If you receive a CocoaPods error such as: ...ruby/2.6.0/gems/ffi-1.15.5/lib/ffi_c.bundle' (mach-o file, but is an incompatible architecture (have 'arm64', need 'x86_64')), This means you have ffi built for arm64 but not x86_64 architecture. Make sure you have Developer Mode enabled on your iOS device: Settings → Privacy → Developer mode → on Then, do the following:

(1) Install llvm:

arch -arm64 brew install llvm
export LDFLAGS="-L/opt/homebrew/opt/llvm/lib"
export CPPFLAGS="-I/opt/homebrew/opt/llvm/include"

(2) Uninstall ffi:

sudo gem uninstall ffi

(3) If prompted, uninstall ALL versions. install ffi gem for x86_64:

sudo arch -x86_64 gem install ffi`
