Until they fix it, here is the workaround that fixed the iOS build

• Update: patches/@Nozbe+watermelondb+0.25.5.patch

Add below lines at the top of the file

• Bitcode is no longer supported in Xcode 16 so we need to stripe it

Update: ios/Podfile
Add below lines inside post_install block

  bitcode_strip_path = `xcrun --find bitcode_strip`.chop!
  def strip_bitcode_from_framework(bitcode_strip_path, framework_relative_path)
    framework_path = File.join(Dir.pwd, framework_relative_path)
    command = "#{bitcode_strip_path} #{framework_path} -r -o #{framework_path}"
    puts "Stripping bitcode: #{command}"
    system(command)
  end
  framework_paths = [
    "Pods/FBAEMKit/XCFrameworks/FBAEMKit.xcframework/ios-arm64/FBAEMKit.framework/FBAEMKit",
    "Pods/FBSDKCoreKit/XCFrameworks/FBSDKCoreKit.xcframework/ios-arm64/FBSDKCoreKit.framework/FBSDKCoreKit",

    "Pods/OpenSSL-Universal/Frameworks/OpenSSL.xcframework/ios-arm64_armv7/OpenSSL.framework/OpenSSL",
  ]
  framework_paths.each do |framework_relative_path|
    strip_bitcode_from_framework(bitcode_strip_path, framework_relative_path)
  end

Note: You can add or remove items in framework_paths as per your usage

• Upgrade

"react-native-image-crop-picker": "RocketChat/react-native-image-crop-picker#..." -> "^0.41.2"

"expo-apple-authentication": "^6.3.0" -> "^6.4.2"

• Run pod install

there will be error about TOCropViewController. Update it with the instruction given in error.

• Update: ios/Shared/Extensions/WatermelonDB+Extensions.swift

Comment everything inside func query<T: Codable>(raw: SQL, _ args: QueryArgs = []) -> [T] {
and add return []

• Update: ios/Shared/RocketChat/Database.swift

Comment everything inside func readRoomEncryptionKey(rid: String) -> String? {
and add return nil

Comment everything inside func readRoomEncrypted(rid: String) -> Bool {
and add return false

• Finally run it

yarn ios

@krishan-kumar-mourya i tried using your script to remove bitcode, but i still get an error? any ideas?

@krishan-kumar-mourya i tried using your script to remove bitcode, but i still get an error? any ideas?

@Alexdc-12 you can try following things:

• You may need to run pod install again after adding the script (add the script at the end)
• Make sure the path you entered for OpenSSL is correct. For me it was at Pods/OpenSSL-Universal/Frameworks/OpenSSL.xcframework/ios-arm64_armv7/OpenSSL.framework/OpenSSL
• make sure there is no error in your pod install command otherwise it may not execute the script to remove bitcode

Thanks! It's was the pod-install part i was missing! Now archives! Thanks!

It's an issue with expo-apple-authentication because iOS 18 added one more error code which needs to be handled by the switch statement.

To resolve this issue please update expo-apple-authentication to latest version or use xcode 15

expo/expo#31555 (comment)

Also i think core team is currently using xcode 15 and they will update the package once they move into xcode 16
