Xcode 11 GM Seed 2 freezes while building workspace/project

Question

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.

This might sound weird (as always) but i had similar issue and it turns out it had something to do with disk space. Issue gone when I've freed around 10gb of disk space. — inokey, Sep 20 '19 at 09:22
Another guess -- command line tools version in Xcode settings? — inokey, Sep 20 '19 at 09:25
@inokey : just checked. Command line tools are also of Xcode 11. — Mehul Thakkar, Sep 20 '19 at 09:27

I had to do this on my actual application target, due to extensions on the `Collection` protocol – Des Oct 14 '19 at 12:08

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.

Other option is to turn off optimization in the SwiftSoup build target to work around the infinite loop bug in the Swift optimizer. – Paul Beusterien Sep 24 '19 at 21:12
@PaulBeusterien : I am not sure about how to turn off the swift optimizer for given pod. Can you please give me detailed step about how to do that for given pod. – Mehul Thakkar Sep 25 '19 at 05:15
Added an answer with a screen shot demonstrating it. – Paul Beusterien Sep 25 '19 at 17:03
Will surely apply this today once i get time. – Mehul Thakkar Sep 26 '19 at 05:38
