I’m working with flutter, and I want to install pod, so I’ve run the command pod install in the ios folder of flutter project, and this error occurred:
backendless_sdk does not specify a Swift version and none of the targets (Runner ) integrating it have the SWIFT_VERSION attribute set. Please contact the author or set the SWIFT_VERSION attribute in at least one of the targets that integrate this pod.
Any help?
Hi @adel_kasno
Please specify what version of backendless_sdk flutter plugin do you use.

Hi @Maksym_Khobotin2
I cannot reproduce this issue but I found out that this is a common problem for all Flutter plugins:

Hi,
I’m struggling since the last few days to understand how I can build or u… se Flutter Platform channel plugins that are written in Swift for the iOS part.
To my understanding plugins should not force you to set « use_frameworks! » in your PodFile, because, well, that’s make for example firebase_messaging not working (because this plugin force to comment use_frameworks).
So I try to create a plug-in by my own with the Flutter CLI :
`flutter create —template=plugins -ios-language swift sample`
The project is generated with the use_frameworks! In PodFile who makes it functionnal but incompatible with most from the start.
I’m not an CocoaPods expert but is it still required for Swift Library to use this flag ? I thought that starting at [Cocoapod 1.5](http://blog.cocoapods.org/CocoaPods-1.5.0/) you could remove the flag. But that’s not working at all.
So is it possible to make Flutter Swift plugins who works with firebase plugins ?
If so, can you point me to this direction ? Should the cli create command need to be updated to provide from the start the "good" example project ?
If making swift plugins working with "first party" plugins is not possible, is it not wiser to remove the ability to create swift plugins since this is not "future proof" and can produce some awkward ecosystem of plugins.
Sorry in advance if what I said is not really relevant, I'm trying to understand "the right way" to make iOS plugins...in Swift (Objective-C is not my cup of tea)
## Steps to Reproduce
Create a new Flutter plugin project :
1. `flutter create --template=plugin -i swift sample`
2. In sample/example/ios/Podfile, Comment `use_frameworks!`
3. In sample/example run `flutter run` on iOS emulator
4.
```
fatal error: 'sample/sample-Swift.h' file not found
#import <sample/sample-Swift.h>
```
