It seems I wrongly parsed argument types: ``` marketSellOrders((address,address,address,address,uint256,uint256,uint256,uint256,uint256,uint256,bytes,bytes)[],uint256,bytes[]) ```

@jpmgoncalves just checked, it helps. Please merge it and build a new release. 

I think this may happens because of iPhone locking. It always auto-locks because of touch-ID enabled. So some keychain items can be unavailable IMHO.

I've solved problem by caching keychain data in property. ``` @property (nonatomic, strong) NSData *privateKey; ... - (NSData *)privateKey { if (_privateKey == nil) _privateKey = [UICKeychainStore dataForKey:@"mykeytag"]; return _privateKey;...

Just cache this value in property.

Ok, I'll provide it in a few days. Can you comment what weakSender is doing in this code? Looks like weakness is really have no influence in that exact place.

Here is problem description with weak pointer creation in dealloc: http://stackoverflow.com/questions/19907616/how-can-i-reference-weak-self-in-dealloc-method

Creating `__weak` from `__strong` to create `__strong` again when passing argument to block is really useless, but cause a crash if occurs in `sender`'s dealloc.

Really I would like to setup update suggestion for my app without any own backend. Don't wanna care of this dependency never. Just wanna add binaries to GitHub Releases page.

@pornel do you mean include `appcast.xml` in git repository files? I think it can be done, by filling template and appending to xml file or add terminal tool to add...
