Swiftgen: Homebrew on ARM (Apple Silicon) support

[bdolewski]

Hi everyone! I know it's mostly Homebrew issue but I was curious if this is 100% Homebrew problem or something can be done in SwiftGen (already posted in Homebrew's issues list about that one).

I installed the swiftgen via homebrew like this:

brew install --build-from-source swiftgen

Got following errors at the end of the build (see full output: https://gist.github.com/bdolewski/53359ba6379c7c8834939265bd9e7e8b)

SwiftGen is installed but when I try to run it it's killed by macOS (I guess is something related to signing code of Kanna, PathKit and Stencil frameworks.

Afaik homebrew does not support ARM yet. You can work around it by prefacing any brew command with this:

arch -x86_64 brew ...

For more info read this article: https://soffes.blog/homebrew-on-apple-silicon

From other issues/comments here, I'm pretty sure SwiftGen works on ARM when installed via Mint (https://github.com/yonaskolb/Mint).

Hi @djbe
That's correct - Homebrew does not support Apple Silicon yet. That's why I wanted to check things out as an early adopter 😉

I downloaded zip file from stable branch. I run build script using command bundle exec rake cli:install.
Got following build log (the last part is similar to the output from Homebrew):

SwiftGen-stable bundle exec rake cli:install

[bdolewski]

However I opened SwiftGen.xcworkspace in Xcode 12.3 and build & run SwiftGen without any issues.

[djbe]

Hmmm curious, I wonder if there's a difference between the 2. Will have to investigate.

Probably refs #805.

[bdolewski]

To me looks like some difference between build configs/setups. Seems like Xcode 12.3 can handle it but commands produced by rake does something different with signing the code that used to work on Intel CPU's (I assume rake runs on Intel without any warnings. I don't believe that signing issues are only present on arm64 but not on x86 - I guess it would fail the same way).
Maybe some commands are out of order for Apple Silicon. Is there something I can try/test to help you out?

codesign is failing on permission issue ( understandable as the files are not writable.)
Can someone explain me why file permission is set to -w before applying signature?

[mudithsilva]

I checked in Mint installation and it's working fine on Apple Silicon.
Try :-

To install Mint:- brew install mint
To Install SwiftLint:- sudo mint install realm/SwiftLint
To Install SwiftGen:- sudo mint install SwiftGen/SwiftGen
To manually run the SwiftLint and SwiftGen (navigate to project folder) :- mint run swiftgen and mint run swiftlint

Closing this as a duplicate of #805. Hope to create a release in the coming week.
