Answer 1

How I resolved this issue:

1. I exit Xcode then opened my project's .xcworkspace again.

2. While Xcode was starting...i saw warnings...xcode is smarter enough and ask you switch to recommended settings...Tap it and let him do the changes. (Read warning seriously and with positive mind and then you will resolve it)

Answer 4

This issue was connected to "Link Binary With Libraries". I've renamed the target, and there were two .framework files for the Pods. Thus, after removing the outdated one - the issue was solved.

If you just installed/ uninstalled a pod you might want to look at this. Here's what worked for me:

1. First make sure you are opening the .xcworkspace file not the .xcodeproj. But this is probable not what's causing the issue.

2. Delete the pod that was recently just installed.

3. In the project directory on Xcode, open the frameworks folder and if the pod which was just removed is still listed there as one recentlyremovedpod.framework, delete it from there also. This step is what made my project compile eventually.
