Swift cocoa pods issue: '/Library/Ruby/Gems/2.6.0/gems/ffi-1.15.5/lib/ffi_c.bundle' (mach-o file, but is an incompatible architecture...'

Question

Is there a way to implement Amazon Polly into Swift?

I followed this iOS-Example, that is given by Amazon Polly: https://docs.aws.amazon.com/polly/latest/dg/examples-ios.html

The problem is: I receive an error when trying to install the pod file.

My pod file looks like this:

platform :ios, '15.0'
use_frameworks!

target 'PollySample' do
  pod 'AWSMobileClient'
  pod 'AWSPolly'
end

When I do pod install, I receive the following error:

Searching for inspections failed: undefined method `map' for nil:NilClass

Can I just use a simple API Call or something similar without cocoapods?

Answer 1

I found the solution to this question. The problem was not AWSPolly, but some compatibility issues.

I found something that works here:

https://github.com/CocoaPods/CocoaPods/issues/10220#issuecomment-730963835

sudo arch -x86_64 gem install ffi

Then

arch -x86_64 pod install

Thanks to your comment @matt. It helped me.

Also keep in mind as matt suggests:

But this is still not right. If you have to say sudo you are doing it wrong. Install your own Ruby.
