How is ios-sim being installed? Is it provided by Bitrise?

[jfirebaugh]

@1ec5 I don't know. I haven't successfully got the build to that point yet. It seems to be hanging on the first xcodebuild command for some reason:

https://www.bitrise.io/build/2ec0b5f61e76c0ef

Any ideas?

[1ec5]

Try nixing the package.sh invocation for now. Maybe the normal SDK build is interfering somehow?

[jfirebaugh]

Nope. Still hangs.

I guess I need to figure out how to get gyp to generate a scheme that's marked as "shared" when running make Xcode/ios.

[1ec5]

Ah, in that case, check out platform/osx/scripts/test.sh (make xctest). I have quite the hack for you in there.

[jfirebaugh]

Heh, wow, quite the hack.

I was going to go with a slightly different approach, of checking in the .xcscheme file from my local checkout, and copying it into place in the build script. That would be a temporary hack until #3275. Any reason to prefer the open / sleep approach instead?

[1ec5]

If xcodebuild is able to use that scheme, then great! I’m all for finding alternatives to my hack.

[jfirebaugh]

Well, it's successfully running the tests on iOS CI, but we can't see the output. 😢

[1ec5]

The simulator does support output to a file descriptor, but I'm not sure if ios-sim supports it. If it doesn't, you could also log to a file and print that file in a subsequent step that runs unconditionally.

[jfirebaugh]

ios-sim is supposed to handle that automatically. I discovered that there's a bug in the 3.1.1 version of ios-sim in homebrew which was fixed in 3.2.0. I submitted a homebrew pull request to upgrade.
