I am creating an app with Ionic/Angular/Capacitor. My app has been compiling and building fine for a 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 what I did. 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)
  }

On the Xcode editor, the "<#default value#>” part of the code was replaced with a gray box and the “default value” text in it with the error message “Editor placeholder in source file”. I am not a Swift programmer and was not able to find any reason why this error would comes up now, or a way to fix it. I’ve posted the same question on the Capacitor Forum. However, I am hoping that someone would recognize the "<#default value#> syntax or know of any recent changes in Xcode that would cause such error.

There is one more observation. To make sure, I did a Clean before trying to run the app on the Xcode simulator again. When I do a Product -> Clean Build Folder, I got a different Swift Compiler Error after the Clean finished. I got "No such module ‘Cordova’" in CAPBridge.swift. This error will go away and be replaced by the "Editor placeholder in source file" error. BTW, I am using Capacitor and not Cordova and have never done a Clean in the past while things were all running fine. So, I am not sure if the "No such module ‘Cordova’" error has always been there from a Clean operation.

The following is the output from running ionic info to show my current running environment:

  1. You can resolve the compiler error by replacing <#default value#> with "n/a".

  2. Uninstall @capacitor/ios and reinstall it to get the original code, then run sync

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