@shravanispr Thanks for reporting, the following like it could be root of your issue.

/Users/user/projects/project/ios/Pods/Pods.xcodeproj: warning: The iOS deployment target 'IPHONEOS_DEPLOYMENT_TARGET'
is set to 8.0, but the range of supported deployment target versions is 9.0 to 15.2.99. (in target 'leveldb-library' from
project 'Pods')

Could you check the top of your Podfile to make sure you have the following:

# Uncomment this line to define a global platform for your project
platform :ios, '9.0'

For extra context, this is step 3.8 in the OneSignal Flutter setup guide.

If above does not help could you let us know the following:

1. Does this happen with a new Flutter project?
2. Do you have any other plugins / SDK in your project? If so please list them and your versions.
3. Please include the full contains of your Podfile.

[shravanispr]

@jkasten2 Global Platform for the project is higher than '9.0'

Yes, it is happening with the new project

Steps to Reproduce

1. Create a new flutter project with swift as IOS language
2. Add onesignal_flutter: ^3.3.0 under dependencies
3. Add OneSignalNotificationServiceExtension to the target as per the instruction in the official docs (https://documentation.onesignal.com/docs/flutter-sdk-setup) using swift language

@shravanispr Is this still happening? I believe there was an issue with one of the iOS native podspecs that allowed the version to be lower than 9, but that has been fixed.

[ynmain]

This problem is still occurring. Happened with version 3.4.0, not with 3.3.2. It's a problem that needs to be resolved quickly.

[Jeonguk-ninehire]

I solved this problem by adding Run script in Extension target build phase.
Copied from Runner target build phase and put it on same sequence. /bin/sh "$FLUTTER_ROOT/packages/flutter_tools/bin/xcode_backend.sh" build

Thank you so much!

[jonaheapen98]

Still facing this issue with the above fix. Has anyone resolved this? OneSignal version - 5.0.4

[emawby]

@jonaheapen98 This issue is a symptom of Cocoapods installation going wrong. Were you able to solve it?

[joaoarmando]

Any updates? I'm facing the same issue...

[lakshydeep-14]

There is no issue while implementing in Android. Facing issue while implementing in iOS. Followed the official docs. Did all but stuck on this 👇 #import <Flutter/Flutter.h> not found Any solution?

[ShvetsovZE]

Same here, following the official documentation. Tried multiple times and every time ending up with

Error (Xcode): 'Flutter/Flutter.h' file not found

Looks like a common issue, @jkasten2 if there is any plan for the OneSignal team to fix or it's not a priority? Flutter package -> onesignal_flutter: ^5.0.4

[ShvetsovZE]

I just updated the package to 5.1.0 and the issue is still present. @Jeonguk-ninehire Could you send a screenshot of your solution please, as when i try to follow it, the build fails bout not being able to find a directory

[Jeonguk-ninehire]

@ShvetsovZE Here's my extension build phase run script and my OneSignal package version is 5.0.4 now. I wish it could help you.

[ShvetsovZE]

hey @Jeonguk-ninehire , thanks for coming back to me. It fixes the original issue, but another pops up now.

`Could not build the precompiled application for the device. Error (Xcode): Cycle inside Runner; building could produce unreliable results.

I'm very new to flutter and ios, do you know what might caused it?

[arwysyah]

I solved the problem by copy Run Script in Build Phases from Runner to OneSignalNotificationServiceExtension Build Phases and then you will get an error Error (Xcode): Sandbox: rsync.samba(34407) deny(1) file-write-create... , you just need to set "User Script Sandboxing" in your "Build Settings" false onesignal_flutter: ^5.1.2 Xcode : 15.1

NOTE : if you get this error Could not build the precompiled application for the device. Error (Xcode): Cycle inside Runner; building could produce unreliable results. Cycle details: → Target 'Runner': CodeSign /Users/user/Documents/development/repos/finelly-app/src/finelly/build/ios/Debug-qa-iphoneos/Runner.app ○ That command depends on command in Target 'Runner': script phase “[CP] Embed Pods Frameworks”

move your Embedded Foundation Extension above your Run Script in Build Phases

hope it help
