React Native / Expo iOS build compatibility issue with Particle RN SDK

[WonJo-Jung]

Hi Particle Network team,

We are evaluating Particle Network for a React Native mobile app built with Expo.

Our goal is to use Particle Auth / AA in a React Native iOS app, but we could not produce a successful EAS development build with the current RN SDK packages.

Environment tested:

• Expo SDK 54 / React Native 0.81
• Expo SDK 51 / React Native 0.74.5
• EAS iOS development build
• Xcode 16.x and Xcode 15.4 images
• New Architecture enabled and disabled
• CocoaPods with and without use_frameworks static linkage

Particle packages tested:

• @particle-network/rn-auth@1.4.19
• @particle-network/rn-aa@2.0.6
• @particle-network/rn-auth-core@2.0.6
• @particle-network/rn-base@2.0.6

Main issues observed:

1. With Expo SDK 54 / RN 0.81 / Xcode 16.x:

   • ParticleNetworkBase.framework appears to be built with Swift 5.10
   • Build fails due to Swift compiler / binary framework compatibility issues

2. With Expo SDK 51 / RN 0.74.5 / Xcode 15.4:

   • Without use_frameworks:
     • ParticleNetworkBase.swiftinterface fails to load Alamofire
     • ParticleAuthService.swiftinterface fails to load CryptoSwift

   Errors include:

   • cannot load underlying module for 'Alamofire'
   • cannot load underlying module for 'CryptoSwift'
   • failed to build module 'ParticleNetworkBase'

3. With use_frameworks: "static":

   • The Particle dependency module issue appears to move forward
   • But React Native Pods then fail during archive with:
     • 'react/debug/react_native_assert.h' file not found

We also tried:

• Downgrading Expo/RN versions
• Aligning React Navigation / Reanimated / Worklets versions
• Disabling New Architecture
• Setting iOS deployment target to 15.1
• Patching Particle podspec deployment targets
• EAS build with clear cache

Could you please provide an officially supported compatibility matrix for:

• Expo SDK version
• React Native version
• Xcode version
• iOS deployment target
• New Architecture support
• Required CocoaPods settings, especially use_frameworks / modular_headers

Also, do you plan to release updated React Native SDK binaries compatible with current Expo SDK / React Native / Xcode versions?

At the moment, we are blocked from using Particle RN SDK in an Expo iOS app because the native iOS build cannot complete.

Thank you.
