Errors in Kivy.org documentation: iOS Prerequisites

[HeRo002]

Hi!

This Kivy-iOS install guide: https://kivy.org/doc/stable/guide/packaging-ios-prerequisites.html

Contains these 3 commands, but 2 of them are erroneous, at least on my brand new install of MacOS Sequoia 15.0.1 (on a MacBook Pro from Mid 2012):

$ brew install autoconf automake libtool pkg-config
$ brew link libtool
$ pip install Cython==3.0.0

1. When I run "brew link libtool" I get this warning:

(venv) henrikroseno@MBPtilhdeHenrik ~ % brew link libtool
Warning: Already linked: /usr/local/Cellar/libtool/2.5.3
To relink, run:
brew unlink libtool && brew link libtool

2. When I run "pip install Cython==3.0.0" I get this error, and I have to reinstall version 0.29.36:

(venv) henrikroseno@MBPtilhdeHenrik ~ % pip install Cython==3.0.0

ERROR: pip's dependency resolver does not currently take into account all the packages that are installed. This behaviour is the source of the following dependency conflicts.
kivy-ios 2024.3.17 requires Cython==0.29.36, but you have cython 3.0.0 which is incompatible.
Successfully installed Cython-3.0.0

It's also quite confusing that these 2 install guides differ quite a lot from each other:

1. https://kivy.org/doc/stable/guide/packaging-ios-prerequisites.html

2. https://github.com/kivy/kivy-ios/

Versions

• Python : 3.9.6
• MacOS version : Sequoia 15.0.1
• XCode Version : 16
• Cython version : (( 0.29.36 ))

I'm running into this as well. Pillow-11.0.0 will fail to build against cython==0.29.36. It must be 3.0.0.
