7 package from here directly
but couldnt build success,miss someother lib?

So I'm not sure if I'm approaching this the wrong way (probably an issue on my end) but basically I've been able to build the Python framework for iOS. In my app I essentially have a Python library that I'd like to integrate with, that library interacts with some native Obj-C code. So after adding the Python.framework to my project. I setup the Framework Search Path to point to $(PROJECT_DIR)/MyApp/Support which is the directory that contains the Python.framework. I've also added it as a Linked Framework/Embedded Binary however once I build my project I get ld: framework not found Python when it attempts to link to the framework, which is unusual because the framework exists in that directory.

Hello. Is there a file where library names (ex. nltk - pure python) can be added so that they are also embedded in the built python framework?

I tried to build and I have this error: tar: Unrecognized archive format tar: Error exit delayed from previous errors. I discovered that http://www.bzip.org/1.0.6/bzip2-1.0.6.tar.gz points to an HTML page, and if I run cat with the tar file, it shows me an HTML page.

I just download the latest release for iOS platform, drag into project and run the hello world.

xcode output:
Could not find platform independent libraries
Could not find platform dependent libraries <exec_prefix>
Consider setting $PYTHONHOME to [:<exec_prefix>]
Fatal Python error: Py_Initialize: unable to load the file system codec
ImportError: No module named 'encodings'

code in ViewController.m:

#import <Python/Python.h>
- (void)viewDidLoad {
    Py_Initialize();
    PyRun_SimpleString("print(\"Hello world!\")");
    Py_Finalize();
}

Frameworks:
...
libsqlite.tbz
libz.tbz

Enviorment:
XCode 8
iOS 9.3

I am probably missing something obvious here, so apologies in advance.

I've run make iOS on two different machines, in the 2.7, 3.5, and 3.6 branches, and in no case does it result in a .framework bundle, or even a Versions folder anywhere within the created directories. The output is extremely verbose, but it certainly appears to have exited successfully; it made some folders and an archive, and closed with exit code 0.

When I first ran it and couldn't find a .framework, I had assumed that I have to make the bundle myself and copy the built files into it, but there are a couple of projects on GitHub that make no such reference to that being a necessary step, despite claiming to use this project to build their actual .framework bundles.

Is there something I'm missing here? How do I actually get a .framework out of this thing, or is that not how this is supposed to work and I've misunderstood what you mean by 'Apple Framework format'? If not, is there something about the output I do get that would help work out what might be going on?

My project use the python 3.6 with numpy , it's run prefect
but when i submit project to AppStore，the App Store Connect feedback that some API is non-public
in libnumpy.a
non-public API about this : ccopy, dcopy, scopy, xerbla, zcopy
how can i fix it

When building a project on a case sensitive filesystem, the Xcode linker was unable to find XZ.framework and BZip2.framework on my machine. As it turns out, the Makefile creates fat binaries and symlinks named "xz" and "bzip2", which are usually equal, since Macs per default ship with a case insensitive filesystem. However, choosing a case sensitive filesystem (doesn't matter if HFS+ or APFS) is possible, and the fix is very simple: Create the fat binaries embedded in the framework as well as the symlinks with respect to case sensitivity.

Regarding the pre built packages, it is sufficient to rename the binaries and recreate the symlinks, I was able to successfully link the frameworks after a simple rename.

I will create a pull request demonstrating the fix for the 3.6 branch.

Hi,

I'm still investigating, but the target numpy-{iOS/macOS} fails on the 3.7 branch at the following point

import zlib

fails because zlib.cpython-35-darwin.so is not included in Python-3.5-macOS-support.b2.tar.gz.

I first reported this issue at beeware/briefcase#20, but this seems to be a better place to report this.

Hi and thank you for your great work
when an exception occurs in python that causes IOS app to crashes how can we handle that?
Thank you again.

master branch readme links point to 3.5.b1, while the latest release is 3.5.b2

I was used this framework in iOS,and can run python file with ".py",but I compile to ".pyc",it show a error:"python: Can't reopen .pyc file".I show the compile python version and python.framework are the same 3.5.4.

How can I solute this probrem?
I run the file like thisPyRun_AnyFile(path, "hello.pyc");

thank you !

The python source is downloaded from https://www.python.org/ftp/python/3.7.0/Python-3.7.0.tgz. This URL no longer exists, causing tar to fail trying to handle the 404 error page as an archive. The current URL should be https://www.python.org/ftp/python/3.7.0/Python-3.7.0a3.tgz, but the applied patches probably need to be changed as well.
The links for the pre-built versions of the framework in the README are also broken.
