4 years ago Okay,
I figured out what is the cause and how to solve it.
when you enter pod install it will try to connect to a repository and fetch some data specs and for some reason that repository is not available or it sneds the wrong response format and this will cause the failure.
how to solve it? after a day googling about it, I found the answer here https://github.com/CocoaPods/CocoaPods/issues/9303
since that repository doesn't work, your pod install will fail.
but there is a solution, all of those specs are available under a git repository.
by adding the following line to your Podfile
source 'https://github.com/CocoaPods/Specs.git'
this will tell the pod to use that git repository instead of the pod default repo and that will clone the repository(which is about 800MB) into your system and the will use that. this solved the issue. It's better to mention this in development documentation where it's just mention to run commands.

pod installinside ios directory, It fails with below information. on MacOS mojave.Based on the Error, I find out this needs to have Flutter installed? why this needs flutter? I installed flutter and still fails.
