Question

我遇到一个奇怪的问题，FirebaseApp.configure()调用导致我的应用程序立即崩溃我的单元测试目标。它对我的标准构建运行良好。

为什么会发生这种情况？

这是堆栈跟踪：

bc ++ abi.dylib：以NSException类型的未捕获异常终止

在崩溃之前，我还看到了大量的日志条目，如：

objc[14289]: Class RCNKeyValue is implemented in both /Users/sammcneilly/Library/Developer/CoreSimulator/Devices/E62EC87E-0B07-4A83-A165-819E693AEB87/data/Containers/Bundle/Application/6C3F993F-4CEB-462F-9257-0F3C8E088BC0/Avalanche.app/Avalanche (0x10f7bdd50) and /Users/sammcneilly/Library/Developer/Xcode/DerivedData/Avalanche-ewiqmxxekhpknrhhfuyljlekgzat/Build/Products/Development-iphonesimulator/Avalanche.app/PlugIns/Avalanche Tests.xctest/Avalanche Tests (0x129e075d8). One of the two will be used. Which one is undefined.

我已经通过CocoaPods安装了Firebase和Firebase / Crashlytics。我不确定这是否与Xcode 9.3有关 - 这是在两个独立的项目中发生的，我相当确定它以前没有发生在旧项目中。

我打印出了包内容，GoogleService-Info.plist文件似乎就在那里。

非常感谢任何帮助！

Answer 1

好的，原来这是由错误配置的Pod文件引起的。我的主要目标和单元测试目标配置为使用以下pod：

pod 'Crashlytics', '~> 3.10.1'
pod 'Fabric', '~> 1.7.6'
pod 'Firebase/Core', '~> 4.8'
pod 'FirebaseRemoteConfig', '~> 2.1'

仅为测试目标移除其他Firebase容器（Firebase/Core除外）并再次运行pod install有帮助。

我并不完全确定为什么这是有效的，所以如果有人能向我解释这一点，我将非常感激。

我的主要目标上配置了"${PODS_ROOT}/Fabric/run"构建阶段脚本，详见Google的文档：https://firebase.google.com/docs/crashlytics/get-started，并将其添加到测试目标也没有帮助。 ..

感谢大家的输入，但手动将Fabric详细信息添加到Info.plist文件只会导致构建错误。我相信此步骤会自动为Firebase处理。

Answer 2

将此代码放入info.plist

<key>Fabric</key>
    <dict>
        <key>APIKey</key>
        <string>YOUR APIKEY</string>
        <key>Kits</key>
        <array>
            <dict>
                <key>KitInfo</key>
                <dict/>
                <key>KitName</key>
                <string>Crashlytics</string>
            </dict>
        </array>
    </dict>

希望它有所帮助。！

运行XCTest时，我们发生了相同的崩溃。我们使用以下方法来解决它。

        if NSClassFromString("XCTest") != nil {
            return true
        } else {
            FirebaseApp.configure()
        }

FirebaseApp.configure（）崩溃了单元测试目标
