consider supporting xcframworks

[johndpope]

had some success spitting this out

https://github.com/mstfy/spm-to-xcframework

/Users/johndpope/Desktop/spm-to-xcframework/.build/arm64-apple-macosx/release/spm-to-xcframework Sup
abase --path /Users/johndpope/Desktop/supabase-swift --output /Users/johndpope/Desktop/xcframework

it's helpful for bazel builds

[johndpope]

Sorry - bumping into several issues here

this library
https://github.com/unsignedapps/swift-create-xcframework

brew install mint
mint install unsignedapps/swift-create-xcframework
swift create-xcframework --platform ios

I need a path to get this working -
the realtime has an issue with zlib

spleeter) ➜ supabase-swift git:(master) ✗ swift create-xcframework --platform ios
Error: Xcode project generation is not supported by Swift Package Manager for packages that reference system modules.These system modules were referenced: swift-nio-zlib-support

        .product(name: "PostgREST", package: "postgrest-swift"),
      ]
    )
  ]
)

I still hit this

I hack the package to use my fork which has this fix
daltoniam/Starscream#844

but still not working...

swift create-xcframework --platform ios --stack-evolution

let closeCode = (error as? WSError)?.code ?? RealtimeClient.CloseCode.abnormal.rawValue

probably due to the hot fix above - I'll do some digging.

UPDATE

after some hotfixes - I got it to compile.

not sure what's going on - but seems like theres some code rot with the realtime.

        .product(name: "PostgREST", package: "postgrest-swift"),
      ]
    )
  ]
)

not sure if this will work - but goal is to get a file like this
https://github.com/wweevv-johndpope/supabase-xcframework

UPDATE
so it's possible to render out all the frameworks as so

swift create-xcframework AnyCodable ComposableKeychain Get GoTrue KeychainAccess PostgREST Realtime Starscream SupabaseStorage URLQueryEncoder XCTestDynamicOverlay --platform ios --stack-evolution

something breaks on import

[johndpope]

https://github.com/apple/swift-package-manager/blob/main/Sources/SPMLLBuild/llbuild.swift

It maybe possible to reduce number of xcframeworks by using this technique
https://developer.apple.com/forums/thread/650995
You’d just need to modify a couple of lines in this library…. (I think)

UPDATE -

at this point using a bunch of hot fixes (renamed modules) + swift-create-xcframework

I can successfully create all the packages -

// swift-tools-version:5.5
// The swift-tools-version declares the minimum version of Swift required to build this package.

import PackageDescription

let package = Package(
  name: "Supabase",
  platforms: [
    .iOS(.v13),
    .macCatalyst(.v13),
    .macOS(.v10_15),
    .watchOS(.v6),
    .tvOS(.v13),
  ],
  products: [
    .library(
      name: "Supabase",
      targets: ["Supabase"]
    )
  ],
  dependencies: [
    .package(url: "https://github.com/wweevv-johndpope/gotrue-swift", from: "0.0.10"),
    .package(url: "https://github.com/supabase-community/storage-swift.git", from: "0.0.2"),
    .package(url: "https://github.com/wweevv-johndpope/realtime-swift.git", from: "0.0.5"),
    .package(url: "https://github.com/supabase-community/postgrest-swift", from: "0.0.6"),
  ],
  targets: [
    .target(
      name: "Supabase",
      dependencies: [
        .product(name: "GoTrue", package: "gotrue-swift"),
        .product(name: "SupabaseStorage", package: "storage-swift"),
        .product(name: "Realtime", package: "realtime-swift"),
        .product(name: "PostgREST", package: "postgrest-swift"),
      ]
    )
  ]
)

So currently - this is crashing
binaryscraping/swift-composable-keychain#1

UPDATE

this is a slim example of supabase integration + bazel - demonstrating crash.

git clone https://github.com/wweevv-johndpope/DemoBazel/tree/supabase
./xcodegen app

Supporting xcframework is not in the roadmap for now, we can revisit this later if priority changes.

Hi @bok- have you encountered any problems in general with xcframework / where the swift code that would automatically deallocate / BAD_EXEC - but run fine when code is ran locally?
