Project Builds and Runs, but does not Archive - ios

Question

I have a project which builds and runs fine on the simulator and device, but fails when archiving.
The project is very old, but I have created a separate component which I have added in the workspace.
The main project is written in Objective-C, the new project is written in Swift 4. The project also uses CocoaPods and also includes another subproject written in Swift 3.2
There are various errors which all boil down to the same thing, the sub project is not producing any output when it is compiled. OR it is just not compiled. I see no errors in the code itself, just when trying to reference it:
//1
error: /Users/<user>/Library/Developer/Xcode/DerivedData/<id>/Build/Intermediates.noindex/ArchiveIntermediates/<app name>/BuildProductsPath/Release-iphoneos/Framework.framework: No such file or directory`
//2
Signing Identity: "iPhone Developer: <redacted>“
/Users/<user>/Library/Developer/Xcode/DerivedData/<id>/Build/Intermediates.noindex/ ArchiveIntermediates/<app name>/InstallationBuildProductsLocation/Applications/<app name>/Frameworks/<framework>.framework: No such file or directory
Command /usr/bin/codesign failed with exit code 1
//3
#import ModuleName;
Module ‘ModuleName’ not found
Here’s what I’ve tried:
Clear derived data
Restart Mac
Add $(SRCROOT) to Main Target > Build Settings > Framework Search Paths > Release
Confirmed project is present in Embedded Binaries
Confirmed project is present in Linked Frameworks and Libraries
Removing and re-adding project to embedded binaries and frameworks and libraries
Removing the import declaration
I am opening the workspace and not the project
Skip install set to YES in Subproject build settings
Comparing build settings from the working sub project with the failing one (they are the same)
Running pod update
Changing Always Embed Standard Swift Libraries makes no difference either way
Other notes:
In /Users/<user>/Library/Developer/Xcode/DerivedData/<id>/Build/ Intermediates.noindex/ArchiveIntermediates/<app name>/ InstallationBuildProductsLocation/Applications/<app name>.app/Frameworks/ there is a .framework file for the other sub project and all the pods, but not for this one
In podfile, use_frameworks! is present
Update:
After running an archive today I am only seeing the error:
Module 'ModuleName' not found
The other errors are gone

Answer 1

The issue was to do with the iOS Deployment Target setting:
The main project: iOS 10
Sub project: iOS 11
In Debug it is building only for the current architecture, in Release it builds for all. Obvious once you know.
Setting the sub project to build for iOS 10 fixed the issue.
The most frustrating part: I double checked the build log and it doesn't mention the version issue anywhere :(

Answer 2

It's impossible to tell what exactly causing it to fail archiving. BUT I'm pretty sure I can give you the correct direction =]
Running on simulator or even a real device - compiles the project for "Debug"
Archiving tough, compiles for "Release"
I bet that if you set that running on simulator will compile on Release mode, it will fail!
Check it!!
If I correct you just need to set some of the Build Settings for Release to match Debug
My first guess is: All the search paths (Framework search path, and Runpath search path)
I saw a similar behavior here
I got it to archive after all.
It looked like the SDK-Project was missing a build configuration
Adhoc. Which Project used to archive the project for a specific build
scheme. I think the compiler was looking for modules in the
$(CONFIGURATION)$(EFFECTIVE_PLATFORM_NAME) path

Answer 3

I was having this error, and while my deployment targets did not match, that wasn't actually the fix for me. I had added a new build configuration that I was trying to use for my archive, but I forgot to run pod install after adding it. After running pod install, I was able to archive my app just fine, even though the deployment targets for some of the Pods are iOS 10 while the main app target is iOS 11.

Answer 4

Might be not relevant to you, but helpful to others:
If you using multi-modular SwiftPM-based architecture, then you should read errors carefully and find out if some of your package targets import some other one in sources without integrating it in the Package.swift file. In this case, even the release build will resolve dependencies somehow and succeed if some other package contains your dependency, but the archive will fail.
Package graph examples:
––––––––––
App
├– PackageA [target1(import PackageC.target1)]
└– PackageB [target1(import PackageC.target1)]
└– PackageC [target1]
👆 Builds with success, archives with errors (Can't find module PackageC.target1 in PackageA.target1)
––––––––––
App

└– PackageB [target1(import PackageC.target1)]
└– PackageC [target1]
👆 Builds and archives with success

Cocoapods and Architecture settings
I had a Podfile that set EXCLUDED_ARCHS to arm64 in a post-install script and this was consistent with my main target. This setting was ok for building on Debug mode (x86_64) but didn't work for release building (Archives). I realised the script set EXCLUDED_ARCHS for the Pod targets even on physical devices (Any iOS SDK) rather than only on Simulators.
Steps
I ran pod deintegrate.
I deleted Derived Data.
I deleted Podfile.lock (now we have a fresh start).
I updated the Podfile iOS version to be the lowest supported version in each Pod.
Refactor EXCLUDED_ARCHS script.
Refactoring EXCLUDED_ARCHS script
I refactored:
config.build_settings['EXCLUDED_ARCHS'] = 'arm64'
from the Podfile post-install script to the following:
post_install do |installer|
installer.pods_project.targets.each do |target|
target.build_configurations.each do |config|
...
config.build_settings['EXCLUDED_ARCHS[sdk=iphonesimulator*]'] = 'arm64'
end
end
end
I haven't done watchOS here because it wasn't a watchOS app, however, we need to do this for all supported simulated device targets.
I left EXCLUDED_ARCHS to arm64 to Any iOS Simulator SDK in the main target for Release mode in the main target. The same logic here applies to other sims.
pod install
Archive again. :D
