RCPurchases dealloc is not called about purchases-ios

[MichaelDanielTom]

Not sure if this is related, but we're getting a bunch of EXC_BAD_ACCESS crashes in production from [RCPurchases cachePurchaserInfo:]. It's hard to reproduce locally. I included a stack trace - hopefully this can be helpful!

@MichaelDanielTom how do you init Purchases and reference the object after? From my point init of the singleton is a bit weird and actually you still can have multiple objects that a listening to delegates. This might cause the issue.

Hey Michael,

That is an interesting crash. We haven't seen it reported before but it looks like maybe NSUserDefaults has a dealloced observer somewhere in your app?

I sent you an email about it.
