Hi @Shakhnoza
Signal 9 is a unix (i.e MacOS) error that means little more than “a process errored and was terminated by the operating system”, in this case MacOS. Unfortunately it tells you little more than that there is something amiss with your code - you’ll have to look elsewhere for clues as to where the issue lies. Hopefully you’ve solved it in the past few days since you posted. Have you managed to run the code successfully in the simulator, emulating the exact model and iOS version of your phone? It could be that your app uses a feature not supported on your particular phone/iOS combination. I think it’s highly unlikely that it’s something requiring an Apple Developer paid subscription, since things that require a paid subscription (e.g. persistence of data to iCloud) raise an error at design time pointing out that they need a subscription before they can be implemented within your project.
Fingers crossed you manage to debug the issue.
Cheers
