Use of undeclared identifier 'Roam'

[ThushalIntervest]

Currently, we are using,
React Native : 0.68.2,
we are using AppDelegate.mm files containing Objective-C++

[nikhil290]

Hi can you initialise Roam inside

#if RCT_NEW_ARCH_ENABLED

[ThushalIntervest]

@nikhil290 thank you, This solution work. After that when I going to create a test user, I got this error.

Hi can you check if you making any mistake in passing publishable_key or bundle_id ?

publishable_key is empty : Data not found
**Incorrect bundleId & publishable_key ** : Either publishable_key or bundle_id is wrong

[ThushalIntervest]

@nikhil290 Here are our configurations for the iOS app. but when creating users above error is occurring. We have 3 schemes dev, prod and uat for each environment.
In android we used the publishable key with com.wappapp.android.dev and it worked as expected.
For the iOS, we use publishable_key key with bundle_id(com.wappapp.ios.dev) but it didn't work. publishable_key same for android and iOS.
if you can assist as soon as possible that will be really helpful.

[nikhil290]

Hi @ThushalIntervest

Can you downgrade react native to 0.64.3. and check again ?
Mean time Our developer looking into the above error

[ThushalIntervest]

Thank you for the suggestion @nikhil290 🙏 . We can test with React Native 0.64.3 but we want to continue with React Native 0.68.2 Because it will impact our other Libraries. For that can you please give an update on when you found the solution for this error 🙏.

[hamidhadi]

We have the same issue. Any updates on this?

[nikhil290]

Hi @hamidhadi @ThushalIntervest yes we are working on it and will share an update asap .

[nikhil290]

Hi @hamidhadi @ThushalIntervest
https://reactnative.dev/docs/0.68/new-architecture-app-intro#ios-use-objective-c-mm-extension
You can follow below steps to fix the issue

1. Rename AppDelegate.mm to AppDelegate.m directly in xcode.
2. Call Roam initialize before #if RCT_NEW_ARCH_ENABLED if they are not setting USE_FABRIC=1 RCT_NEW_ARCH_ENABLED=1 while installing pods.

[hamidhadi]

Hi, @nikhil290
Thanks for your reply. I'm not sure we want to change the file extension as it might affect other turbo modules.

[ThushalIntervest]

@hamidhadi true, I did the same thing previously. it didn't work and after kill sometimes the app crashed and the location tracking not worked.

[nikhil290]

Hi @hamidhadi it is working from our end , we are trying to replicate it the above mentioned crash and will update you soon

[hamidhadi]

@nikhil290 Even if that works now, we can't ensure that it won't affect the other libraries as your proposed solution is changing the RN signature.
Still, I tried to run the app after applying your solution, and I'm getting the following error:

Error: NativeModules.RNRoam is undefined, js engine: hermes

[ThushalIntervest]

@hamidhadi for that you need to,

• Open the iOS module files, located inside node_modules/roam-reactnative/ios/.
• Open the app workspace file (AppName.xcworkspace) in Xcode.
• Move the RNRoam.h and RNRoam.m files to your project. When shown a popup window, select Create groups.

[hamidhadi]

Thanks, @ThushalIntervest!
I believe the auto-linking issue was supposed to be fixed as part of this release
