Fixing the SQLite.swift Simulator Issue on M1 Chip: A Clear Guide

If you've recently upgraded to a MacBook Pro with an M1 chip and are using SQLite.swift for your iOS project, you might have run into a frustrating issue while trying to run your application in the simulator. Specifically, you may have encountered the error message:

[[See Video to Reveal this Text or Code Snippet]]

In this guide, we’ll explore what this error means and provide detailed instructions on how to resolve it without resorting to hacks like running Xcode via Rosetta.

Understanding the Problem

The root of the problem lies in the architecture incompatibility:

Your project is trying to build for x86_64, which is typical for older Intel-based Macs.

However, SQLite.swift is correctly building for arm64, which is the architecture used by M1 chips.

As a result, when you attempt to run your project in the simulator, the build fails due to this inconsistency.

Why Running Under Rosetta Is Not Ideal

While one workaround is to start Xcode using Rosetta, doing so translates your code for the Intel architecture. This method comes with trade-offs, including:

Increased memory usage

Lower performance

Ultimately, it’s not the best solution for development, particularly if you can easily fix the underlying issue.

Step-by-Step Solution

Here's how you can resolve the problem by properly configuring your build settings without impacting your project's performance:

1. Check Build Settings

Ensure your project settings are appropriate for the M1 architecture:

ARCHS: This setting defines the architectures your project builds for. Ensure that you don’t modify it unnecessarily.

SUPPORTED_ARCHS: Similar to ARCHS, this should remain unchanged unless updates are required for specific dependencies.

2. Manage Excluded Architectures

EXCLUDED_ARCHS: This setting can force your project to build for a certain architecture. Unless you are directly using a binary dependency that hasn’t been updated to support arm64 for the simulator, avoid setting this option. If you previously adjusted this setting out of caution, it might cause more issues than it solves.

3. Let Xcode Manage Architectures

By default, Xcode is set up to build for the simulator using your Mac's native architecture. In debug builds, it typically compiles for a single architecture, accordingly, while in release builds, it compiles for all supported architectures.

4. Review Dependencies

If you still encounter issues, examine your project’s dependencies. Some may not yet support the M1 chip:

If you are using CocoaPods to install SQLite.swift, verify that all dependencies are updated to their latest versions that support arm64.

Consider switching to Swift Package Manager (SPM) if you haven’t already, as it could handle some dependencies more effectively.

Conclusion

By following these steps, you can ensure that your project is configured correctly for the M1 chip, allowing SQLite.swift to run smoothly in the simulator.

Important Notes:

Always keep your Xcode and the associated packages up to date to minimize compatibility issues.

Regularly consult the documentation for SQLite.swift and other dependencies for known issues relating to new developments in Apple silicon.

With these adjustments, you should be able to enjoy a smooth development experience on your MacBook Pro with the M1 chip, free from unnecessary hacks and performance penalties.
