Xcode 10.1中的iOS cocoapods自动化测试

Question

我已经在Google上尝试了所有方法，但无法解决此错误。常规的构建工作正常，但UI测试始终会因该错误而失败。 https://github.com/CocoaPods/CocoaPods/issues/5250 https://github.com/CocoaPods/CocoaPods/issues/4752 我已经尝试了此链接上的所有内容。

import XCTest

class appUITests: XCTestCase {

    override func setUp() {
        super.setUp()
        continueAfterFailure = false 
        XCUIApplication().launch()
    }

    override func tearDown() {

        super.tearDown()
    }

    func testExample() {
    }
}

Podfile

project 'app.xcodeproj'

# Uncomment the next line to define a global platform for your project
platform :ios, '12.0.1'

target 'app' do
  # Comment the next line if you're not using Swift and don't want to 
use dynamic frameworks
  use_frameworks!

  # Pods for app
  pod 'Firebase/Core'
  pod 'Firebase/Database'
  pod 'Firebase/Storage'
  pod 'ProjectOxfordFace'

  target 'appTests' do
      inherit! :search_paths
    # Pods for testing
    pod 'Firebase'
  end

  target 'appUITests' do
      inherit! :search_paths
    # Pods for testing
    pod 'Firebase'
  end
end
