Can't get generated xcode project to compile

[WilliamIzzo83]

To test xchammer I tried the workflow on the Tailor sample code. I did the following:

cd sample/Tailor
xchammer generate XCHammer.yaml

And the output was the following

ERROR: /Users/William/Documents/work/clients/perceptolab/research/xchammer/sample/Tailor/BUILD:8:1: in ios_application rule //:ios-app:
Traceback (most recent call last):

		s.replace("'", "'\\''")
type 'NoneType' has no method replace()```

To mitigate this I changed the rules_apple.git repository tag to 0.19.0. At this point the project is generated but it won't compile. 
XCode output is the following:

:0: error: module map file 'tulsi-workspace/bazel-tulsi-includes/x/x/tailor.modulemaps/module.modulemap' not found
:0: error: module map file 'tulsi-workspace/bazel-tulsi-includes/x/x/tailor.modulemaps/module.modulemap' not found
:0: error: missing required module 'SwiftShims'

I'm using bazel 2.0.0

Thank you!

Doesn't work as well with the same error (master branch):

'NoneType' value has no field or method 'replace'

@WilliamIzzo83 did you fix it?

Hi @bigbangvn

unfortunately I was not able to make it work. From what I gather the problem show itself with newer bazel versions. For me this was kinda of a showstopper because I had hard contraints about it. I tried to update the rules involved, but in the end I had to give up.

In case this helps out anyone in the future, I ran into the same issue, for me, it was an issue with how xcode_project was being generated.

Specifically, i set:

        generate_xcode_schemes = False,

Doing this got things working for me.
