Xcode 12：在 FIRAnalyticsConnector 上构建错误

Question

After upgrading to Xcode 12, my project doesn't build for the simulator anymore.

The error I get is:

ld: in ... /Pods/FirebaseAnalytics/Frameworks/FIRAnalyticsConnector.framework/FIRAnalyticsConnector(
FIRAnalyticsConnector_e321ed8e3db06efc9803f6c008e67a34.o), 
building for iOS Simulator, but linking in object file built for iOS, file
'.../Pods/FirebaseAnalytics/Frameworks/FIRAnalyticsConnector.framework/FIRAnalyticsConnector'
for architecture arm64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

A workaround is adding arm64 to my project > Build Settings > Excluded Architectures, but then it won't build for my real device.

I already tried cleaning the build folder, updating pod file, restarting etc.

I'm using:

• Firebase/Analytics (6.33.0)
• Xcode 12.0.1 (12A7300)
• CocoaPods: 1.9.3

Any ideas?

Answer 1

Ok, I finally found a fix for the issue.

Change "Build Active Architecture Only" to "Yes" also for "Release".
The setting can be found selecting your project > "Build Settings" > "Targets" (your target) > "Architectures"

Please note that the problem is not related to Firebase. I'll still leave it since it might lead others to this issue and help them to resolve this.

Answer 2

I fixed the issue by running xcode12 under Rosetta (Apple M1).

Open Finder -> Application -> locate Xcode -> right click -> get info -> check open using rosetta.

then reopen xcode.

Answer 3

After adding arm64 to Excluded Architectures for the main project AND for the Pods project, I was able to resolve this issue I ran into on an Apple M1.

I also had to clear the DerivedData folder and restart Xcode.

Answer 4

My case was a little different. According to this Firebase engineer ,

FIRAnalyticsConnector is now part of the xcframework version of FirebaseAnalytics and isn't needed to link.

Going into the Targets Build Settings (not the Project), searching for Other Linker Flags , and then deleting FIRAnalyticsConnector from the list took care of the issue for me.

Interestingly, when I ran pod deintegrate and the pod install it did not fix this issue.

Answer 5

Had same problem in Xcode v12.4 after running pod install .

After some searching inside my project I finally found reference to it under target's Build Phases in Link Binary With Libraries section. Removing FIRAnalyticsConnector.framework from the list solved my problem.

Answer 6

从目标列表中删除 -fraemwork "FIRAnalyticsConnector" -> "build settings" -> OTHER_LDFLAGS

Answer 7

最后，按照此链接https://github.com/firebase/firebase-ios-sdk/blob/CocoaPods-7.2.0/AppleSilicon.md 中的说明，解决了它。

Answer 8

if you run on Apple Silicone with new Macbook Pro M1 processor. This is a known issue.

Firebase not compiling on Apple Silicone

Answer 9

that worked. I open Xcode using Rosetta.

Step 1 - Installation

Homebrew(recommended)

brew install 417-72KI/tap/xcode-arch

Usage

$ xcode-arch -p
arm64 # `Open using Rosetta` is off
$ xcode-arch -c
Set x86_64 for /Applications/Xcode.app
$ xcode-arch -p
x86_64 # `Open using Rosetta` is on
$ xcode-arch -u
Set arm64 for /Applications/Xcode.app
$ xcode-arch -p
arm64 # `Open using Rosetta` is off
