After multiple trials and errors, here are the steps that I finally got it through in case anyone encounter the similar issue : OpenKeychain Access, in the search bar, type ‘apple’, I notice somehow I have 2 Apple Development: xxxxx private key [ xxxx => your name ]. So, I delete both since I don’t know which to retain, their content both look identical after inspect. Back to Xcode -> Preferences -> Accounts -> Add back my AppleID Run the app, on the code sign prompt, enter the computer password, then click Always Allow directly

Hi @lars.lindback, I'm facing the same issue with the Codesign fail scenario as @margotedxsi mentioned, there's no OK button and can't leave it blank either... Anyone else has encountered this issue? I can't proceed to run the app and test codes further at this stage to verify the developed features.. Kindly advise what could have gone wrong. Thanks.
