How to do CPU profiling an Ionic iOS app using Safari on a Mac machine?

To do CPU profiling of an Ionic app using Safari on a Mac machine, you can follow these steps:

  1. Connect your iOS device to your Mac machine and open Safari.
  2. In Safari, go to the "Develop" menu and select your connected iOS device.
  3. Open your Ionic app on the device.
  4. In Safari, go to the "Develop" menu and select "Start Remote Debugging" to start the debugging session.
  5. In the Safari developer tools, go to the "Timelines" tab and select "CPU" from the sidebar.
  6. Click the "Record" button to start recording the CPU usage.
  7. Use the app and perform the actions you want to profile.
  8. Click the "Stop" button to stop recording.
  9. Analyze the recorded data to identify any performance bottlenecks.

It will not be possible to do remote debugging and CPU profiling of an iOS app that is not signed with a valid provisioning profile and code signing identity. This requires that the app is built and deployed using a development or distribution certificate from an Apple Developer account, which allows the app to run on a physical device and be debugged remotely. If the app is not properly signed, it cannot be installed or debugged on a physical device using Safari or any other tool.

  7. Under "App Services," select the appropriate services that your app needs, such as Push Notifications or In-App Purchases.
  8. Click "Continue" and review the details of your App ID.
  9. Click "Submit" to register the App ID.

Once your App ID is registered, you can use it to create and manage certificates, provisioning profiles, and other resources that are required to build and distribute your iOS app. Note that you'll need a paid Apple Developer account to register an App ID and distribute your app on the App Store.
