Kingfisher: Kingfisher stops the app from archiving on Xcode 13 RC

Duplicated with #1725

As indicated in the Xcode 13 Release Notes:

Known Issues

Swift libraries may fail to build for iOS targets that use armv7. (74120874) Workaround: Increase the platform dependency of the package to v12 or later.

Swift libraries depending on Combine may fail to build for targets including armv7 and i386 architectures. (82183186, 82189214) Workaround: Use an updated version of the library that isn’t impacted (if available) or remove armv7 and i386 support (for example, increase the deployment target of the library to iOS 11 or higher).

Unfortunately Kingfisher falls into this (since it is supporting SwiftUI, which in turn using Combine to manage states).

This is not a thing can be fixed easily in a library like Kingfisher. So please try to upgrade to Kingfisher v7 (and consider to drop support under iOS 12. Here is the migration guide).

Here is an image (from Aug, 2021) that you can use to persuade your boss to drop those old ones:

I am not sure if this “Known Issues” can be fixed by Apple in near future. With the fact that the problem started to be there from Xcode 13 beta 2 to the final release, I doubt whether Apple has any motivation to fix it or mark it as urgent.

If you still need to support older systems (such as iOS 10 or 11), maybe it is a good idea to keep using Xcode 12 for a longer while before Apple fixes it.

TLDR

Determine the latest version you can use by:

If you really have to support from iOS 10 in Xcode 13, and you are not using SwiftUI. Check the workaround here.

Detail for current workaround

For anyone who still needs to use Kingfisher v6 (for supporting iOS 11 UIKit or iOS 13 SwiftUI), but wants to use it in Xcode 13, now there is a compatible branch version6-xcode13. Pointing your dependency of Kingfisher to that branch would help you to avoid this issue.

The only change in that branch, compared to the released 6.3.1, is dropping of iOS 10 for UIKit support. That allows Xcode 13 skip the ARMv7 compilation so it won’t trigger this issue anymore. That branch would exist for at least one year so you can migrate to version 7 eventually.

Again, the deployment increment in Kingfisher v7 (iOS 12 for UIKit, iOS 14 for SwiftUI) is intended and important to provide a correct data model. If you do not need to support older system anymore, it is encouraged to upgrade to the latest version.

Use Xcode 13 Release and drop support under iOS 11 will fix for me. emmmm… Maybe Apple Document made a mistake!

Some project need to modify configuration as follows:

post_install do |pi|
    pi.pods_project.targets.each do |t|
        t.build_configurations.each do |config|
            config.build_settings['IPHONEOS_DEPLOYMENT_TARGET'] = '11.0'
        end
    end
end

Confused behaviour! 😂

We noticed this issue can be fixed by changing Project Format to Xcode 8.0-compatible within iOS 11. And then Architectures became ARCHS_STANDARD_64_BIT, Archiving will not include armv7. But We recommend to set Xcode 12.0-compatible and modify pod target config.build_settings.delete 'IPHONEOS_DEPLOYMENT_TARGET' to inherit project.

Xcode 13.2 was released (as RC although) in which a fix for this is contained. Now even Kingfisher v6 could be used in Xcode 13.2.

Since my min supported iOS version is 13.0. This did the trick for me to fix cocoapods integration:

post_install do |pi|
    pi.pods_project.targets.each do |t|
        t.build_configurations.each do |config|
            config.build_settings['IPHONEOS_DEPLOYMENT_TARGET'] = '13.0'
        end
    end
end

Hi, you can use Xcode 13+ and Kingfisher and iOS 11 (tested) if you will remove pods and install Kingfisher from SPM

Archiving work fine
