When running in Xcode 15.3 getting Incompatible function pointer types passing 'YGSize (...)' exception

[alex-mironov]

Bug report

I've updated to the most recent Xcode 15.3 and build started to fail with:

Incompatible function pointer types passing 'YGSize (YGNodeRef, float, YGMeasureMode, float, YGMeasureMode)' (aka 'struct YGSize (struct YGNode *, float, enum YGMeasureMode, float, enum YGMeasureMode)') to parameter of type 'YGMeasureFunc' (aka 'struct YGSize (*)(const struct YGNode *, float, enum YGMeasureMode, float, enum YGMeasureMode)')

Any idea what can be wrong with it?

Getting the issue

    "react-native": "0.73.1",
    "@react-native-community/datetimepicker": "^7.6.2",

[sbeigel]

Same, I changed YGNodeRef to YGNodeConstRef in RNDateTimePickerShadowView.m line 44 (in function RNDateTimePickerShadowViewMeasure) and everything seems back to normal :)

[chsdwn]

Same, I changed YGNodeRef to YGNodeConstRef in RNDateTimePickerShadowView.m line 44 (in function RNDateTimePickerShadowViewMeasure) and everything seems back to normal :)

It fixed my build error issue too. Thank you.

It 's same issue.

[david98]

The solution proposed by @sbeigel was indeed correct, but I kept getting an error at line 4 about "an expected expression". Turns out some weird whitespace character was used, I don't know if that was my fault or what...

EDIT: thanks to @phicoder for the suggestion (my bad for being kinda hasty), the issue was indeed on my end; after reinstalling and rebuilding this is the working patch.

[phicoder]

@david98 for me the proposed solution by @sbeigel was sufficient. I think the error at line 4 might have been on your end. Try to reinstall the package, implement the suggested solution and build again to avoid any confusion.

[fnazarios]

Same here. The workaround fixed the compilation error. Any clue when this will be released?

[hereusmizo]

Same, I changed YGNodeRef to YGNodeConstRef in RNDateTimePickerShadowView.m line 44 (in function RNDateTimePickerShadowViewMeasure) and everything seems back to normal :)

Thank you so much. You save my day.

[mfrfinbox]

I am having the same issue! Changing to YGNodeConstRef fixed the problem, I would love this to be fixed soon! Thanks a lot

[cblaze22]

Please fix.

[therbta]

Same, I changed YGNodeRef to YGNodeConstRef in RNDateTimePickerShadowView.m line 44 (in function RNDateTimePickerShadowViewMeasure) and everything seems back to normal :)

this did work! Thank you.

[mpho-ppm]

Got the same issue on Expo

[mphill]

@mpho-ppm the fix works on Expo too (dev client builds)

Just go to node_modules/@react-native-community/datetimepicker/ios and edit line 44. expo run:<platform> will work again.

This is a hack workaround until a fix is released. If you restore modules this will be overwritten.

[bitcrumb]

@mphill The patch-package library is an excellent way of temporarily patching these kind of issues.

Here's a patch file that I already prepared:
@react-native-community+datetimepicker+7.6.2.patch

In our projects we typically keep these in a patches/ folder with a README.md inside that documents each patch with a link to the related issue(s).

I can really recommend this approach (much easier than having to fork as well).

[mphill]

@bitcrumb nice! EAS build servers are still working because they are not using Xcode 15.3, but we may have to do this if they upgrade. Thanks for sharing this pearl.

[MariuzM]

Same for me, happens when i do local dev expo run:ios and eas build

This worked thank you

Same, I changed YGNodeRef to YGNodeConstRef in RNDateTimePickerShadowView.m line 44 (in function RNDateTimePickerShadowViewMeasure) and everything seems back to normal :)

[MariuzM]

But i did notice when running eas build locally im getting this issue.

[aleksandar-zoric-workvivo]

Can anyone confirm applying the fix above by @sbeigel breaks it on previous versions of Xcode? i.e. is this specific to 15.3?

[araphiel-nf]

But i did notice when running eas build locally im getting this issue.

The fix detailed in this thread is only applicable to React Native 0.73 as this is when Yoga was updated.

https://github.com/facebook/react-native/blob/v0.73.6/packages/react-native/ReactCommon/yoga/yoga/Yoga.h#L32-L37

[MariuzM]

But i did notice when running eas build locally im getting this issue.

The fix detailed in this thread is only applicable to React Native 0.73+

I'm on "react-native": "0.73.4"

[araphiel-nf]

Seems like the patch isn't being applied.

I'd recommend checking that:

• your post installs script is being executed
• your build server isn't pulling from a cache

[johnnyxbell]

Do we have an ETA on a fix? I use expo and I locally build the the apps and it's been failing.

same for me, so I restarted my Mac, it worked.

#868 (comment)

you created a patch? worked for me after i did.

[AngrySquirrell]

Hey, I have the same issue but the fix doesn't work for me... I changed the type of the node variable to the YGNodeConstRef as advised but the error keeps reappearing

[marcelwinter04]

I think you need to create a patch from the package. Because otherwise '''eas build''' just pulls the current package from npm.

Upgrading to v7.6.3 worked for me

My package versions

"@react-native-community/datetimepicker": "7.6.3"
"react-native": "0.73.6",
"expo": "~50.0.15",

If you receive this error when after running npx expo run:ios .

❌ error: Sandbox: bash(27359) deny(1) file-read-data / ...

Just set User Script Sandboxing to No on Build Settings > Build Options

[radulescuandrew]

Confirm upgrading to 7.6.3 fixed it. Cheers 🍻

[pavlo-tretiak]

Upgraded to 7.6.4.

Now it's vice versa 😅 🤡

incompatible function pointer types passing 'YGSize (YGNodeConstRef, float, YGMeasureMode, float, YGMeasureMode)' (aka 'struct YGSize (const struct YGNode *, float, enum YGMeasureMode, float, enum YGMeasureMode)') to parameter of type 'YGMeasureFunc' (aka 'struct YGSize (*)(struct YGNode *, float, enum YGMeasureMode, float, enum YGMeasureMode)') [-Wincompatible-function-pointer-types]

Changing YGNodeConstRef back to YGNodeRef fixed the problem.

[aaparicio87]

Same error that @pavlo-tretiak
version 7.7.0
`incompatible function pointer types passing 'YGSize (YGNodeConstRef, float, YGMeasureMode, float, YGMeasureMode)' (aka 'struct YGSize (const struct YGNode , float, enum YGMeasureMode, float, enum YGMeasureMode)') to parameter of type 'YGMeasureFunc' (aka 'struct YGSize ()(struct YGNode *, float, enum YGMeasureMode, float, enum YGMeasureMode)') [-Wincompatible-function-pointer-types]

YGNodeSetMeasureFunc(self.yogaNode, RNDateTimePickerShadowViewMeasure);`

Any solution?

[kodaraj]

Just upgrading to 7.7.0 worked for me.

eas build -p ios --local

"expo": "^50.0.14",
"@react-native-community/datetimepicker": "^7.7.0",
"react-native": "0.73.6",

[aaparicio87]

Seems to be a problem of platform, because I have React Native 0.72

[christophby]

Issue still exists:

• react-native 0.72.13
• @react-native-community/datetimepicker 7.7.0

[tylim88]

@react-native-community/datetimepicker: 8.0.0
react-native: 0.73.6

works

[GerardjRincon]

Same, I changed YGNodeRef to YGNodeConstRef in RNDateTimePickerShadowView.m line 44 (in function RNDateTimePickerShadowViewMeasure) and everything seems back to normal :)

In my case it was the opposite I had to change YGNodeRef to YGNodeRef

[OguzEkinci]

Upgraded to 7.6.4.

Now it's vice versa 😅 🤡

incompatible function pointer types passing 'YGSize (YGNodeConstRef, float, YGMeasureMode, float, YGMeasureMode)' (aka 'struct YGSize (const struct YGNode *, float, enum YGMeasureMode, float, enum YGMeasureMode)') to parameter of type 'YGMeasureFunc' (aka 'struct YGSize (*)(struct YGNode *, float, enum YGMeasureMode, float, enum YGMeasureMode)') [-Wincompatible-function-pointer-types]

Changing YGNodeConstRef back to YGNodeRef fixed the problem.

ahahaha lol, it's working really v8.0

[sinonodd]

I faced the same issue

Updated from "@react-native-community/datetimepicker": "7.6.1" to "@react-native-community/datetimepicker": "7.6.3"
and it worked 🪄

[friederbluemle]

I just ran into this issue as well, and after some trial and error, I can confirm 7.6.3+ is breaking RN 0.72 (and below?), while 7.6.2 still works. It can be traced back to #868, merged and released with v7.6.3 on March 18, 2024.
As @araphiel-nf noted above, this should probably have been considered a breaking change (i.e. major semver). But since the issue was at least in part affected by an "external" tool update (Xcode 15.3), it's a tricky situation. If possible, it should have been implemented in some backwards compatible way, and released as a follow up patch release (e.g. 7.6.5 and 7.7.1).
Currently, the major version 7 series appears to be partially compatible with RN <=0.72 and partially with RN 0.73+:

react-native	datetimepicker
<=0.72	<=7.6.2
0.73+	7.6.3+

[blodyle]

Hi all 👋
It seems there was some sort of regression from a couple months back since right now I had to change from YGNodeConstRef to YGNodeRef which is the exact opposite solution from this one (#866 (comment))

Is there any way you could reopen this issue (or create another one) in order to address this? Thanks!

Upgrading to version 7.6.3 solved my issue on expo.dev

[AliHassan5927]

When we change ⁠ YGNodeRef ⁠ to ⁠ YGNodeConstRef ⁠ in RNDateTimePickerShadowView.m line 44 and run the app, it's working fine but when we run 'pod install', we have to update again RNDateTimePickerShadowView.m. To fix this issue, we will create a patch for ⁠ @react-native-community/datetimepicker ⁠.

This solution worked for me:

⁠react-native: ^0.71.7
⁠@react-native-community/datetimepicker: ^8.0.0

Step-1.⁠ ⁠npm i patch-package.

Step-2.⁠ ⁠add a new script in ⁠ package.json ⁠:

"scripts": {
"postinstall": "patch-package"
}

Step-3.⁠ ⁠Go to ⁠ node_modules/@react-native-community/datetimepicker/ios/RNDateTimePickerShadowView.m ⁠, replace ⁠ YGNodeConstRef ⁠ with ⁠ YGNodeRef ⁠ in ⁠ RNDateTimePickerShadowView.m ⁠ line 44.

Step-4.⁠ ⁠Run command ⁠ npx patch-package @react-native-community/datetimepicker ⁠

[Devdannnny]

I faced the same issue

Updated from "@react-native-community/datetimepicker": "7.6.1" to "@react-native-community/datetimepicker": "7.6.3" and it worked 🪄

This works!!!

[harshithvemulas]

I just ran into this issue as well, and after some trial and error, I can confirm 7.6.3+ is breaking RN 0.72 (and below?), while 7.6.2 still works.

This worked for me, I was using RN 0.72 downgraded datetimepicker to 7.6.2 from 7.6.4 and it worked

[imamrobani]

Same, I changed YGNodeRef to YGNodeConstRef in RNDateTimePickerShadowView.m line 44 (in function RNDateTimePickerShadowViewMeasure) and everything seems back to normal :)

So I changed back to YGNodeRef and it works.

I think this issue back in version 8.0.1

"react-native": "0.72.14",
"@react-native-community/datetimepicker": "^8.0.1",
Xcode: 15.4

Works for me to change back to YGNodeRef

[shivanip-iprogrammer]

YGNodeConstRef

same issue, still facing

[Rajaram10]

I am using "react-native": "0.71.7",
"@react-native-community/datetimepicker": "7.6.3",
Xcode: 15.4,
and i went with "YGNodeRef" instead of "YGNodeConstRef"
I am able to publish the app.

[KubilayKartega]

whelp its broken again. I suspect Xcode 15.4 update. Using
"react-native": "0.72.10",
tried both
"@react-native-community/datetimepicker": "^8.1.1",
and
"@react-native-community/datetimepicker": "^8.0.1",

Incompatible function pointer types passing 'YGSize (YGNodeConstRef, float, YGMeasureMode, float, YGMeasureMode)' (aka 'struct YGSize (const struct YGNode , float, enum YGMeasureMode, float, enum YGMeasureMode)') to parameter of type 'YGMeasureFunc' (aka 'struct YGSize ()(struct YGNode *, float, enum YGMeasureMode, float, enum YGMeasureMode)')

when building

[psychoz971]

@KubilayKartega I have the same issue. It doesn't work since Xcode 15.4 update :( with "@react-native-community/datetimepicker": "^8.1.1"

[astmuhammadadil]

Same, I changed YGNodeRef to YGNodeConstRef in RNDateTimePickerShadowView.m line 44 (in function RNDateTimePickerShadowViewMeasure) and everything seems back to normal :)

I did the opposite of this, and it resolved my issue.

[kaushalpanchal123]

Same, I changed YGNodeRef to YGNodeConstRef in RNDateTimePickerShadowView.m line 44 (in function RNDateTimePickerShadowViewMeasure) and everything seems back to normal :)

it's worked like charm!

[usmanabid94]

This worked for me I have used the latest 8.2.0 and still faced the same issue with it.

Same, I changed YGNodeRef to YGNodeConstRef in RNDateTimePickerShadowView.m line 44 (in function RNDateTimePickerShadowViewMeasure) and everything seems back to normal :)

I did the opposite of this, and it resolved my issue.

[Gentlekboy]

Same, I changed YGNodeRef to YGNodeConstRef in RNDateTimePickerShadowView.m line 44 (in function RNDateTimePickerShadowViewMeasure) and everything seems back to normal :)

The opposite worked for me. I changed YGNodeConstRef to YGNodeRef.

[DusanDigitalWare]

Any update on this, is the only solution to use patch-package?
