iOS simulator can't find app because incorrect case of "Build" in path

[jeffswitzer]

Environment Provide version numbers for the following components (information can be retrieved by running tns info in your project folder or by inspecting the package.json of the project):

• CLI: 6.1.2

Describe the bug Trying to migrate a project from 5.4 to 6 and having trouble running on the iOS emulator due to case sensitivity of the build path. Seems like 5.4 used 'build' but 6 changed this to 'Build'.

Replicate tns platform remove ios tns platform add ios tns run ios --emulator

I get: Project successfully built. The build result is located at: /Users/npn/Development/ns6/test/platforms/ios/build/Debug-iphonesimulator/test.app Installing on device 84F073AE-D836-4C81-8803-FDA3ABC8C731... Unable to apply changes on device: 84F073AE-D836-4C81-8803-FDA3ABC8C731. Error is: Command xcrun with arguments simctl install 84F073AE-D836-4C81-8803-FDA3ABC8C731 /Users/npn/Development/ns6/test/platforms/ios/build/Debug-iphonesimulator/test.app failed with exit code 2. Error output: An error was encountered processing the command (domain=NSPOSIXErrorDomain, code=2): Failed to install the requested application An application bundle was not found at the provided path. Provide a valid path to the desired application bundle.

Expected The issue is in the case of the word build in the path. On my drive tns is creating /Users/npn/Development/ns6/test/platforms/ios/Build/Debug-iphonesimulator/test.app but it's giving args to simctl as /Users/npn/Development/ns6/test/platforms/ios/build/Debug-iphonesimulator/test.app

Other than manually adjusting the path on my file system how do I get the two to agree on the case?

Hey @jeffswitzer,

We'll need additional information in order to help you to resolve the problem. Can you please send us the followings:

• The version of CocoaPods - you can get it using pod --version
• The version of Xcode - xcodebuild -version
• The content of your package.json file.

Also, can you reproduce the issue using a newly created blank application?

[Fatme]

@jeffswitzer,

Meanwhile, we tried to reproduce the problem using case-sensitive file system, but without success. It seems on our side that the build folder is always created with lowercase b. Also, we've hardcoded the path to build folder and it is really strange how it is possible to be outputed in Build directory.

[jeffswitzer]

@Fatme,

Thanks for looking into this. Here is more info:

1. pod --version = 1.5.3
2. xcodebuild -version = Xcode 11.0 Build version 11A420a
3. The problem does occur with a newly created blank application.
4. Here is the package.json from the project created with tns create testing2 --ng

Hey @jeffswitzer,

Thank you for sending the information!

Can you try the following steps:

1. Remove the DerivedData of your application

The default location of the project's derivedData is /Users/<username>/Library/Developer/Xcode/DerivedData/<projectName>-<guid>. In case you cannot find it at that location, you can open the native project in Xcode, go to Xcode menu -> Preferences -> Locations -> Derived Data.

2. Remove the platforms folder of your application
3. Execute tns run ios --emulator

Let us know if that helps.

[jeffswitzer]

Didn't seem to help. I removed the derived data folder:

(base) [npn@on-campus DerivedData]$ pwd
/Users/npn/Library/Developer/Xcode/DerivedData
(base) [npn@on-campus DerivedData]$ rm -rf testing2-ealggwqrnpsclqdikswczlrtkofi/

Then I removed the platforms folder and when it got recreated it still added the directory as Build and gave the same error. Here is the contents of /Users/npn/Development/ns6/testing2/platforms/ios

Here is the error output:

@jeffswitzer,

I removed the derived data folder:

(base) [npn@on-campus DerivedData]$ pwd
/Users/npn/Library/Developer/Xcode/DerivedData
(base) [npn@on-campus DerivedData]$ rm -rf testing2-ealggwqrnpsclqdikswczlrtkofi/

Sometimes there are more than one folder in format <project-name>-<guid> inside /Users/npn/Library/Developer/Xcode/DerivedData. Can you ensure that all folders that started with testing2 are deleted?

If the above didn't help, rename /Users/npn/Library/Developer/Xcode/DerivedData to /Users/npn/Library/Developer/Xcode/DerivedData1, delete platforms folder of your project and try again.

[jeffswitzer]

@Fatme there was only one folder that started with testing2. I tried renaming the DerivedData folder:

(base) [npn@on-campus Xcode]$ mv /Users/npn/Library/Developer/Xcode/DerivedData/ /Users/npn/Library/Developer/Xcode/DerivedData1
(base) [npn@on-campus Xcode]$ ls
Archives        DocumentationCache  Products        iOS Device Logs
DerivedData1        GPUToolsAgent.sock  UserData        iOS DeviceSupport

Then removed the platforms directory and tried again. But the same result. It did generate a new DerivedData folder.

[Fatme]

@jeffswitzer,

xcodebuild -version = Xcode 11.0 Build version 11A420a

Can you try to update to Xcode 11.1, delete DerivedData and platforms folders and execute again tns run ios --emulator?

[jeffswitzer]

@Fatme Found some more information. I have a second nvm environment from before trying to migrate my project to ns 6+ where I think everything is the same except it uses Nativescript 5.4.2 and node 10.12 instead of 10.16. Using that older version, it makes the correct build instead of Build. The tns run ios --emulator output also says "You are using the Legacy Workflow." Here are version params you asked for earlier from this other nvm environment.

(base) [npn@on-campus ios (develop)]$ nvm use 10.12
Now using node v10.12.0 (npm v6.9.0)
(base) [npn@on-campus ios (develop)]$ tns --version
5.4.2
(base) [npn@on-campus ios (develop)]$ pod --version
Ignoring ffi-1.9.18 because its extensions are not built.  Try: gem pristine ffi --version 1.9.18
1.5.3
(base) [npn@on-campus ios (develop)]$ xcodebuild -version
Xcode 11.0
Build version 11A420a

[jeffswitzer]

@Fatme also I can try the 11.1 update, but it probably won't be today as I need to hunt for some disk space to reclaim before it lets me install the update. Apparently 11g free isn't enough. Also seems unlikely that an Xcode update will fix it in light of ns 5.4.2 writing the correct build path?

[Fatme]

Hey @jeffswitzer,

Also seems unlikely that an Xcode update will fix it in light of ns 5.4.2 writing the correct build path?

That's true. When investigating the issue, we found a difference in the arguments passed to xcodebuild from CLI 6.0.0 and CLI 5.4.0. Most probably that difference is not causing the current issue with Build directory. However, we've decided to fix the problem and the fix is already merged in next version of CLI. Could you try the following steps and update us back:

1. npm i nativescript@next -g
2. Update Xcode to 11.1
3. Delete DerivedData and platforms folders
4. tns run ios --emulator

I am having a similar issue (for release builds only) on a mac both with NS 6.1 & 6.2:

Project successfully built.
The build result is located at: /Users/joni/<myapp>/nativescript/platforms/ios/build/Release-iphoneos/nativescript.ipa

 An error was encountered processing the command (domain=NSPOSIXErrorDomain, code=2):

The build process does create an IPA file of ~43M in: ./platforms/ios/build/Release-iphoneos/myapp.ipa

However ./platforms/ios/build/Release-iphoneos/myapp.app is linked to a non-existing file:

$ ls -al platforms/ios/build/Release-iphoneos/nativescript.app

The following dir does exist: but does not contain a dir called InstallationBuildProductsLocation:

/Users/jonathansalomon/Library/Developer/Xcode/DerivedData/nativescript-fueylrwznjovxgbtjkbkccnootyu/Build/Intermediates.noindex/ArchiveIntermediates/nativescript

This location does contain a dir called BuildProductsPath but it is empty after the build.

Note my NS project dir is called nativescript because I have both the firebase and nativescript proejcts in one git repo.
