My app was working great until about two hours ago when I got a link error regarding an unsafe mutable addressor.
What I've tried:
Clean and build, deintegrated and reinstalled my cocoapods, deleted derived data, restart XCode, restart Mac
None of this has helped. Can anyone tell me from the error text what the problem is?

I figured it out. I had a double instantiation of a variable. Once I deleted that, the app compiled normally.

I tried every solution like upgraded flutter, restart system, delete derived data, uninstall and reinstall pods, remove other flags in target but same error.
here is all log

Tried to use OpenCV library in swift.
The library forces me to implement changes below :
Otherwise, without those changes i get an error:
Also in this App i want the user to pick an image from phone's gallery. To handle it, I'm using PHPicker.
However, with Excluded Architectures set, I'm not able to pick any image from the gallery, there's buch of errors/warnings in Terminal.
Without Excluded Architectures app will crash with Error as at second screen.
Any ideas or tips ?

Text formating of error is not my fault!
so, building for iOS Simulator, but linking in object file built for iOS, for architecture arm64 I guess that means you need the library built for the simulator, not for the actual target device.
It works when you try compile it, using real iPhone/iPad

So I post this question to ask how to solve this issue and what is the main reason for this error. Thank you so much!!!!
You need to delete your DerivedData project folder:
'Xcode' -> 'Preferences' -> 'Locations' tab -> At 'Derived Data' click the open icon and delete the folder in Finder.
Then Clean build folder. Also make sure you have xcworkspace open not xcproject and also try pod deintegrate and pod install prior to this from inside the iOS dir of the project.
I am getting this error while trying to build in Xcode. I tried deleting derived data and restarting Xcode but nothing helped.

How can I solve this issue?
I change to master channel.
flutter channel master
then run
flutter upgrade
For people coming here in 2020, I experienced this issue, ran the commands in the answer above (flutter channel master, flutter upgrade), and was then required to manually migrate my Xcode project to still work with the new version of Flutter. Info on that available here: https://flutter.dev/docs/development/ios-project-migration. Hope that can be of some help to someone.
Here's what worked for me:
Delete the ios folder completely
In the terminal, type flutter create .
And then try flutter run or press Play in Android Studio.
Try the following command:
flutter upgrade
I have been trying for hours to fix this build error.
None of the advice from the dozens of threads I've read has fixed this error. What can I do?
