Add support for iOS

[cclauss]

Can we get support on iOS?

pip install psutil on Python 3.7 on iOS Pyto results in...

SystemExit: platform ios is not supported

Would it be possible to support iOS? If it’s possible (it seems some modifications are needed, not sure) I think I would need to compile it and include it in Pyto.

I have an iphone but I don’t know anything about iOS development or Python on iOS. But this is interesting. Some preliminary noob questions:

• how do you install Python on iOS?
• how do you develop for iOS? Specifically: can you emulate it on Linux and setup a working environment?
• assuming this is done, how are you supposed to install psutil on iOS? Via pip? Apple appstore?
• any idea if macOS and iOS kernels are similar? I wonder if macOS implementation can be reused.

https://itunes.apple.com/us/app/pyto-python-ide/id1436650069 is how you install Python on your iPhone. You can edit Python files and run them directly on your iPhone — You don’t need Linux. Pip install is enabled.

[ColdGrub1384]

We use Python C API, so no other process is spawned inside the app.

[ColdGrub1384]

With pip, only pure Python modules can be installed. So if a module has to be compiled, I have to compile it and include it in the app.

@giampaolo Were you able to get Python working on your iPhone?

I was wondering if there was any interest in reviving support for iOS. Since I want to add psutil and bpytop to iOS and macOS. Currently when I try to build psutil for iOS. I get this error.

I was able to successfully build psutil for macOS on both amd64 and arm64. I was hoping since arm64 for macOS and iOS are pretty similar. That clang was able to compile it correctly however it seems that assumption was wrong. I am guessing this means support for iOS needs to be added by the developers of psutil. If this is not case please let me know. I have very little knowledge on python. So I am sorry ahead of time if this is not the case.

Here is the little progress I made for psutil.

I'm using a-Shell on iOS and I cannot install the psutil package (maybe because there is no precompiled wheel for ios?).
This is the error I got:

a-Shell author says that he can solve this issue including the precompiled binaries of psutil into the app as he did for most python libs, but he needs a version of the lib that compiles for iOS, and at the moment psutil doesn't have one.

Please add support for iOS platform.
