Managing iOS Simulators

List all simulators created

$ xcrun simctl list --json

Delete old and unavailable simulators

$ xcrun simctl delete unavailable

Problem

You have installed GPG, then tried to perform a git commit and suddenly you see this error message after it 😰

error: gpg failed to sign the data
fatal: failed to write commit object

Understand the error (important to solve it later!)

You can do a lot of fun stuff to collection views. I like to subclass UICollectionViewFlowLayout. Here is an example that fades the top and the bottom of the collection view based on distance from center. I could modify it to fade only the very edges but you should figure it after you look through the code.

import UIKit

class FadingLayout: UICollectionViewFlowLayout,UICollectionViewDelegateFlowLayout {

    //should be 0<fade<1

iOS Cell Registration & Reusing with Swift Protocol Extensions and Generics

A common task when developing iOS apps is to register custom cell subclasses for both UITableView and UICollectionView. Well, that is if you don’t use Storyboards, of course.

Both UITableView and UICollectionView offer a similar API to register custom cell classes:

public func registerClass(cellClass: AnyClass?, forCellWithReuseIdentifier identifier: String)
public func registerNib(nib: UINib?, forCellWithReuseIdentifier identifier: String)

	import CoreGraphics
	import Accelerate
	import CoreImage
	import UIKit

	extension CGImage {

	public enum Error: Swift.Error {
	case imageResizingFailed
	case cgContextCreationFailed

	#!/usr/bin/env bash

	function link_stree {
	ln -s /Applications/SourceTree.app/Contents/Resources/stree /usr/local/bin/
	}

	function install {
	link_stree
	}

	## Open GitKraken using the current repo directory.
	## For when you want a prettier view of your current repo,
	## but prefer staying in the cli for most things.
	## This will break if GitKraken ever removes the -p flag.
	## If you're not using OSX, the path is definitely different.

	kraken () {
	~/Applications/GitKraken.app/Contents/MacOS/GitKraken -p $(pwd)
	}
