Replace deprecated completion block
Browse files Browse the repository at this point in the history 
Summary:
`UIActivityViewConroller.completionHandler` has been [deprecated](https://developer.apple.com/reference/uikit/uiactivityviewcontroller/1622010-completionhandler) since iOS 8, when it was replaced by `completionWithItemsHandler`.

Tested the build using `UIExplorer` and XCode 8.2 but I've never seen and can't work out how to activate the `UIActivityViewController` this method relates to, so I haven't tested a real run.
Closes #11798

Differential Revision: D4396618

After this change was made, I always get an error running react-native run-ios, and always have to revert back this on my node_modules. Please fix.

Same story. Fails to compile because of this.

What version of Xcode are you using? Perhaps it is old?

Actually figured out you cannot run the latest stable react-native version if you are not running on OS Sierra, (for you to have the latest version of Xcode)

In general, React Native usually supports and sometimes requires the latest version of macOS and Xcode, so update frequently.

It's a breaking change for me too. I use Xode 7.3 and iOS 9.0:

Incompatible block pointer types assigning to 'UIActivityViewControllerCompletionWithItemsHandler _Nullable' (aka 'void (^)(NSString * _Nullable __strong, BOOL, NSArray * _Nullable __strong, NSError * _Nullable __strong)') from 'int ((^)(void))'

and

Expected ')'

It looks like this changed in RN 0.42 -- I added a mention of this breaking change to the release notes. I think the release maintainers didn't encounter this issue because they (and the test suites) are using the latest version of Xcode. https://github.com/facebook/react-native/releases/tag/v0.42.3

Generally speaking, the latest major version of Xcode (e.g. the 8.x releases) is the only supported version. Sometimes when a new version of Xcode has just come out, the older version is supported for awhile but you should upgrade in a timely manner.
