I have just gotten the new device around 2 weeks ago.

As a mobile developer, I try to compile my Xcode project after installing Cocoapods with sudo gem install cocoapods to the device.

To my surprise, pod install does not work as expected this time.

Errors

I ended up seeing something as such

LoadError — dlopen(/Library/Ruby/Gems/2.6.0/gems/ffi-1.15.0/lib/ffi_c.bundle, 0x0009): missing compatible arch in /Library/Ruby/Gems/2.6.0/gems/ffi-1.15.0/lib/ffi_c.bundle — /Library/Ruby/Gems/2.6.0/gems/ffi-1.15.0/lib/ffi_c.bundle

Solutions Available:

I have found 3 solutions through the internet so far.

1. Open your Terminal under Rosetta and run sudo gem install ffi in terminal.

Open Finder > Applications > Utilities > Terminal > Right Click > Get Info > Open Using Rosetta

2. Run these lines
sudo arch -x86_64 gem install ffi
arch -x86_64 pod install.

3. Install Cocoapods with Homebrew.

My Pick

I tested out for option 2 as I’m not too familiar with Rosetta at first.

It works.

I eventually decided to give option 3 a try ,which is to install Cocoapods from Homebrew.

Why?

As more and more developer tools start to support M1 natively, I would go for a native option, unless there isn’t any better option.

As it turns out, Apple Silicon (Big Sur) is supported with stable version!

Finale

In my opinion, option 3 is the cleanest solution thus far!

It works perfectly fine.

Happy exploring!
