Enable this in general settings of Xcode if you're frustrated with not seeing all the errors after a build in latest xcode. With this more will show in one go after a single build instead of one by one after multiple builds.

Found a neat GQL trick to conditionally include some field in your query with @include(if: $shouldIncludeProperty) directive.

iOS/Swift coding tip: use xcrun simctl openurl booted "https://your-deep-link" to open a given link in your currently running simulator. It will either trigger deep linking into your app or open safari.

iOS/Swift coding tip: in your mocks add properties methodNameCallCount and methodNameHandler for each function in protocol you're mocking. This allows you to stub values in tests and assert how many times a method was called.

iOS/Swift coding tip: make properties and methods private by default. This will force you to think about what your actual public/internal interface looks like facilitating good design and architecture practices such as extracting interfaces.

iOS/Swift coding tip: use dependency injection instead of singletons. This will improve your design, testability, and decouple from concrete implementations. One instance has the same result as singleton.

iOS/Swift coding tip: Use sudo xcode-select -switch /path/to/xcode/Xcode-beta.app to select beta version of Xcode as your main version to be able to play with all the new stuff like #SwiftUI and #combine announced at #wwdc last week.

iOS/Swift coding tip: use CFAbsoluteTimeGetCurrent to calculate how long does it take for a line of code to execute. In general you should apple's instruments tool for this but CFAbsoluteTimeGetCurrent is handy for quick checkup

iOS/Swift coding tip: use https://t.co/9R3VwXBvZI to generate codable structs out of a JSON file. It will create types and link them with CodingKeys enums. It's handy if you need to generate a lot of models passed from the backend.

iOS/Swift coding tip: use "xc" bash command to open Xcode project in your current folder https://t.co/gJN9sQ1AwA
It goes through your folder and finds xcworkspace or xcodeproj to open. I've been using it for years and originally got it from @subdigital

iOS/Swift coding tip: use typealias to name networking request callback closures. It is more explicit and correct to give your callbacks a name. Naming them is the first step to eventually extracting an enum or other type if they get complex.

iOS/Swift coding tip: use @CocoaPods as your preferred dependency management tool. It does a better job than Carthage or Swift Package Manager and is a gateway to using other helpful #ruby tools in your project such as @FastlaneTools.

iOS/Swift coding tip: use UITableViewCell extension helper that declares static identifier function to be used for registering and dequeueing cells. NSStringFromClass(self) will help you avoid typos and declaring static string for each cell.

iOS/Swift coding tip: Xcode has a powerful pattern search. Access it by pressing crl + alt + cmd + P in Find In Workspace field. You could add Any character or word pattern and mix and match multiple. Handy if you stick with name conventions.

iOS/Swift coding tip: use SnapKit (https://t.co/e4vPoETgYz) over Apple autolayout API and programmatic autolayout over storyboards/xibs.
Programmatic autolayouts are more expressive and let you scale to bigger teams. PRs show clear diff too.

iOS/Swift coding tip: I highly recommend using an xcode code snippet like this one to create private let properties. Have it be bound to `plet` completion shortcut. This will help and encourage you to set your properties as private by default
#ios #swift #swiftlang #ioscodingtips
iOS/Swift coding tip: use higher level of abstraction for async work such as RxSwift, ReactiveCocoa, PromiseKit, NSOperation rather than GCD functions. Grand Central Dispatch is what powers all of them but in most cases it's too low level.

iOS/Swift coding tip: use very helpful https://t.co/Da50NPXDce to quickly test different formats for your dates. (I don't know how about you but I can never remember how to do it correctly).
Thank you @subdigital for creating it!

iOS/Swift coding tip: use private static properties when you need to share something internally across instances of a type. Only use it for things that don't need to be injected, such as a formatter that's expensive to create in a viewmodel.
