Kivy-ios/buildozer ios hostlibffi compiling issues - no scheme named "libffi-Mac"

[cmdn]

Hello! 

I'm currently trying to compile my app for iOS. I've both used kivy-ios alone and buildozer ios, but no matter what I try I keep getting hung up while it's preparing hostlibffi. If it changes anything, it works perfectly fine using buildozer for android, and runs well.

Xcode version: 7.3.1

Buildozer version: 0.40.dev0

libffi version: 3.2.1

python version (for build): 2 (since kivy-ios doesn't support 3 as far as I know)

Running "buildozer ios debug", "./toolchain.py build python2 kivy", or "./toolchain.py build hostlibffi" all end with the following error (this particular run is from Buildozer):

[INFO    ] Running Shell: /usr/bin/xcodebuild ('IDEBuildOperationMaxNumberOfConcurrentCompileTasks=4', 'ONLY_ACTIVE_ARCH=NO', 'ARCHS=x86_64', 'DSTROOT=/Users/user/Desktop/tempcleaned/.buildozer/ios/platform/kivy-ios/dist/hostlibffi', '-sdk', 'macosx', 'clean', 'build', 'installhdrs', 'install', '-project', 'libffi.xcodeproj', '-scheme', 'libffi-Mac', '-configuration', 'Release') {'_iter': True, '_out_bufsize': 1, '_err_to_out': True}

Buildozer.spec includes:

requirements = python2, kivy, openssl 

(had to add python2 at the beginning to fix another error from toolchain.py, which said a version of python had to be compiled before compiling anything else - requests was manually added in source due to no recipe existing at this moment) 

Recipe order, as listed at the beginning of a buildozer build:

Recipe order is ['freetype', 'hostlibffi', 'libffi', 'sdl2', 'hostpython2', 'sdl2_image', 'sdl2_mixer', 'sdl2_ttf', 'python2', 'ios', 'pyobjus', 'kivy']

Imports in main.py:

kivy, requests, json    # requests is manually included, no recipe exists for kivy-ios 

I've scoured the internet for any information regarding this, but can't find anything pertaining to the libffi-Mac scheme not being found. 

I've run this on two different Macs, one being El Capitan (latest bugfix) and High Sierra (also latest bugfix). All end with the same result. I've tried completely removing everything pertaining to it and retrying, clearing out kivy-ios and buildozer directories and reinstalling, and so on - but I always get stuck here. I've tried working on it for a few hours now, and I've just about tried everything I can think of. Any help is greatly appreciated.

If any more information is needed I'd be happy to provide it.

Thanks!

Also, I think I should mention that using the -list flag as it says to states that there are no schemes.
