Question

iOS simulator crash in iOS 8.2 and Xcode 6.2 with an error below

"Failed to lookup the process ID of xxx.xxx.xxx after successful launch. Perhaps it crashed after launch. No such process".

And I cannot try to simulate my app.

I uploaded the image of error.

It works normally when i use iOS 8.1 as a simulator. Regardless of the types of devices and types of projects, it will crash in iOS 8.2 simulator.

The iOS simulator itself stands but has nothing on the screen.

A thing I care is that I changed my old macbook to new one and copy project files of Xcode from old to new.

Do you have any idea of this?..

Answer 1

I had the same problem after I did a Mac update on xcode. I had the IOS simulator open during the install/update process. When I closed it, re-ran my compile, it re-opened the simulator and ran fine.

Answer 2

Even i had the same issue when i upgraded Xcode to 6.3.2. I just did re launch of Xcode and iPhone Simulator and worked for me.

Answer 3

I had the same problem and solved it by force quitting and restarting Xcode and iOS Simulator.

Answer 4

Simulator -> Reset Content and Settings did it for me.

Answer 5

I had the same problem, in my case the issue was :-

Have set "Build active architectures : NO". Just changed it to YES and it worked.

Answer 6

In my case, all I needed to do was: Hardware -> Reboot on simulator.
