Question

我从Xcode得到以下错误。尝试了许多Internet上可用的解决方案，但没有用。

  ld: framework not found FirebaseInstanceID

我尝试过的解决方案：

尝试删除Podfile.lock和Podfile，然后通过以下方式再次启动：

pod init
pod install
pod update

我的Podfile如下：

# Uncomment this line to define a global platform for your project
platform :ios, '10.0'

# CocoaPods analytics sends network stats synchronously affecting flutter build latency.
ENV['COCOAPODS_DISABLE_STATS'] = 'true'    
project 'Runner', {
  'Debug' => :debug,
  'Profile' => :release,
  'Release' => :release,
}

def parse_KV_file(file, separator='=')
  file_abs_path = File.expand_path(file)
  if !File.exists? file_abs_path
    return [];
  end
  generated_key_values = {}
  skip_line_start_symbols = ["#", "/"]
  File.foreach(file_abs_path) do |line|
    next if skip_line_start_symbols.any? { |symbol| line =~ /^\s*#{symbol}/ }
    plugin = line.split(pattern=separator)
    if plugin.length == 2
      podname = plugin[0].strip()
      path = plugin[1].strip()
      podpath = File.expand_path("#{path}", file_abs_path)
      generated_key_values[podname] = podpath
    else
      puts "Invalid plugin specification: #{line}"
    end
  end
  generated_key_values
end

target 'Runner' do
  use_frameworks!
  use_modular_headers!
  # Flutter Pod
  copied_flutter_dir = File.join(__dir__, 'Flutter')
  copied_framework_path = File.join(copied_flutter_dir, 'Flutter.framework')
  copied_podspec_path = File.join(copied_flutter_dir, 'Flutter.podspec')
  unless File.exist?(copied_framework_path) && File.exist?(copied_podspec_path)
    # Copy Flutter.framework and Flutter.podspec to Flutter/ to have something to link against if the xcode backend script has not run yet.
    # That script will copy the correct debug/profile/release version of the framework based on the currently selected Xcode configuration.
    # CocoaPods will not embed the framework on pod install (before any build phases can generate) if the dylib does not exist.

    generated_xcode_build_settings_path = File.join(copied_flutter_dir, 'Generated.xcconfig')
    unless File.exist?(generated_xcode_build_settings_path)
      raise "Generated.xcconfig must exist. If you're running pod install manually, make sure flutter pub get is executed first"
    end
    generated_xcode_build_settings = parse_KV_file(generated_xcode_build_settings_path)
    cached_framework_dir = generated_xcode_build_settings['FLUTTER_FRAMEWORK_DIR'];

    unless File.exist?(copied_framework_path)
      FileUtils.cp_r(File.join(cached_framework_dir, 'Flutter.framework'), copied_flutter_dir)
    end
    unless File.exist?(copied_podspec_path)
      FileUtils.cp(File.join(cached_framework_dir, 'Flutter.podspec'), copied_flutter_dir)
    end
  end

  # Keep pod path relative so it can be checked into Podfile.lock.
  pod 'Flutter', :path => 'Flutter'

  # Plugin Pods

  # Prepare symlinks folder. We use symlinks to avoid having Podfile.lock
  # referring to absolute paths on developers' machines.
  system('rm -rf .symlinks')
  system('mkdir -p .symlinks/plugins')
  plugin_pods = parse_KV_file('../.flutter-plugins')
  plugin_pods.each do |name, path|
    symlink = File.join('.symlinks', 'plugins', name)
    File.symlink(path, symlink)
    pod name, :path => File.join(symlink, 'ios')
  end
end

# Prevent Cocoapods from embedding a second Flutter framework and causing an error with the new Xcode build system.
install! 'cocoapods', :disable_input_output_paths => true

post_install do |installer|
  installer.pods_project.targets.each do |target|
    target.build_configurations.each do |config|
      config.build_settings['ENABLE_BITCODE'] = 'NO'
    end
  end
end

pod 'FirebaseCore'
pod 'Firebase/Analytics'
pod 'Firebase/Performance'
pod 'Crashlytics', '~> 3.12.0'
pod 'GoogleSignIn', '~> 4.4.0'

我还确保我已经打开xcodeworkspace而不是xcodeproject。

为进一步说明，我也从Frameworks标签搜索路径中删除了此框架。

Answer 1

@Paul，您的回答一尘不染。根据您的建议，我设法消除了这个烦人的问题：

打开MyRockingApp.xcodeproj
链接->其他链接器标志->调试/发布
删除-framework“ FirebaseInstanceID”

非常感谢您！

Answer 2

经过12个小时的不间断浏览Firebase的DOC，并在Stack Overflow上实现了所有答案之后，我设法消除了这个错误。以下步骤是我为此所做的：

我安装的POD中不包含上述框架。因此，您需要从https://firebase.google.com/download/ios
下载SDK后，首先通过转到Xcode->首选项->位置->派生数据清除DerivedData。移至该目录并删除DerivedData文件夹。
删除Podfile.lock和Pods文件夹并执行pod init和pod install。
打开XCode并复制您下载的框架SDK的路径。对我来说是/user/Downloads/Firebase/FirebaseMessaging/FirebaseInstanceID.xcframework/ios-i386_x86_64-simulator，并将其复制到Framework Search Paths下的Build Settings中。
将名为FirebaseInstanceID.framework的文件夹拖放到Frameworks列表中，如问题的第二张图片（左侧）所示。

Answer 3

我怀疑Xcode项目对FirebaseInstanceID的引用一直存在。列出的吊舱的最新版本不需要它。

从Xcode项目中删除对FirebaseInstanceID的引用应该起作用。

Answer 4

从链接器列表中删除 -l"FirebaseInstanceID"。 [目标/构建设置/链接/其他链接器标志]。 更新 pod 时，它删除了库，但没有从 target.linker.list 中删除密钥。手动删除 pod.update 后不返回。

在Xcode上找不到框架FirebaseInstanceID
