React-native-ble-plx: Configuring React-native with React-native-ble-plx

[ibrahimAyyoub]

So I was following this guide: "https://blog.expo.io/so-you-want-to-build-a-bluetooth-app-with-react-native-and-expo-6ea6a31a151d"

At "3--IOS Setup" in first step, "pod install" I get this error I've got no idea why, I followed the exact guide.

Ibrahims-MacBook-Pro:appTestibrahim$ cd ./ios
Ibrahims-MacBook-Pro:ios ibrahim$ pod install

this is the error that I get:

I have the same issue

Same issue here. I don't totally understand cocoapods, but the only place I see a reference to react-native-ble-plx-swift is in the native-ble-plx-swift.podspec.json file, which seems to be generated every time you run pod install? I tried just commenting out the dependency in that file and it gets uncommented on running that command. I don't get where it's seeing this dependency.

[bradyrichmond]

Found the solution! You just need to add this line to your ./ios/Podfile:

pod 'react-native-ble-plx-swift', :path => '../node_modules/react-native-ble-plx'.

Then run pod install again.

If you have this error message "react-native-ble-plx-swift does not specify a Swift version"

It works after adding
ENV['SWIFT_VERSION'] = '3'

Thanks, guys 👍

[isa3bel]

where do you add EnV[SWIFT-VERSIOn] = 3? @diegochavez

[leechenghsiu]

@isa3bel at the top of your Podfile

I am getting the following error when I run pod install

"react": "16.11.0",
"react-native": "0.62.2",
"react-native-ble-plx": "^2.0.0",

'[!] No podspec found for react-native-ble-plx-swift in ../node_modules/react-native-ble-plx'

I have added the following 2 lines to the podfile

'pod 'react-native-ble-plx', :path => '../node_modules/react-native-ble-plx'
pod 'react-native-ble-plx-swift', :path => '../node_modules/react-native-ble-plx''

"react-native": "0.62.2",
"react-native-ble-plx": "^2.0.0",

'[!] No podspec found for react-native-ble-plx-swift in ../node_modules/react-native-ble-plx'

pod 'react-native-ble-plx-swift', :path => '../node_modules/react-native-ble-plx''

Note: You no longer need the following line with "react-native-ble-plx": "^2.0.0",
pod 'react-native-ble-plx-swift', :path => '../node_modules/react-native-ble-plx''

Same here!!!
