[iOS] Can't build without ARC errors

[jonestheguitar]

RNFetchBlobNetwork.m:32:13: ARC forbids synthesizing a property of an Objective-C object with unspecified ownership or storage attribute
RNFetchBlobNetwork.m:35:13: ARC forbids synthesizing a property of an Objective-C object with unspecified ownership or storage attribute
RNFetchBlobNetwork.m:36:13: ARC forbids synthesizing a property of an Objective-C object with unspecified ownership or storage attribute
RNFetchBlobFS.h:18:28: Existing instance variable 'callback' for property 'callback' with unsafe_unretained attribute must be __unsafe_unretained

I'm using 0.5.3.
Is it because I've added the project manually rather then with rnpm and have missed some build flags?

The properties it's complaining about are:

@Property (nullable, nonatomic) RCTResponseSenderBlock callback;
@Property (nullable, nonatomic) CompletionHander fileTaskCompletionHandler;
@Property (nullable, nonatomic) DataTaskCompletionHander dataTaskCompletionHandler;

Hi @jonesdar , I think this problem is similar to #30 , I'm still trying to reproduce this error, looks like these block properties can't be nullable, if you remove nullable from those properties, do you still get the error ?

Hello. No that doesn't help. Adding strong fixes things though - is that the right thing to do?
It's interesting that you don't see these errors - is it related to the version of Xcode perhaps? I'm using 7.2.

I think it might be Xcode version related. Our build machine has just built things successfully and it's using Xcode 7.3.

@jonesdar great thanks ! I'm using Xcode 7.3 and I can build it without error, I'll release a version after doing some test.

Thanks @wkh237. That fixes the 3 errors in RNFetchBlobNetwork.m. The one in RNFetchBlobFS.h is still there though. Adding strong to @property (nonatomic) RCTResponseSenderBlock callback; seems to fix it.
