After looking into the different block and searched over the internet, still not able to find a valid reason for this error. I also tried "pod deintegrate" but that will also not worked for me. After installing pods, I got a warning message(pasted below). It seems, this is the reason for XCConfig error. This may be because my team member using older version of CocoaPods.. [!] The version of CocoaPods used to generate the lockfile (1.6.1) is higher than the version of the current executable (1.5.2). Incompatibility issues may arise. To fix this issue I follow the below steps, maybe this will work for you. 1. Right click on xxx.xcodeproj file and click on "Show Package Contents" 2. Open "project.pbxproj" file in edit mode 3. Search " Pods; " in opened file 4. Change : path = Pods; to name = Pods; NOTE: "path" for the newer version and "name" for the older version. Please let me know if it works for you or
