I have found a solution to this:
(0. it is always necessary to push your newest .git to the remote repo in order for bitrise to recognize the newest changes)...this alone did not help tough...
Here are the steps that did help:
- delete all your pods-folders, podfile.lock-file and also your myproject.xcworkspace file
- pod install again..
- re-open your newly created xcworkspace file
- inside Xcode, go to "Edit Schemes"--> Manage-Schemes (right click run-button to find it)
- delete all your existing Schemes (all of them, also the pods ones...)
- inside Scheme-manager - press the Plus button
- add your project
(if there add your WatchKit or other extension Schemes)
for all newly added Schemes, press the "share" tag
- commit these changes in git and push to your repo
--> after these 10 steps, the previous error in bitrise does not show up anymore...
