React-native-ble-plx: Tutorial failing to build with 'modulemap'

[yslee9311]

Expected

Xcode should build the project clearly.

Current

Get Error :

<unknown>:0: error: module map file '/Users/me/Library/Developer/Xcode/DerivedData/bleplx-gevvblkqzrxbjediwbytdxcmpufo/Build/Products/Debug-iphonesimulator/react-native-ble-plx-swift/react_native_ble_plx_swift.modulemap' not found

I installed it according to the manual and a problem occurred.
I don't know how to fix it.
How can i solve this problem?

i just spent a couple nights on trying to figure this out. after you follow the instructions open project.xcworkspace and build from that not the xcodeproj. worked for me after that

@chazguerrero Did you see any changes in your project's files after doing your last step? I would like to know if something changed.

[chazguerrero]

@Cierpliwy I didn’t, tonight I can try a new project with the same steps and let you know.

Getting the same problem with these dependencies:

{
    "react": "16.8.6",
    "react-native": "0.60.4",
    "react-native-ble-plx": "^1.0.3",
    "react-native-gesture-handler": "^1.4.1",
    "react-native-json-tree": "^1.2.0",
    "react-navigation": "^3.12.1"
}

Make sure to go to the ios folder and run pod update inside it. Remember to open the workspace file in the XCode (not a project). Do full clean/build cycle.

I'm just going to add on to this point here that if you are running using xcodebuild, you also need to target the workspace -workspace instead of -project.

For me also it worked by pointing out workspace instead of project.
