Can you try following code DispatchQueue.main.async { let serverLangValue = ""// Server return value let switchEnum = "translate \(serverLangValue)" let text = "en" //(or any other language code) switch switchEnum { case "ABC": break case "QPR": break case "translate \(text)": break //From Xcode 16 and 15 swift compiler are file to process this case whereas older was working fine default: break } } } }

I can't share full code file or project, but here is case. I had setting file in that it calls API and in response callback I have DispatchQueue.main.async block to update UI. In response I am receving on "serverLangValue" . If you copy and check following code with any project, you will get Command SwiftCompile failed with exit code (since this small pics of code it show file name but in atual profject it's not pointing file) . After commenting "case "translate (text)": " It will work fine let serverLangValue = ""// Server return value let switchEnum = "translate \(serverLangValue)" let text = "en" //(or any other language code) switch switchEnum { case "ABC": break case "QPR": break case "translate \(text)": break //From Xcode 16 and 15 swift compiler are file to process this case whereas older was working fine default: break } }

Just for an update, After so many builds failed I finally got success. How do I resolve it? I removed all Swift file (storyboard and xib are fine) Build fine means a problem in Swift file Added one by one swift till error is not come, (started from utilities, model, singleton, database, ViewModel, Custom View, View) In one of file in my switch case var text = "en" (or any other language code) switch stringObject { case "ABC": break case "QPR": break case "translate \(text)": //From Xcode 16 and 15 swift compiler are file to process this case whereas older was working fine default: break }

Okay Thanks for your help really appreciated

I found the issue on code because of that those two services are running and taking memory here is the code let intArrayOfIds = self.respsonseDict.map{ Int($01234567890) ?? 0}

Anyone got any solution for this problem, I am not able to see download dSYM option in TestFlight, also I tried from organiser -> selected build -> Download dSYM but I am getting message "Their is not dSYM found." Can anyone help me on this. @Apple support please provide any solution on this problem
