Following the recommendations of this video mobile apps going live I was able to test a mobile app I'm working on in Firebase Test Lab. The test was on virtual and physical android devices. When I tried to test the app in IOS a XCTests file was required. I tried to create it but all the tutorials I found online asumed that I have the XCode project instead of a builded file. 

Can someone show me how to create a XCTests file with the .ipa file provided by OutSystems.
