Trouble integrating Swift plugin

[AndrewPetrovics]

Couldn't integrate plugin into my Flutter project. I believe the problem has to do with the note mentioned in the readme.

After adding the package to .yaml...

First error:

The “Swift Language Version” (SWIFT_VERSION) build setting must be set to a supported value for targets which use Swift...

Then, I added the following to Podfile...

post_install do |installer|
  installer.pods_project.targets.each do |target|
    target.build_configurations.each do |config|
      config.build_settings['SWIFT_VERSION'] = '3.2'
    end
  end
end

Next error:

/Users/andrew/dev/Pointz/Frontend/ios/Pods/Headers/Public/beacons/BeaconsPlugin.h:1:9: error: 'Flutter/Flutter.h' file not found
    #import <Flutter/Flutter.h>

Then, I added the following to Podfile...

use_frameworks!

and

pre_install do |installer|
 Pod::Installer::Xcode::TargetValidator.send(:define_method,:verify_no_static_framework_transitive_dependencies) {}
end

and

post_install do |installer|
  installer.pods_project.targets.each do |target|
    target.headers_build_phase.files.each do |file|
      file.settings = { 'ATTRIBUTES' => ['Public'] }
    end
  end
end

and then, I deleted Podfile.lock, /ios/Pods and ran flutter clean and got the following error:

Warning: Multiple build commands for output file /Users/andrew/dev/Pointz/Frontend/build/ios/Debug-iphoneos/BoringSSL/openssl.framework/Headers/x509.h

            ^~~~~~~~~~~~~~

Could not build the precompiled application for the device.

I've tried a bunch of other stuff as well, but no dice.

Here's my flutter doctor -v output:

I could not reproduce the issue, both on latest master and beta channels.

I followed the instruction from https://github.com/flutter/flutter/issues/16049#issuecomment-382629492

flutter create --template=app test
cd test
flutter run => fails

In ios/Podfile, I added:

• use_frameworks!
• config.build_settings['SWIFT_VERSION'] = '3.2'

rm ios/Podfile.lock
flutter run => success

What's your Cocoapods version? From my understanding, this workaround works on 1.5+

pod --version

Took some finagling, but got it working.

Testing functionality now...

@AndrewPetrovics how did you get it working? I have a similar issue on a non-Flutter project.

Having the same issue on the newest version of flutter and of beacons. Was there ever a fix for this?
