This has been issue has been identified to be related to CocoaPods and is fixed in a more recent version of CocoaPods. It's likely all that is needed to fix this is to update the version of CocoaPods this step uses. https://github.com/CocoaPods/CocoaPods/issues/12012

@godrei any updates on this? This is blocking us from using the new Xcode 15 stacks and we don't want to fall too far behind.

@EBaglieriSkylabs looks like Bitrise recommends adding this code to the Podfile to resolve this issue:

Any updates on this? Looks like Apple is deprecating Xcode 14 stacks in April.

I resolved time ago inserting a script step before "Flutter build" with this content:

#!/usr/bin/env bash
# fail if any commands fails
set -e
# make pipelines' return status equal the last command to exit with a non-zero status, or zero if all commands exit successfully
set -o pipefail
# debug log
set -x

#Cocoapods
export GEM_HOME=$HOME/.gem/ruby/3.2.0
export PATH=$GEM_HOME/bin:$PATH
gem install cocoapods -v 1.14.3 --user-install

This can cause some issue with cocoapods cached packages, so i disabled any kind of cache in the "Flutter Build" block:

I'll close this issue as it doesn't seem to be relevant anymore. We believe an old issue probably has a bunch of context that's no longer relevant, therefore, if the problem still persists, please open a new issue.
