我的应用程序仅在我第一次登录时崩溃。它使用了 GoogleMaps (3.7.0) pod，我怀疑错误来自那个库:

这是 XCode 显示的跟踪日志。
编辑截图:
这就是我从 ViewModel 接收回调的方式。我在所有输出中添加了 DispatchQueue.main 以尝试避免此异常，但仍然弹出....
disposeBag.insert(
viewModel.outputs.onShowLoading
.bind { show in
DispatchQueue.main.async {
self.showLoading(show: show)
}
},
viewModel.outputs.onLoadDone
.bind { mapInfo in
DispatchQueue.main.async {
self.loadMap(mapInfo: mapInfo)
}
},
viewModel.outputs.onLoadError
.bind { error in
DispatchQueue.main.async {
print("ON LOAD ASSETS ERROR: \(error.localizedDescription)")
}
},
viewModel.outputs.onMultiClusterTap
.bind { paths in
DispatchQueue.main.async {
self.centerMap(paths: paths)
}
},
viewModel.outputs.onLoadAssetsInfoDone
.bind { assets in
DispatchQueue.main.async {
self.showBottomSheet(assets: assets)
}
},
viewModel.outputs.onDeviceChanged
.bind {
DispatchQueue.main.async {
self!.showDeviceChangedError()
}
}
)
编辑(2020 年 2 月 5 日): 我尝试使用 NBUIKitMainThreadGuard 查找错误
但我仍然找不到这些错误的来源。 此外，我发现在注销-登录后也会出现该错误。这不仅仅是我第一次安装该应用程序。
编辑(2020 年 7 月 5 日): 也许正如 Werner Altewischer 指出的那样，有一个图形库正在解决这个问题。这是我的 podfile，也许有助于解决这个问题:
source 'https://github.com/CocoaPods/Specs.git'
platform :ios, '11.0'
use_frameworks!
target 'WatchmanDoor' do
pod 'DropDown', '2.3.13'
pod 'GoogleMaps', '3.7.0'
pod 'GooglePlaces'
pod 'DKImagePickerController', '4.2.1'
pod 'Alamofire', '4.9.1'
pod 'iOSDFULibrary', '4.6.1'
pod 'RxSwift', '~> 5.0.1'
pod 'RxCocoa', '~> 5.0.1'
pod 'Swinject', '~> 2.7.1'
pod 'SwinjectAutoregistration', '~> 2.7.0'
pod 'SwinjectStoryboard', '~> 2.2.0'
pod 'FittedSheets', :git => 'https://github.com/WatchmanDoor/FittedSheets.git', :commit => '9824dd171499967226a4dd160aedc7d4d9db3a11'
pod 'SDWebImage', '~> 5.5.0'
pod 'NavigationDrawer', '1.0.2'
end
会不会是 FittedSheets pod 引发了错误？我 fork 存储库以更新它以支持 Swift 5，但可能是导致异常的原因。
更新: 仍然面临同样的错误......找不到别的 -_- 知道从哪里开始吗？

重要更新: 我发现，当应用程序崩溃时，我的堆栈 View 充满了 UITRANSITIONVIEW。不知道这个有没有关系...
解决方案 [13/05/2020] 所以我想我找到了错误的来源。请参阅下面的答案。
最佳答案
显然，有问题的后台线程(线程 17)正在直接访问一些 UIKit 方法，这通常是不允许的(只能从主线程完成)。
您是否使用 GCD 的分派(dispatch)异步在后台线程上分派(dispatch)了一些方法？
