Xcode 11 Build System Bugged?

I am using Xcode 11 GM with macOS Mojave 10.14.6. I have been experiencing problems with my app's build. What I mean is that the first time I compile an app on my iPhone, its okay but then if I make changes to the code and compile again: it doesn't show those changes. But when I do it on the simulator the changes do show. In order to see the changes on my phone, I have to uninstall and reinstall the app. I have also been looking for known issues on apple's website: Known Bugs.

But I cannot seem to find a specific bug for what I am experiencing? My iPhone is the XR model version 13.1.2. Thank you.

Solution

  • I had the same issue and what did it for me was to chose the Legacy build system instead of the New build system in the Workspace settings:

    1. Click on "File" in Xcode top menu
    2. Click on "Workspace settings"
    3. Chose the Legacy build system for the Build system setting

    I hope it helps
