Packaging error when switching to arm64 (arm5 was OK)

Question

I just plugged in a new iPhone 6, created a provisioning profile and then I launched the app I'm developing on the device. It compiled fine, but at linking stage it errored out with:

ProcessProductPackaging

...

error: class '(null)' of input object does not respond to either selector writeToFile:options:error: or writeToFile:atomically

I cannot find any information of what that is. I do not get any specific code reference to relate it to. Did anyone experience this?

Answer 1

I just restarted Xcode then the error was disappeared

Answer 2

Personally I was able to solve this issue by rebuilding the project a second time. I think I was only experiencing it after revoking and requesting a certificate.

Odd for it to jump at me and disappear though.

Answer 3

I've tried turning the "Automatically managed signing" off and on again, then the issue disappeared. Note: rebuilding didn't help for me, cleaning either.

Answer 4

I removed an external library and related code I had and it's now working.

Answer 5

I just changed some provisioning setting and then restarted the xcode afterwards the error was disappeared and archived and then uploaded successfully
