How to rebuild development pod changes?

I had the same issue with Xcode 10.0 (10A255). Changing back to the legacy build system (in File -> Project/Workspace Settings) worked for me to resolve the issue for now, until this is fixed by either Cocoapds or Xcode.

As a workaround I've been manually "cleaning" out my development pods.

1. In the Pods project open Products select the development pod framework(s)
2. In the inspector on the right I select the arrow which opens Finder
3. Delete the framework(s)
4. Build/Run

Hope that helps, and that Apple fixes this soon...

P.S. Will definitely be writing a simple script to do this.

Also seems like sometimes I must delete the Intermediate build(s) as well.

Looks like it was fixed in CocoaPods 1.8.0 (Wow, it been a whole year...)

While Changing back to the legacy build system works, the build time might increase in some large projects. An alternate solution is to add this run script find "${SRCROOT}/Pods" -type f -name *frameworks.sh -exec bash -c "touch \"{}\"" \; to touch all framework scripts under your project's Build Phases->Embed Pods Framework. This should pickup your new changes until this bug is fixed.

I'm using to below.
