How to update settings for a swift/xcode project?

Question

I am new to Xcode and Swift . There is an apparently known problem in Swift Compilations that I am attempting to address via a recommended fix that is stated here https://forums.swift.org/t/swift-compilation-reaching-arg-max-limit-causing-xcode-build-failure/6494/14

Xcode 11 beta 3 added a flag to use an unlimited number of Swift files. You have to add USE_SWIFT_RESPONSE_FILE to YES in Build Settings - User Defined section. But this only works if you use the New Build System. Tested on a dummy project with 2000 files inside an extra long path and it's working.

I am uncertain how/where to add this USE_SWIFT_RESPONSE_FILE = NO setting. Here is my .xcodeproject directory

Which file should be updated to include the new setting?

Update After applying the accepted answer from @JawadAli the Target|Build|User defined settings are here:

Answer 1

xcode11

-build setting

-user-defined

-add setting: USE_SWIFT_RESPONSE_FILE (by pressing + sign on top)

-setValue:NO
