问题
I have recently downloaded new Xcode 11 GM Seed 2 so that i can update my project to support Dark mode. (I am already on MacOS Catalina latest beta version-19A558d).
I have my project(workspace with pods) working 100% fine with Xcode 10.2. When I have started building same project with newly installed Xcode 11 GM Seed 2, It randomly freeze while building with title Building X of Y tasks. It randomly stops building any file at anytime. As per my different observations, It stops building while it is building library from my Pods.
I have already tried cleaning, manually deleting derived data files. Also, i have tried by reinstalling Xcode. Also restarted Mac to give try. All trial get failed. If anyone faced same issue and know the solution, please post here.

I were trying all day hard to solve this issue. Finally issue get resolved.
Actually i tried to build/compile the app via Terminal. Then i found that it got struck/freezed while compiling the files from installed 3rd party libraries from pods. The 3rd party library named SwiftSoup was making problem. Then i removed that pod, and commented out the code related to that. And tried compiling/building the app again. And It worked successfully this time.
UPDATE: I followed @Paul's Answer, that works without removing pod, keeping same pod and code working. Just need to update settings as described by him. But make sure, that you need to change this setting every time you update your pods.
