How to stop MacOS Document-based App from automatically loading cached file

Question

On launching my app from Xcode, my document-based app automatically apparently tries to load a cached document from a previous launch. That document appears to be corrupted as the app crashes in initWithCoder [which was called from readFromData:].

The solution appears to be to delete the cached documents. Where are they located and is there anything special about deleting them?

Answer 1

I disabled the initWithCoder call which allowed me to launch the app. Then I opened a file known to be good and quit. Then I enabled the initWithCoder and launched again. No problems
