This is probably the worst persistentModelID not found message EVER!!!

is this going to part of iOS 18.2 release?

Thread 1: "-[NSURL longLongValue]: unrecognized selector sent to instance 0x303bd38e0" why would it try to cast it to longlongValue?!

When you combine this with the makeBackgroundContext below, does this solution merges the contexts correctly, for the background and main context?
