I installed fltk just moments before.

I think I know why this may have failed. If you look at the pypi
download files here
https://pypi.org/project/pyFltk/#files
you will see that we only have a built package for Python 3.9 on arm64
based macs. So issuing "pip3 install pyfltk" downloaded the source
package instead since you probably have a different version of python.
In this case, you will need to build it yourself from source or
install python 3.9 with "brew install python@3.9". Here are the
instructions to build it from source.

brew install fltk
brew install python-setuptools
brew install swig
pip3 install wheel
Download the source from
https://sourceforge.net/projects/pyfltk/files/pyfltk/pyFltk-1.3.9/pyFltk-1.3.9.tar.gz
tar -xzf pyFltk-1.3.9.tar.gz
cd pyFltk-1.3.9/
python3 setup.py swig
python3 setup.py build
python3 setup.py bdist_wheel
cd dist
pip3 install pyFltk-1.3.9-.....whl

Let me know if this works for you. When I am able to get my hands on a
mac, then I will upload more pre-built packages.

Unfortunately that did not work for me. I got the install, opened it up, and then build failed.

Do you have swig installed? To build from the source distribution you will need swig, once that is installed, please try:
python3 setup.py swig build

If this does not solve your problem, please show the swig version you are using and the output of:
python3 setup.py swig

If you would like to refer to this comment somewhere else in this project, copy and paste the following link:

brew list shows swig as installed (I installed it as I followed your steps line by line so its the newest version as well). python3 setup.py swig build gives the following:

Could you please show the output of:
swig -version

Ok, I think I know what your problem is. It seems that the changes for swig V4.2 did not actually make it into the tarball of pyFltk1.3.9. Either you have to install swig V4.1 or older or you have to get the pyFltk sources from sf.net. Sorry about that, we will try to create a new tarball as son as possible, but this will definitely take a few days.
