react-native run-ios only works the first time after pods are installed

Question

I have to follow this guide every time I wish to start my app on iphone simulator: https://stackoverflow.com/a/55776414/4662347

I used to not have any problems, but since I started using pods this problem appeared.

First time when I run react-native run-ios it works. But then second time when I try running it fails like this:

error Failed to build iOS project. We ran "xcodebuild" command but it exited with error code 65. To debug build logs further, consider building your app with Xcode.app, by opening KoirapuistoApp.xcworkspace

If I run it from xcode it fails like this:

ld: library not found for -lDoubleConversion...

But in xcode if I open my app as myApp.xcworkspace, then build will succeed. Problem is I can't develop through xcode, I need the react-native run-ios command to work.

My Pods file looks like this:

project 'MyApp.xcodeproj'

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

# Allowed sources
source 'https://github.com/CocoaPods/Specs.git'

target 'myapp' do
  # Comment the next line if you don't want to use dynamic frameworks
  use_frameworks!

  # Pods for myapp

  # Point to the installed version
  pod 'RNDateTimePicker', :path => '../node_modules/@react-native-community/datetimepicker/RNDateTimePicker.podspec'

  # React/React-Native specific pods
  pod 'React', :path => '../node_modules/react-native', :subspecs => [
    'Core',
    'CxxBridge',      # Include this for RN >= 0.47
    'DevSupport',     # Include this to enable In-App Devmenu if RN >= 0.43
    'RCTText',
    'RCTNetwork',
    'RCTWebSocket',   # Needed for debugging
  ]

  # Explicitly include Yoga if you are using RN >= 0.42.0
  pod 'yoga', :path => '../node_modules/react-native/ReactCommon/yoga'

  # Third party deps podspec link
  pod 'DoubleConversion', :podspec => '../node_modules/react-native/third-party-podspecs/DoubleConversion.podspec'
  pod 'glog', :podspec => '../node_modules/react-native/third-party-podspecs/glog.podspec'
  pod 'Folly', :podspec => '../node_modules/react-native/third-party-podspecs/Folly.podspec'

  target 'myapp-tvOSTests' do
    inherit! :search_paths
    # Pods for testing
  end

  target 'myappTests' do
    inherit! :search_paths
    # Pods for testing
  end

end

Question is, how do I get the app working every time when I issue the basic dev command?:

react-native run-ios

My react-native version: 0.59.10

Was able to hack fix this by setting the build mode in xcode to legacy mode:

File -> Workspace settings -> Build system -> Legacy build system.

After this I no longer need to delete the build folder after each run of: react-native run-ios

But since apple will remove the legacy build system soon, I don't think this is a good long term solution. If anyone figures out a proper solution I might accept it instead.

react-native run-ios only works the first time after pods are installed
