Cannot read property 'Symbol(Symbol.iterator)' of undefined during react-native-schemes-manager all

[richardgillzdev]

I've been trying to use the react-native-schemes-manager all with my xcodeSchemes set to

"xcodeSchemes": {
    "Debug": [
      "DebugStaging"
    ]
  }

I'm running node 7.10.0 and using "react-native-schemes-manager": "^1.0.0-beta.8", but keep getting the error

> react-native-schemes-manager all && (cd ios && pod install) && npm run check:node

Any thoughts you have would be appreciated

Encountering this issue this morning as well, seemingly out of nowhere

[kylealwyn]

Found my issue. I recently removed Debug field in xcodeSchemes config as it was causing some build issues but it seems to be required. You may want to try adding a Release key with an empty array as the value.

[thekevinbrown]

Yeah, the Debug scheme is definitely required as we copy its configuration all over the place. We should probably have a better error message for this though.

[thekevinbrown]

I tried in quite a few ways to get this to happen on a starter project today and couldn't replicate. @kylealwyn or @richardgillzdev, could either of you do up a repro case so I can fix this properly?

[adamtysonsmith]

I had this error and assumed it was trying to iterate through the Release array that I removed. I added it back in and everything ran fine:

"xcodeSchemes": {
    "Debug": [
      "DebugStaging"
    ],
    "Release": []
  }

You would then have 3 schemes:

Debug
Release
DebugStaging

[thekevinbrown]

Does anyone know if this is still happening in v1.0.3?

[orelmax]

@blargity just happened to me with v1.0.4. Although in my case i have an empty "debug" array.

[thekevinbrown]

Thanks @orelmax, next time I'm doing React Native stuff I'll have a look, or if someone wants to make a PR in the meantime that'd be very much appreciated!

Looks like it's still occurring on the latest version (2.0.0). I can take a closer look and hopefully make a PR to fix it
