Xcode Swift Editor placeholder in source file Compile Error - CAPBridge.swift

Capacitor
1

I am creating an app with Ionic/Angular/Capacitor. My app has been compiling and building fine for while. I was able to build and run the app on the Xcode simulation as well as my iPhone. However, I had a recent pop up for an Xcode update that I subconsciously click OK on without paying much attention about it. What a stupid thing to do!!! Now, I am getting a Capacitor Buildtime error of "Swift Compiler Error - Editor placeholder in source file - CAPBridge.swift in this area of the code:

 public func modulePrint(_ plugin: CAPPlugin, _ items: Any...) {
    let output = items.map { "\($0)" }.joined(separator: " ")
    CAPLog.print("⚡️ ", plugin.pluginId ?? <#default value#>, "-", output)
  }

The Swift Compiler replaced the “<#default value#>” part of the code with the gray box with “default value” in it with the error message “Editor placeholder in source file”. I confirmed that the CAPBridge.swift file came from my nodes_modules/@capacitor/ios/Capacitor/Capacitor folder.

I am not a Swift programmer and was not able to find anything that would tell me why this error comes up now, or a way to fix it. Could someone please help?

The following is output from ionic info:Ionic:

I’ve posted this same question on Stack Overflow and got an answer from @jcesarmobile

uninstall @capacitor/ios
npm install @capacitor/ios
npx cap sync ios

This worked and fixed the compiler error. My app is working again. Thanks!
