Hi @thehaigo, I've fixed iOS build in the main branch, and it should work by setting the following env vars,

export EVISION_PREFER_PRECOMPILED=false
export MIX_TARGET=ios

And the precompiled version (w/ or w/o contrib modules) will be available in v0.1.36 (although you still need to redo the codesign for it).

Please feel free to reopen this issue if this fix doesn't work for you. :)
