[REQUIRED] Step 1: Describe your environment

  • Xcode version: 12.0 beta 6
  • macOS Catalina 10.15.6
  • Firebase SDK version: branch 6.32-spm-beta
  • Firebase Component: Crashlytics
  • Component version: 6.32-spm-beta
  • Installation method: Swift Package Manager

[REQUIRED] Step 2: Describe the problem

When trying to use FirebaseCrashlytics in macCatalyst app, following compilation errors happen:

ld: symbol(s) not found for architecture x86_64
Undefined symbol: _CTRadioAccessTechnologyCDMA1x
Undefined symbol: _CTRadioAccessTechnologyCDMAEVDORev0
Undefined symbol: _CTRadioAccessTechnologyCDMAEVDORevA
Undefined symbol: _CTRadioAccessTechnologyCDMAEVDORevB
Undefined symbol: _CTRadioAccessTechnologyEdge
Undefined symbol: _CTRadioAccessTechnologyGPRS
Undefined symbol: _CTRadioAccessTechnologyHSDPA
Undefined symbol: _CTRadioAccessTechnologyHSUPA
Undefined symbol: _CTRadioAccessTechnologyLTE
Undefined symbol: _CTRadioAccessTechnologyWCDMA
Undefined symbol: _CTRadioAccessTechnologyeHRPD
Undefined symbol: _OBJC_CLASS_$_CTTelephonyNetworkInfo

Steps to reproduce:

  1. Install Firebase Crashlytics via SPM
  2. import Firebase
  3. Try to compile for macCatalyst

Opinion

I think this is happening because most of those constants are marked as API_UNAVAILABLE(macos).

Probably errors originate from here.

Possible solution - exclude calls to those constants using #if TARGET_OS_MACCATALYST, although i'm not 100% sure it's a complete solution for macCatalyst.

@DenTelezhkin Thanks for the report. Your suggestions sounds reasonable. We'll investigate more deeply this week.

Actually, it looks like those symbols should be available for Catalyst.

I'm able to work around by explicitly linking CoreTelephony:

I'll continue to investigate if there's a way to make this automatic.

@paulb777 Linking CoreTelephony explicitly works on my side too, thanks!

FYI, I also tried PR you opened to fix this(#6419), but it did not work on my side, producing the following:

Unknown type name 'CTTelephonyNetworkInfo'
Use of undeclared identifier 'CTRadioAccessTechnologyGPRS'
