To Reproduce
Steps to reproduce the behavior:

1. run flutter run
2. got stuck on Running pod install...
3. cd ios/
4. run pod install got stuck on Installing gRPC-Core (1.28.0)

Hi @yuriGett
Not able to reproduce this issue on pod version 1.9.1
Can you please try same packages in a new project?
Thank you

[yuriGett]

Hi @TahaTesser just tried on a new project and facing the same issue..

[greenblue467]

same here, any solution?

[devr-tech]

any solutions?

[greenblue467]

After couple hours of pod installation, it finally worked. I guess we have to be very very patient...

[yuriGett]

My solution was to download the Pod gRPC-Core from another project on Github and manually to add it to my Pods directory and then to run pod upgrade and pod install in ios directory

[KrystofM]

the cloning of the repositories when installing gRCP-Core seems to be endless but when running the Pod install verbose it is actually getting somewhere. This really is dependency hell.

Okay got it to work by downgrading to an older version and now being able to build. But I am getting build times like 210.6s or 218.6s! This is seriously very bad.

[iTatla1]

Facing same issue. @KrystofM which version did you use.

[emran92]

I was having the same issue on a new project. But after getting stuck on gRPC-Core install I waited around 5-10 minutes and then it proceed with pod install. Probably it's a server issue.

[iTatla1]

I've waited and still am waiting it's been more than half an hour its still stuck on Run POD

[iTatla1]

IT WORKED LOL. BUT IT ONLY TOOK 69.7 MINUTES :D

Imagine 1hr and 9 minutes for a single POD install. They need to fix it!!

[danahartweg]

I had a similar issue where pod install would fail on gRPC-C++ because it couldn't include openssl. Adding the below to the Podfile to manually lock the version of BoringSSL_GRPC seemed to fix things up for me for the time being. Having other issues building right now, so if it turns out everything crashes and burns when running in-app, I'll amend this.

# lock the version of `BoringSSL-GRPC` so installing gRPC-C++ via cloud_firestore doesn't fail
pod 'BoringSSL-GRPC', '0.0.3'

This issue led me in the right direction: grpc/grpc#16821

[hashanspc]

I had the same issue and this article helped.
Also be patient in the pod install as it could take like 15mins or more sometimes when you come across this issue.

Hey all, as part of our on-going work for #2582, the project structure/setup for iOS & MacOS in our Firebase Firestore rework (#2913) has been improved which should help with this along with using the new pre-compiled Firestore binaries to improve build times.

The rework has now been merged into master. We'll look at publishing some prereleases in the next few days. Thank you
