Solution : Unable to apply changes on device .. Unable to get application path on device..

[NickIliev]

@saxdevweb commented on Sun Nov 04 2018

I have the same problem I solved it as I explain in the picture.

Describe the solution you'd like 4- Once you have crushed the state of emulation. 5- Exit and close the emulator. 6- Restart the command: $ tns run ios

Normally the phone will completely reset itself to reinstall the application.

Describe alternatives you've considered i' havent alternative

[jfturcot]

Have you figured what's the problem? It is now impossible for me to work on iOS as the simulator needs to be erased every time I make a change on my Mojave MacBook and every time I make major changes on my High Sierra iMac. Let me know if you need more information.

Thank you for working on this issue.

Hi @jfturcot,

We released [email protected] version with various fixes related to issues with iOS simulator. I suggest you to install it on your side and give it a try.

[jfturcot]

@Fatme Thank you for replying. I installed it today, worked for the first couple of builds, then it broke again and I got the same error as before. It works fine when I do not --bundle the app.

+1 for this issue, I'm running into the same (or a similar) bug. Webpack watches for changes, and often succeeds in reloading the app. However, after like 10 changes, the app won't reload, and I need to cancel the build process and restart it again. Every time I perform this manual action, I get the Unable to apply changes on device error. I then have to remove the app from the device, and sometimes even erase the content from the simulator, before the build process will work again.

This happens pretty often and thus is a major annoyance during development. Colleagues working on the same projects don't run into this. I have tried reinstalling the Nativescript CLI but this hasn't resolved the issue.

[JonLevy]

+1. Having the same problem with NativeScript version 5.2.0.

[lolgzs]

+1, have the same problem too. One workaround I found is to open XCode ( open platforms/ios/MyApp.xcworkspace/ ) and build/run with xcode. Then stop and tns works again.

[rosen-vladimirov]

Hey @lolgzs , The issue happens when for some reason the iOS Simulator gets blocked by the requests CLI sends to it. In the last several versions of NativeScript CLI we've tried to fix this behavior and we are unable to reproduce it on our side at the moment. Of course, this doesn't mean we've fixed all cases, but we'll need some more details about your environment and the way you reproduce the error. Can you please send us the following information:

1. CLI version (output of tns --version)
2. Xcode version (output of xcodebuild -version)
3. Steps to reproduce the issue - every action and command you execute on your side to reproduce it.
4. The project with which you reproduce the issue - as it might be related to the size of the application.
5. Does the issue reproduce with simple Hello World application?
6. Does the issue reproduce with all simulators you have or with a specific one? Does the issue occur after you Erase the content of the simulator?
7. What is the simulator with which you reproduce the error, i.e. its OS version and device type?

Hey, can you execute tns run ios --log trace --justlaunch >out.txt and send us the generated file

[rosen-vladimirov]

Also can you provide the information required in my previous comment: https://github.com/NativeScript/nativescript-cli/issues/4095#issuecomment-474289922

Somehow webpack wasn't working, don't know why, but I pull the old version from github and it's fine now. Thanks!

Please let me know if I can provide more info. I couldn't get much out of trace as well.

Update After machine restart it started working for me. It is weird and completely random.

@relez I am having a similar problem, and I think it began when I updated webpack a few days ago. You said you pulled the old version from github and that helped. Can you tell me what you did and what version you are using now?

[relez]

Hey @NL33, I fixed the issue copying the webpack config sample from node_modules/nativescript-dev-webpack/templates/webpack.angular.js to the app folder and renamed to webpack.config.js.

That solved the problem!

Thanks!

Same issue. NS5 5.3.1. Previously erasing hardware data worked for me. But, I had to update my provisioning profile. Since then, I get the "unable to apply changes on device...Error is: Unable to get application path on device..." error on the simulator. Erasing hardware, restarting, etc. does not work any more.

Everything works fine running the simulator directly from xcode or running it on an actual device. But $ tns run ios leads to this error on the simulator.

[NL33]

The following worked for me to get my app running on the iOS simulator (at least today): specifying the device.

So, instead of $ tns run ios , I ran $ tns run ios --device "iPhone SE" (specific device probably doesn't matter). This command led to successfully installing the app on the simulator.

Remove node_modules, hooks and platforms folder using this command rm -rf node_modules/ hooks/ platforms/ . Then yarn install/npm install and run the application. It will fix the issue.

Updating runtime package.json with configuration values...

I was getting the same error, and the solution was very simple, there was missing Application folder in the data folder. So just created an Applications folder in the data folder and then run tns run ios It worked 👍

@suraj-bharti Could you elaborate on that a bit more? Where exactly do I have to create the folder? Get error

This solution worked for me. I am using the same environment as you.

Basically @suraj-bharti is saying is when you get the error copy up to data dir and manually create the Applications folder e.g.

cd /Users/username/Library/Developer/CoreSimulator/Devices/XXXXXXXXXX/data; mkdir Applications;

and rerun. No idea if permissions for this are missing or what the deal is.

@chirprooms Thank you very much! It didn't occur to me that I should actually do something on my local filesystem - I thought I had to do something in the emulator. With that it works perfectly. Thanks a lot!

[suraj-bharti]

Users/username/Library/Developer/CoreSimulator/Devices/XXXXXXXXXX/data/Applications

Basically, I want to say, we are getting the error because there no Application folder at that location. So, just create that folder that's all. mkdir -p Users/username/Library/Developer/CoreSimulator/Devices/XXXXXXXXXX/data/Applications
