i know that this question has been posted a lot of times but the suggested solutions doesn't fit my case, when i try to build and run my app on the simulator, i got this error and it crashes:
Couldn't register test.My-App-Name with the bootstrap server. Error: unknown error code.
This generally means that another instance of this process was already running or is hung in the debugger.
I tried to create a new app with Xcode with the same name but i got the same issue. However, when i try to make a different app(different name) in Xcode, it run pretty good.
Does any one know how to solve that problem.
