Always have to run plugin tests twice on iOS - Failed to load Info.plist from bundle at path

[NickIliev]

Tell us about the problem

I have a fairly basic plugin that was generated using the seed template. I have written some tests and can run them successfully on iOS and Android through the included demo app.

However, on iOS I always have to run the test twice for it to work. The first time it always errors with:

npm run ios:test

...

I can simply run the same test script again (npm run ios:test), it it works. This happens every single time no matter what I have tried.

Basically, the iOS test command only works every other time it is ran.

This is through the simulator. I have also tried clearing the ./demo/platforms directory, but that didn't seem to change anything.

Which platform(s) does your issue occur on?

iOS

Please provide the following version numbers that your issue occurs with:

• CLI: 4.2.2
• Cross-platform modules: 4
• Runtime(s): 4.2

Please tell us how to recreate the issue in as much detail as possible.

You can download my plugin code here:
https://github.com/bitwarden/mobile/tree/ns2/plugins/bw-crypto

Then run

npm i
npm run ios:test

Observe failure. Then run

npm run ios:test

Observe success.

Is there code involved? If so, please share the minimal amount of code needed to recreate the problem.

Hi @kspearrin,

I've noticed similar behavior after upgrade to Xcode10. What is you Xcode version?

[NickIliev]

From @kspearrin on October 1, 2018 1:46

@dtopuzov Yes, I am using xcode 10.0

[ricmello]

This happened with me after upgrade to xcode 10.0, but I solved it by erasing all content and settings of simulator.

[kspearrin]

@Ricardo-Mello I tried "Erase all content and settings" on this simulator (iPhone 6), yet the same problem still seems to be occurring.

[rosen-vladimirov]

Hey @kspearrin ,
Thanks for reporting this issue. We have reproduced it on our side, but unfortunately it looks like this is a problem in the xcrun install command. We have managed to reproduce the issue (sporadically) without using NativeScript CLI, just running:

xcrun simctl install <simulator identifier> <path to .app> 

The only workaround that we can implement in the moment is to retry the operation in case it fails. It is not a great solution, but it will fix the current issue. We'll try this approach and write back here once we have at least this fix applied.
