Can't build to phone

[talyh]

Using XCode Version 10.2.1, branch master, Unity 2018.2.11f1.

RN 0.57 used in the demo has an issue with this version of XCode, as indicated here: facebook/react-native#21071.

Patched RCTLinking using https://www.npmjs.com/package/patch-package, but still can't build to phone.

Order of operations:
a. npm install
b. installed patch-package
c. updated RCTLinking
d. ran patch-package
e. built from Unity ("Build => ExportiOS")
f. attempted build to iPhone XR

XCode throws error:

Any suggested workarounds?

@talyh Have you run demo successfully in iOS simulator?

@ham118 - I haven't, no. The company I work for decided not to invest more time in trying to get this to work, so I haven't looked at it in a while now.
