Package resolution is suddenly failing in Xcode. I tried the following options:
File/Packages/Reset Package Caches
rm -Rf ~/Library/Caches/org.swift.swiftpm/
I can see following error for different packages.
You're using an RSA key with SHA-1, which is no longer allowed. Please use newer client or a different key type.
After looking around, I found out Github security blog that mentions that from 15th March 2022 onwards, RSA keys with SHA-1
are no longer accepted. See blog here
I tried creating SSH key with command provided on Github documentation but it turned out that Xcode does not accept ED25519
encryption method and commands provided at Github docs do not work.
Eventually I found this nice post the explains the issue and offers alternative encryption method ECDSA
that is accepted by Xcode.
Use the following command to create new SSH key and add it to Github.
ssh-keygen -t ecdsa -b 521 -C "your_email@example.com"
