Cant build since Xcode 10

[larssn]

Did you verify this is a real problem by searching the [NativeScript Forum]

Found a related issue: https://stackoverflow.com/questions/52340033/xcodebuild-failed-exit-code-65-ios

Tell us about the problem

After updating to Xcode 10 (today), my tns run ios --log trace fails on the xcode build step with:

(I've anonymized the output)

I have the entire trace log output if anyone needs it.

Not sure if the error could be related to having the xcode update run in the background, while xcodebuild being used from the commandline. I've tried doing a tns update, but it didn't fix the issue.

Not sure how to recreate if it doesn't fail on a fresh upgrade of xcode 10 in your end.

[larssn]

Seems to be related to the new build system in Xcode 10. A temporary workaround seems to be switching to the legacy build system by going to (in Xcode) File -> Workspace Settings -> Build System -> Legacy Build System. But compiling with the CLI still doesnt work.

[mbektchiev]

Hi @larssn, looking at this error I can see that there are multiple TNSCore.frameworks in you node_modules directory:

error: Multiple commands produce '<my-user>/Library/Developer/Xcode/DerivedData/ourApp-axpwxekjlqemgxhcqrekmksxyout/Build/Intermediates.noindex/ArchiveIntermediates/ourApp/InstallationBuildProductsLocation/Applications/ourApp.app/Frameworks/TNSCore.framework/TNSCore':
1) Target 'ourApp' has copy command from './node_modules/nativescript-ui-core/platforms/ios/TNSCore.framework' to '<my-user>/Library/Developer/Xcode/DerivedData/ourApp-axpwxekjlqemgxhcqrekmksxyout/Build/Intermediates.noindex/ArchiveIntermediates/ourApp/InstallationBuildProductsLocation/Applications/ourApp.app/Frameworks/TNSCore.framework'
2) Target 'ourApp' has copy command from './node_modules/nativescript-ui-listview/node_modules/nativescript-ui-core/platforms/ios/TNSCore.framework' to '<my-user>/Library/Developer/Xcode/DerivedData/ourApp-axpwxekjlqemgxhcqrekmksxyout/Build/Intermediates.noindex/ArchiveIntermediates/ourApp/InstallationBuildProductsLocation/Applications/ourApp.app/Frameworks/TNSCore.framework'

Probably this is due to the fact that you have different major versions for ListView and SideDrawer:

    "nativescript-ui-listview": "^3.6.1",
    "nativescript-ui-sidedrawer": "~4.2.0"

I suppose that upgrading ListView will fix the error.

[mbektchiev]

It seems that I spoke too fast -- ListView is already the latest but SideDrawer is not. I suggest you upgrade it as well.

[mbektchiev]

Yes, that fixes it. I managed to reproduce the error with your versions, and it got fixed after upgrading. It seems that the old build system has tolerated this inconsistency and has silently selected one of the 2 frameworks, while the new one is stricter and treats this as an error.

[larssn]

Thanks for the snappy response.

While you are correct that the dependency was behind, even bringing it up to v4.3.0 (using tns plugin update didn't fix the issue. Also updated tns-core-modules from 4.2.0 to 4.2.1.
Getting the same errors.

I suspected nativescript-ui-core but doing a npm list nativescript-ui-core doesn't show any version mismatches:

./ourApp
├─┬ nativescript-ui-listview@3.6.1
│ └── nativescript-ui-core@2.0.0 
└─┬ nativescript-ui-sidedrawer@4.3.0
  └── nativescript-ui-core@2.0.0 

Will continue investigating...

[mbektchiev]

I would suggest that you wipe the node_modules directories altogether. Or at least the two nativescript-ui-core dirs. This will make npm install the plugin only once.

The failure continues to occur because you still have two occurrences of the frameworks.

Another alternative is to try and run npm dedupe

[larssn]

Same issue
Have tried various combinations of rm -rf node_modules / npm i and tns update.

The resulting node_modules folder always seem to have a slightly wrong structure.
Again, doing an npm list nativescript-ui-core reveals:

./ourApp/
├─┬ nativescript-ui-listview@3.6.1
│ └── nativescript-ui-core@2.0.0 
└─┬ nativescript-ui-sidedrawer@4.3.0
  └── nativescript-ui-core@2.0.0

So far so good, only one version of nativescript-ui-core.
But when I inspect the folders, they look as following:

./node_modules/nativescript-ui-core
./node_modules/nativescript-ui-listview/node_modules/nativescript-ui-core
./node_modules/nativescript-ui-sidedrawer

So nativescript-ui-listview has it's own node_modules folder, while nativescript-ui-sidedrawer does not, and instead seems to rely on the root level.

Any ideas as to why this happens?

[mbektchiev]

Do you have a package-lock.json? It could be forcing NPM to duplicate the module. Simply delete it if it exists.

[larssn]

nativescript-ui-listview seems to have just been updated to 3.7.0. That, combined with deleting package-lock.json seems to have corrected the node_modules pathing problem, BUT the problem still remains.

As you can see from the above, it's still copying data from two places. Or so it thinks!
I've verified that the node_modules folder is gone from nativescript-ui-listview, and just to be sure, I've done a cd /Users/<my-user>/workspace/<my-company>/<our-app>/node_modules/nativescript-ui-listview/node_modules and the path does not exist anymore.

So I figure it was cached somehow with some kind of tns magic, so I tried removing the related directories from /Users/<my-user>/Library/Developer/Xcode/DerivedData/, but that didn't work either.

Second idea was that even though the files doesn't exist, Xcode will deny any attempt to copy the same framework file? Not sure how to solve that one, if that is the case. I'm new with NativeScript, and I don't know that much yet.

[rosen-vladimirov]

Hey @larssn ,
Have you tried removing your platforms directory and building your project again (after fixing the package-lock.json issue) ?

[larssn]

@rosen-vladimirov It was my impression that tns update did that? I have some custom facebook/google configuration each in platform, that I was hoping to keep. It's no biggy if I lose it though.

[larssn]

No wait, I was thinking about App_Resources. I'll try deleting the platforms.

[larssn]

😂 It works! Deleting the platforms folder did the trick.
Thank you so much guys, for your good ideas. I'd still be fiddling with this otherwise.

Out of curiosity, is there any recommendation on how to manage your dependencies in NS, so stuff like this doesn't happen again? npm will usually add install modules with the caret (minor) ^, while creating a new project will default to tilde (patch) versions ~. I'm thinking that's how the two plugins got out of sync.

[hettiger]

Please reopen the issue @larssn

I found a solution, see the bottom of this comment.

I'm having the same problem described here.

I did execute the following commands:

rm -rf node_modules
rm -rf platforms
rm package-lock.json
npm i
pod repo update
tns run ios

I'm still facing the issue. I will try switching to the Legacy Build System now.

After switching to the Legacy Build System I was not able to build successfully.
I had to execute the erase all contents and settings feature from the iOS Simulator first.

Now I'm able to build using Xcode directly. tns run ios still fails with the following (anonymized) output:

✔ Getting NativeScript components versions information...
✔ Component nativescript has 4.2.4 version and is up to date.
✔ Component tns-core-modules has 4.2.1 version and is up to date.
✖ Component tns-android is not installed.
✔ Component tns-ios has 4.2.0 version and is up to date.

Solution:

I've managed to find the root of all evil:

npm list nativescript-ui-core
├─┬ nativescript-imagepicker@5.0.2
│ └── nativescript-ui-core@1.0.1 
└─┬ nativescript-ui-listview@3.7.0
  └── nativescript-ui-core@2.0.0 

Fix:

tns plugin update nativescript-imagepicker
npm dedupe

Now everything's working like a charm. Even with the new build system.
