Building iOS app on HighSierra. Installing requirements fails.

I installed MacPorts and installed python 3.6 with Macports. I also installed all the dependencies. When trying to run the makefile, I get the following failure:

MacBook-Pro:ios kevin$ ./make_ios_project.sh

Any help would be appreciated. I’m wishing to compile this from source to ensure that my development setup works. Then my plan is to switch to the SLP version of Electron cash to try to add some of the SLP features to that version of the mobile wallet. As an aside, I was able to successfully compile the Electron Cash SLP, OSX version from source on my setup. However, I was using homebrew and not Macports.

All of the electron cashes have for at least the last year refused to spend UTXOs containing tokens in them. This includes the iOS version.

Ah! There are always warning with SLP to not send them to non-SLP wallets…and the standard Electron Cash wallet is never listed in the “safe list”…at least in a way that I’ve remembered it.
