Error when build project in new Xcode 8.0 beta
I combatted this last night. I assume you are using Pods: For each Pod, change the Team under Signing (as shown here)
edit: Screenshots are in Xcode 8 (now)
I stole this from Anish:
Project tab -> list of Targets -> General tab for the target xcode complains about (in my case that's my framework used by my applications) -> choose your team
My project does not use pods. Sheesh.
UPD: now my project has picked up developers from the brave new world and it does use pods now (sudo hardlyagem install cocoapods), but that's hardly relevant since the solution I stole from Anish predates the import of boatload of 3rd party problems, all alike
