When I integrate a local package in my Xcode project everything is fine initially but when i switch branches and want to run the app Xcode gives me the compile error Missing package product <package name>
. When I quit Xcode and re-open it everything is fine again. Any idea what this can be? An Xcode bug?
We also integrate external packages via Swift Package Manager which works perfectly fine. No issues there.
The issue is also well described in a post by Jesse Squires .
对我来说,我需要 File > Swift Packages > Reset Package Caches
In Xcode go to File > Swift Packages > Update to Latest Package Versions
Worked for me
In Xcode go to Product > Clean Build Folder
This worked for me. The problem originally started when I was trying to solve another issue that came up after I deleted my Derived Data folder.
Restarting Xcode didn't work, but cleaning the build folder did. I don't know if the other answers here would work for me because I didn't try them seeing as cleaning the build folder worked.
I bumped into this issue today on Xcode 13.0 when working on the WooCommerce iOS app after manually deleting the DerivedData
folder.
The build was failing like in the questions description: Missing package product '<package name>'
I tried both resetting the packages cache and updating to the latest versions, but neither work. Thinking about it, that's not surprising since the packages Xcode couldn't find were local packages .
What did the trick for me was following this suggestion from an Apple forums thread and remove the local packages references, then adding them back again.
In WooCommerce's case, the local packages are part of a workspace file. Removing then adding them back again in the same order didn't result in a diff in the file. That is, nothing really changed in the workspace setup, but that was apparently the kind of kick Xcode needed to get over that error. 🤷♂️
None of the answers worked for me on Xcode 12.5 beta. I had to manually remove all spm packages and re add them.
I'm not sure of the root cause, but I get this quite regularly. Not the most elegant solution, but neither Reset Package Caches nor Update to Latest Package Versions worked for me. For me, I had to quit Xcode, and delete DerivedData.
rm -rf ~/Library/Developer/Xcode/DerivedData/*
Then rebuild.
SPM - Reset Package Caches vs Update to Latest Package Versions
File -> Swift Packages -> Reset Package Caches
File -> Swift Packages -> Update to Latest Package Versions
Update to Latest Package Versions
fetch the latest possible version(based on restrictions)
Reset Package Caches
reset cache(derived folder) -> Update to Latest Package Versions
folder
<path_to_derived_data>/<randomizer>/SourcePackages/checkouts/<project_name>
//e.g
/Users/alex/Library/Developer/Xcode/DerivedData/SPM-dpsmlyjrashqjefkfheppizcrgic/SourcePackages/checkouts/SPMExperiments
A workaround for me at the moment has been both running Product > Clean Build Folder (cmd-k) and then restarting Xcode. This is an issue in both Xcode 12.4 and 12.5, and 12.5's per user package caching did not resolve the issue.
File > Swift Packages > Reset Package Caches also appears to work but it is slower for me.
Context:
One of my vendors distributes their pre-compiled binary library via SPM. Whenever I switch between git development branches, I get:
"artifact of binary target 'xyz' failed extraction: The operation couldn't be completed. (TSCBasic.StringError error 1.)"
It also causes these "missing package product" errors for totally unrelated packages presumably because if one package fails the whole SPM process fails ("resolving package graph failed") even if these package are entirely independent.
Edit: With Xcode 12.5 simply quitting Xcode and re-opening seems to be enough.
I got this error when having the same local Swift package open in two different instances of Xcode in two different projects. Got it working again by quitting Xcode and only having one project open at a time.
Xcode Source Control should be enabled to run this. Preference -> Source Control and enable the source control.
Start with the other answers like
If this doesn't help...
In my messages I found a hint that I had a dependency to two different version of the same package.
After fixing this, Reset Package Caches suddenly worked for most of my packages.
I could fix the remaining problems by adding
platforms: [
.iOS(.v13),
],
to the corresponding package. Before that, I had no platforms
statement.
I had some packages that were part of my project but would intermittently fail to build.
I found that specifying the path to the Sources
and Tests
folders resolved the issue:
targets: [
.target(
name: "MyInternalPackage",
dependencies: [],
path: "Sources"), // <<<<<< Even tho this is the default, sometimes get build errors without it
.testTarget(
name: "MyInternalPackageTests",
dependencies: ["MyInternalPackage"],
path: "Tests") // <<<<<< Even tho this is the default, sometimes get build errors without it
]
在项目中的当前分支重命名后我遇到了这个问题,并通过清除工作区中的 xcuserdata 来解决它。
If none of the above answers work, Please refer the solution shared by GravityBytes in this link on Apple Forums.
Eventually he happened to share the below resolution
I eventually got this resolved. What seemed to get it working was re-adding my local packages using the "Add Packages…" menu option on the project that has the framework targets using the local package. This created a new "Packages" group in the project, and eventually started compiling correctly.
Please remove the existing references and try adding them using the above approach.
For Moya I had to edit project file to Xcode heart's content
/* XCRemoteSwiftPackageReference "Moya" */ = {
isa = XCRemoteSwiftPackageReference;
repositoryURL = "https://github.com/Moya/Moya";
requirement = {
kind = upToNextMajorVersion;
minimumVersion = 13.0.2;
};
anything other than 13.0.2 results in unresolutio for the numerous semicircular dependencies that Moya package brings to the table.

除了Product
-> Clean Build Folder
and Restart
对我没有任何帮助
I tried:
And restarting the Mac is what worked
Others say doing "Resolve Package Versions" multiple times also work.
For me, Xcode was opened using Rosetta which wans't enabled before. Re-disable open using Rosetta helped me
In Xcode 12.0.1 (12A7300) this bug has been fixed. It was auto-resolved by the Xcode update for me.
EDIT Xcode 12.5 [beta]
Apple added a SPM cache. See my question here . If you run into this problem with this Xcode version it might help to delete this cache.
