Firebase Environments

Last updated: October 21st, 2019.

At the time of writing this gist (January 4th, 2017), I was unable to find true sandboxing to separate development and production environments for a Firebase project. The closest we can get is to create two separate Firebase projects -- one for development and one for production.

Pros

• Complete separation and isolation of all Firebase features.
• Freedom to experiment without risking the corruption of production data.

Cons

    var blockOperations: [BlockOperation] = []

    var fetchedResultController: NSFetchedResultsController<Entity> {
        if _fetchedResultsController != nil {
            return _fetchedResultsController!
        }
        
        let fetchRequest: NSFetchRequest<Entity> = Entity.fetchRequest()
        let managedObjectContext = (UIApplication.shared.delegate as! AppDelegate).managedObjectContext!

extension UIImage {
    
    // colorize image with given tint color
    // this is similar to Photoshop's "Color" layer blend mode
    // this is perfect for non-greyscale source images, and images that have both highlights and shadows that should be preserved
    // white will stay white and black will stay black as the lightness of the image is preserved
    func tint(tintColor: UIColor) -> UIImage {

# The trick is to link the DeviceSupport folder from the beta to the stable version.
# sudo needed if you run the Mac App Store version. Always download the dmg instead... you'll thank me later :)

# Support iOS 15 devices (Xcode 13.0) with Xcode 12.5:
sudo ln -s /Applications/Xcode-beta.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport/15.0 /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport

# Then restart Xcode and reconnect your devices. You will need to do that for every beta of future iOS versions

# (A similar approach works for older versions too, just change the version number after DeviceSupport)

First, check your current config (example output in homebrew.mxcl.postgresql.plist.xml lower down in this gist):

cat ~/Library/LaunchAgents/homebrew.mxcl.postgresql.plist

Most importantly, note the -D /usr/local/var/postgres argument.

Second, shut down your current PostgreSQL.

launchctl unload ~/Library/LaunchAgents/homebrew.mxcl.postgresql.plist
