SecKey API returned: -25304 libswiftAVFoundation.dylib: unknown error -1 = ffffffffffffffff error: task failed with exit 1 0

Question

Since update 10.12 of Sierra, I can’t compile one of my iOS projects on a device only . But very strange, it works on a simulator. I tried to delete and restore my dev account in Xcode, perform a hard reboot, delete and restore all certificates in the keychain, etc. Xcode 8.0. I also tried also on beta 8.1.

Error:

I had the same problem

Unlock the keychain by adding this line to the project configuration (Build> Execute shell)

# close the keychain
security key keychain -p "myPrettyPassword" $ HOME / Library / Keychains / MyPrettyKeychain.keychain
