seems like image_downloader goes wrong?

ko2ic commented 5 years ago

@doomsdayer image_downloader have been specified Swift Version Language 4. In addition, I confirmed the operation with a library containing sqflite as well as you. The result worked fine.

I think that your app's PodFile is not going well. How about adding the following in your app's Podfile?

post_install do |installer|
    installer.pods_project.targets.each do |target|
        target.build_configurations.each do |config|
            config.build_settings['SWIFT_VERSION'] = '4.0'
        end
    end
end

Please let me know again if the problem is not resolved.Thank you.

lucasjinreal commented 5 years ago

@ko2ic I got same error:

image

it seems your codes contains swift3x, how to migrate it to 4?

ko2ic commented 5 years ago

@jinfagang Thanks for your comment.

Is it an error even if I try the following? https://github.com/ko2ic/image_downloader/issues/9#issuecomment-471186536

lucasjinreal commented 5 years ago

@ko2ic I haven't try that, I am using the newest xcode 10.2, which may need newest swift version.

doomsdayer commented 5 years ago

@ko2ic So I replaced some code in the ios/Podfile ~~post_install do |installer| installer.pods_project.targets.each do |target| target.build_configurations.each do |config| config.build_settings['ENABLE_BITCODE'] = 'NO' end end end~~

to

post_install do |installer| installer.pods_project.targets.each do |target| target.build_configurations.each do |config| config.build_settings['SWIFT_VERSION'] = '4.0' end end end

but still the same

ko2ic commented 5 years ago

@doomsdayer @jinfagang I can not reproduce it, but I fixed it. It may not change, please try v0.11.2.

lucasjinreal commented 5 years ago

@ko2ic Thanks, I will try it tonight, the most likely reason for this maybe I am using the newest version xcode

doomsdayer commented 5 years ago

@ko2ic still the same.... I have created a grand new project and only add the dependence image_downloader and got the same error. I have sent the project to you by mail, could it work well at your environment? My XCode is 10.1

ko2ic commented 5 years ago

@doomsdayer My environment is also Xcode 10.1. It is working. In addition, I use it in multiple projects but it works.

Does it work on the example project?

doomsdayer commented 5 years ago

@doomsdayer My environment is also Xcode 10.1. It is working. In addition, I use it in multiple projects but it works.

Does it work on the example project?

@ko2ic Yes, the example is Ok, and I found there's AppDelegate.swift in your example. But the project I gave you (created by flutter new project wizard) is based on AppDelegate.h and AppDelegate.m, so there must be some issue of incompatible.

Could it be fixed?

doomsdayer commented 5 years ago

@ko2ic I found a solution for this issue, but not perfect.

  1. Add use_frameworks! in the Podfile
  2. Open ios project with XCode, and create a swift code file in the Runner directory
  3. delete the swift file just created

Then the project can run on ios emulator by Android Studio with Flutter plugin, But can't run by XCode, error msg is

could not find included file 'Pods/Target Support Files/Pods-Runner/Pods-Runner.debug.xcconfig' in search paths (in target 'Runner')

ko2ic commented 5 years ago

@doomsdayer Oh, it was that situation. This problem happens with all Swift plugins. https://github.com/flutter/flutter/issues/25676

You are almost right. It seems to work with the following

  1. Bridging Header must be created. Open the project with XCode. Then choose File -> New -> File -> Swift File. A dialog will be displayed when creating the swift file(Since this file is deleted, any name can be used.). XCode will ask you if you wish to create Bridging Header, click yes.
  2. Make sure you have use_frameworks! in the Runner block, in ios/Podfile。
  3. Make sure you have SWIFT_VERSION 4.2 selected in you XCode -> Build Settings
  4. Do flutter clean
  5. Go to your ios folder, delete Podfile.lock and Pods folder and then execute pod install --repo-update

Thank you for giving detailed report!!

lucasjinreal commented 5 years ago

@ko2ic Does it will update this package release? I am pretty new in iOS development, it seems not convenient to use compare with other flutter packages

ko2ic commented 5 years ago

@jinfagang Does it mean to rewrite to objective-c? There is no plan to rewrite it now. Since this is a problem with flutter, there is no problem if the flutter side fix.

In addition, If you select swift when creating the app, it will work without doing anything.

it seems not convenient to use compare with other flutter packages

Plugins created with swift all have the same problem.

lucasjinreal commented 5 years ago

@ko2ic OK, now I understand it

ko2ic commented 5 years ago

@doomsdayer If you have not worked yet, please refer to the following. https://github.com/ko2ic/sample_image_downloder_objc

It is a sample of AppDelegate made with Objective-C.

ko2ic commented 5 years ago

I'll fix it below so close it.
https://github.com/ko2ic/image_downloader/wiki#your-appdelegate-is-the-case-of-objective-c

If the same problem occurs, please set up another issue.

dingjianjaja commented 5 years ago

The easiest way to solve this problem is to create a new. swift file under the iOS file.

HardikDG commented 5 years ago

@doomsdayer Oh, it was that situation. This problem happens with all Swift plugins. flutter/flutter#25676

You are almost right. It seems to work with the following

  1. Bridging Header must be created. Open the project with XCode. Then choose File -> New -> File -> Swift File. A dialog will be displayed when creating the swift file(Since this file is deleted, any name can be used.). XCode will ask you if you wish to create Bridging Header, click yes.
  2. Make sure you have use_frameworks! in the Runner block, in ios/Podfile。
  3. Make sure you have SWIFT_VERSION 4.2 selected in you XCode -> Build Settings
  4. Do flutter clean
  5. Go to your ios folder, delete Podfile.lock and Pods folder and then execute pod install --repo-update

Thank you for giving detailed report!!

As Swift 5 is there for some time. Will there any issue if we have SWIFT_VERSION 5.0 in the Xcode?

redent commented 4 years ago

Just an update for future googlers, this is what I do to manually set the swift version of legacy CocoaPods libraries:

pre_install do |installer|
  installer.analysis_result.specifications.each do |s|
    if s.name == 'YOUR_POD_NAME_HERE'
      s.swift_version = '4.2'
    end
  end
end
kasp1 commented 4 years ago

@redent Where exactly do you put this?

danydev commented 4 years ago

@kasp1 just in your Podfile, any position is good, so can be at the lower end.

kasp1 commented 4 years ago

@danydev Thanks, figured it out. For some reason there was no Podfile in my project so I had to put it together.

And then I found these templates... https://github.com/flutter/flutter/tree/master/packages/flutter_tools/templates/cocoapods

lxcyha commented 4 years ago

@ko2ic Hello, What if pod install --repo-update running slowly? Can I ignore this command? And if I finished it and my other projects have the same issue should I run it again?

jaysworldofcode commented 3 years ago

Fix mine by going to ios/Podfile.... then add ENV['SWIFT_VERSION'] = '5' at the top of your podfile.

Update: Also adding this use_frameworks! # required by HexColor below the swift version

tushardubey121 commented 3 years ago

Just add a few amazing lines in the plugin amazon_s3_cognito.podspec file

  1. Add s.swift_version = '5.0'
  2. Change the s.ios.deployment_target = '11.0' according to your app support
