tylermilner / copy_appropriate_google-service-info-plist.sh
Last active January 25, 2024 10:52
A shell script to selectively copy your GoogleService-Info.plist into your app bundle based on the current build configuration.
# Name of the resource we're selectively copying
GOOGLESERVICE_INFO_PLIST=GoogleService-Info.plist
# Get references to dev and prod versions of the GoogleService-Info.plist
# NOTE: These should only live on the file system and should NOT be part of the target (since we'll be adding them to the target manually)
GOOGLESERVICE_INFO_DEV=${PROJECT_DIR}/${TARGET_NAME}/Firebase/Dev/${GOOGLESERVICE_INFO_PLIST}
GOOGLESERVICE_INFO_PROD=${PROJECT_DIR}/${TARGET_NAME}/Firebase/Prod/${GOOGLESERVICE_INFO_PLIST}
# Make sure the dev version of GoogleService-Info.plist exists
echo "Looking for ${GOOGLESERVICE_INFO_PLIST} in ${GOOGLESERVICE_INFO_DEV}"

tylermilner / Xcode Breakpoints.swift
Last active August 24, 2023 17:08
These are Xcode breakpoints I've found to be very useful to have turned on to help debug iOS applications and spot problems early. After creating each one, right-click on it and click "Move Breakpoint To" -> "User" so that the breakpoint will automatically be active for any Xcode project you open.
All Objective-C Exceptions
// Catches exceptions thrown by Objective-C code.
// Default Xcode breakpoint created by clicking "+" to add breakpoint -> "Exception Breakpoint".
// Change "Exception: All" to "Exception: Objective-C".
-[UIApplication main]
// Helps when printing objects via the debugger by making it aware of the classes in UIKit.
// Symbolic breakpoint created by clicking "+" to add breakpoint -> "Symbolic Breakpoint".
// Enter "-[UIApplication main]" for the Symbol.
// Choose Action -> "Debugger Command".

tylermilner / Slow_Compiling_Swift_Code.swift
Created November 27, 2017 22:55
Code samples of common sources of slowdowns for the Swift 2/3 compiler.
//
// The code snippets below showcase common "problem code" that can take a long time to compile.
// These examples were primarily observed in Swift 2/3 and may no longer be relevant in Swift 4 or higher.
//
/// 1. Array concatenation
// Observed by Robert Gummesson - https://medium.com/@RobertGummesson/regarding-swift-build-time-optimizations-fc92cdd91e31#c75c
// Joining two arrays together with the '+' operator can be expensive to compile.
let someArray = ["a", "b"] + ["c", "d"]

tylermilner / averageBuildTime.sh
Created May 1, 2020 15:34
A simple Bash script to generate an average build time for your iOS project. Replace with your project's workspace and scheme before use.
#!/bin/bash
# Workspace and scheme parameters for the project
workspace="ProjectWorkspace.xcworkspace" # TODO: Replace with your project's workspace
scheme="ProjectScheme" # TODO: Replace with your project's scheme
# The number of times to build the project
numRuns=3
# Abort the process if any of the commands in this script fail

tylermilner / Cupcakes_MapAndFlatMap.swift
Last active July 10, 2019 20:59
A Swift playground showcasing some use cases for map and flatMap using Cupcakes.
import UIKit
/// Introduction
// This playground showcases many potential use cases of `map` and `flatMap` in Swift (beyond transforming collections).
// See this article on Medium for more information: https://medium.com/rocket-fuel/step-up-your-functional-game-map-and-flatmap-tricks-cdc1578fe7bc
// To run this playground in Xcode, copy/paste the contents of this file into a new playground (playgrounds are technically directories so GitHub Gist doesn't work well with them).
// There are several comment blocks that represent the "old way" of doing things (without `map`/`flatMap`). Feel free to uncomment these to verify functionality.
#
#### DEPRECATED ####
# Use the standard .swiftlint.yml for all files in your project, including tests.
