My project was created on a Mac with an Intel processor. Predictive code completion is enabled in Safari settings. The predictive model is loaded. However, the predictive typing does not work. For new projects it works. I took the following steps to fix this problem:
1. Ensure Indexing is Enabled and Up-to-Date:
Enable Indexing:
In Terminal, run the command defaults write com.apple.dt.XCode IDEIndexDisable 0.
Clean and Rebuild:
Go to "Product" > "Clean Build Folder" in Xcode. Then, rebuild your project.
Check Derived Data:
Xcode uses a "DerivedData" folder to store build artifacts. Try clearing this folder by navigating to ~/Library/Developer/Xcode/DerivedData and deleting its contents (you can use the command rm -rfv * in Terminal).
2. Verify Xcode Settings:
Enable Predictive Code Completion:
Go to Xcode > Settings > Text Editing > Editing and ensure "Predictive code completion" is checked.
Check for Predictive Code Completion Model:
In Xcode, go to Settings > Components. Ensure the "Predictive Code Completion Model" is downloaded and installed. If it's not, try downloading it by clicking the "+" button and selecting it.
Disable and Re-enable:
Try disabling predictive code completion in Xcode's settings and then re-enabling it.
But this not help. I use latest macOS and Xcode.
