Xcode line duplication (without overwriting your clipboard)

I find this shortcut extremely useful in Xcode: duplicate one or several lines without losing what you have on the clipboard.

UPDATE: it seems Xcode finally added this feature as of version 14: one can now select text and use the usual duplicate shortcut (Cmd-D)

Bind keys to duplicate lines in Xcode

To add custom key bindings in Xcode, you have to edit this file (su privileges required): '/Applications/Xcode.app/Contents/Frameworks/IDEKit.framework/Versions/Current/Resources/IDETextKeyBindingSet.plist

UICollectionViewDiffableDataSource does an excellent job of handling changes to data and updating the items accordingly. However, there seems to be no good way to handle updates to existing items. If you follow the samples that Apple provides and define Equatable and Hashable to use an id instead of the complete models value, value changes won't cause the collection view to update those cells. If you leave Equatable as it should be and have it compare all values of a model, the cell will update, but it will completely replace the old cell, causing an undesirable "flash".

UICollectionViewComparableDataSource wraps a UICollectionViewDiffableDataSource and will check for items that have been updated, but not removed or added.

This allows us to make updates to a cell without completely reloading it. This is especially usefull if your cells have some sort of temporary state.

This is just an expirement. Use at your own risk.

.env files can be an easy way to setup Environment variables locally. You can start using a .env files in Vapor 3 by following this small guide.

First setup the vapor-ext package in your Package.swift file:

.package(url: "https://github.com/vapor-community/vapor-ext.git", from: "0.1.0"),

Next create a .env file in the root of your project:

Methods of Signing Git Commits on MacOS

Last updated March 13, 2024

This Gist explains how to sign commits using gpg in a step-by-step fashion. Previously, krypt.co was heavily mentioned, but I've only recently learned they were acquired by Akamai and no longer update their previous free products. Those mentions have been removed.

Additionally, 1Password now supports signing Git commits with SSH keys and makes it pretty easy-plus you can easily configure Git Tower to use it for both signing and ssh.

For using a GUI-based GIT tool such as Tower or Github Desktop, follow the steps here for signing your commits with GPG.

	func fetchChildren<Parent, ParentID, Child: Model, Result>(

	combining: @escaping (Parent, [Child]) -> Result) -> Future<[Result]> where ParentID: Hashable & Encodable {
	let parentIDs = parents.compactMap { $0[keyPath: idKey] }
	let children = Child.query(on: conn)

	// triggered when FairPlay handling is required.

	// Load the asset in the player.
