Xcode IOS crashes when requesting IAP info

[Fernando]

ok, new beta should address this.

[Dobermann]

My app still crashes sometimes when doing the "request information for an item". It doesn't happen everytime, isn't possible to make a sort of security to only kill the IAP process and not crashes the whole app?

[Fernando]

check apple store report and see if you can get the whole crash

[Dobermann]

I have this log file on my phone, does it helps?

Could it comes from my events?

Actually i do that:

+ Run this event once
	 iOS Store : Request information for "sf.starterpack"

Shouldn't i do something like this instead:

* iOS Store Can payments be made?
+ Run this event once
	 iOS Store : Request information for "sf.starterpack"

[Fernando]

Short answer is YES.

inapp needs that.

[Dobermann]

Even with that modification i still get the same crash. It doesn't happen everytime, so i'm a bit confused and don't know where to look at...

I have the exact same problem and it doesn't happen all the time which makes it even harder to debug but the effect is 100% clear This is the iOS report after the update of our game

200% increase in crashes

[Dobermann]

That's a BIG problem, people who want to buy an in-app product get their app that crash, and we're losing revenues...

[Fernando]

We found in some apps CT developments that the error comes from SKRequest, but teh crash is internally in the framework (something form apple) what was done is to add some protection and therefore we made a new runtime let me know if you want to test, my test here seems Ok but want others to test before post.
