I'm having this problem in 2025! Once every 20-30 runs, my app will fail to get an item from the keychain at launchtime or in the background. The error returned is -25300. I am going to switch to use UserDefaults instead, but I was curious to see if this issue had been fixed, or if there is usage or workarounds.

Here's how to fix this: docker run \ --rm \ --volume "$(pwd)/:/src" \ --workdir "/src/" \ swift:5.3.1-amazonlinux2 \ /bin/bash -c "yum install -y libcurl-devel && \ swift build --product HelloWorld -c release -Xswiftc -static-stdlib" This will install what is needed for the linking to succeed.
