cocoapods can't find simulators, pod repo push fails

do below steps it solved my issue For XCode 10.X and 11.X

  1. sudo gem update cocoapods

If above will not work for your system, follow the below 3 steps, it will surely work

  1. sudo gem uninstall fourflusher
  2. sudo gem install fourflusher
  3. sudo gem update cocoapods

If you have Xcode 10.1 installed, _even if Xcode 10.0 is set as the default version of Xcode, the output from simctl has a different format, specifically for availability. The rest of the fields appear to be the same, just not this one. You can see this JSON calling xcrun simctl list -j. And Cocoapods do not update their wrapper to this format yet.

I prepared temporary step-to-spet Hotfix of this issue. It work`s for me.

In log find this line - ERROR | [iOS] unknown: Encountered an unknown error (Could not find a iossimulator (valid values: ). Ensure that Xcode -> Window -> Devices has at least oneios simulator listed or otherwise add one.

Under it you will see such line: /usr/local/lib/ruby/gems/2.5.0/gems/fourflusher-2.0.1/lib/fourflusher/find.rb.

  1. Copy name of this file and call: sudo vi /usr/local/lib/ruby/gems/2.5.0/gems/fourflusher-2.0.1/lib/fourflusher/find.rb
  2. Press I
  3. In end of file find line with starts with Simulator.new(device, os_name, os_version)....
  4. Replace this line with Simulator.new(device, os_name, os_version) if device['availability'] == '(available)' || device['isAvailable'] == 'YES'
  5. Press :wq
  6. pod trunk push YourLibrary.podspec should work.

If something does not work, please reply.

The above solutions will work on a specific Xcode version. To get the solution that works with any Xcode version use the following. Rather than editing the file, you can copy entire content from https://github.com/CocoaPods/fourflusher/blob/master/lib/fourflusher/find.rb and replace.


I got this error after running the Xcode 10.2 beta. Unfortunately the previous answers didn't make the error go away. I don't know exactly what changed but I found a workaround to get it working:

  1. Find the find.rb of fourflusher, you can tell by the location on the error after running the pod trunk push command. Something like: /usr/local/lib/ruby/gems/2.5.0/gems/fourflusher-2.0.1/lib/fourflusher/find.rb
  2. Go to the end of the file around if device['availability'] == '(available)'
  3. Right below that make sure os_name and os_version are set. If you look in the comment above it expects to split # Sample string: iOS 9.3 into iOS and 9.3. In my case they were empty or something else so I set them myself.
  4. Also check the availability against true: || device['isAvailable'] == true

In the end that part looks like this: 

if device['availability'] == '(available)' || device['isAvailable'] == true
  os_name = "iOS"
  os_version = "12.1"
  Simulator.new(device, os_name, os_version)
end

THIS IS NOT A PERMANENT SOLUTION!!! It's just how I got it to work for now until what changed in the Xcode 10.2 beta is officially supported by cocoapods.

I noticed then when you run xcrun simctl list -j on a mac that never installed the beta you have os names like com.apple.CoreSimulator.SimRuntime.iOS-12-1 and iOS 12.1.

After installing the Xcode 10.2 I still see the com.apple.CoreSimulator.SimRuntime.iOS-12-1 but the iOS 12.1 one is gone. I'm assuming find.rb used the the latter to find the os_name and os_version values. This is why I set them myself.

Hope this helps other people, good luck!
