The iOS app is working fine when we download and install from testflight if I generate that app from Xcode 9.1 and MacOS 10.13.6(High Sierra)and uploaded to testflight.I have opened the same code from Xcode 11.3 on latest MacOS Catalina and generated iPA and uploaded to the testflight using proper distribution certificate. I was able to download and install app but app is crashing during app launch.
Please suggest me what could be the reason for this issue. I am adding some app crash logs from my iPhone.

I have fixed this crash by renaming RKResponse class name of Restkit framework by adding some prefix to it. So that it will not conflict with RKResponseKit framework class RKResponse
