ionic serve on iOS 14 device. Error "Invalid Service"

Question

After upgrading an iPhone6s to iOS 14 and Xcode to the latest version, I am unable to serve the app.

The error stack is as following

Error: InvalidService
    at LockdownProtocolReader.parseBody (/usr/local/lib/node_modules/native-run/node_modules/node-ioslib/dist/protocol/lockdown.js:35:19)
    at LockdownProtocolReader.onData (/usr/local/lib/node_modules/native-run/node_modules/node-ioslib/dist/protocol/protocol.js:52:40)

    at TLSSocket.Readable.push (_stream_readable.js:212:10)
    at TLSWrap.onStreamRead (internal/stream_base_commons.js:186:23)

running with --verbose shows the origin of the error

client:lockdownd startService: com.apple.debugserver +898ms
  protocol:lockdown socket write: {"Request":"StartService","Service":"com.apple.debugserver"} +206ms
  protocol:lockdown Response: {"Error":"InvalidService","Request":"StartService","Service":"com.apple.debugserver"} +6ms
  native-run Caught fatal error: Error: InvalidService

my serve script is

ionic cordova run iOS --l --debug --device --address=0.0.0.0 --sourceMap=true

Ionic info:

   native-run (update available: 1.1.0) : 1.0.0

   ios-sim    : 8.0.2
   NodeJS     : v12.18.0 (/usr/local/bin/node)

   OS         : macOS Catalina
   Xcode      : Xcode 12.0 Build version 12A7209

what I have tried so far.

• reboot Mac
• reboot iPhone
• make sure latest iOS/Mac/Xcode version is installed
• clean build

running on emulator is working fine btw. I can also perform ionic build and run via Xcode on the device.

I solved it by updating native-run to 1.2.1 (see https://github.com/ionic-team/native-run/issues/60, support for iOS 14 has been added in 1.2.0 on 2020-09-28):

npm i -g native-run@latest

Try commenting

     if (isLockdownErrorResponse(resp)) {
         throw new Error(resp.Error);
     }

inside the file

/usr/local/lib/node_modules/native-run/node_modules/node-ioslib/dist/lockdown.js

It worked for me

Answer 3

Got the same error while i was using native-run.

So i tried to run it without native-run and used cordova instead with the flag --no-native-run. The command that worked for me:

ionic cordova run ios -l --address=0.0.0.0 --no-native-run
