Comparing two strings in Swift is straightforward and can be done using the equality operator ==. This operator checks if two strings are exactly the same in terms of their characters and the order in which these characters appear.
In Swift, there are several ways to check for nil and assign a value to a variable, depending on the context and what you want to achieve. Here are some common approaches:
The below should work both on macOS and iOS with one minor change. That is, use UIColor instead of NSColor if you’re planning to use it for iOS.
For various reasons you may want to convert the Color type to a String. And, below is a relatively cleaner way to do it.
In Swift, the switch statement doesn’t automatically fall through to the next case. Each case block is designed to execute only the code within that case, and it doesn’t continue to the next case unless you use the fallthrough keyword.
In Swift, if you encounter a “Result of call to ‘function’ is unused” warning, it means that you’re calling a function that returns a value (typically a result type, such as Result or any other type), but you’re not doing anything with the result. To get rid of this warning, you have a few options depending on the specific situation:
In macOS 14.0 (Sonoma), Apple removed support for NSApp.sendAction to open the Settings view in your SwiftUI app. You now have to use SettingsLink like below:
You can ignore mouse events in a window/view by adding just a single line of code.
If you go to Xcode > File > Swift Packages, you can see options to add a new Swift package, update them, reset caches, and resolve package versions. However, you do not see an option to remove a particular Swift package.
You can open your app’s window on top of all other open application windows with the below code:
Before launching the window, just use the appropriate window level, and you’re done.
Adding Global Keyboard Shortcuts to your macOS app can be a pain as there isn’t a Cocoa API for the same. You would have to rely on the old, most of which are deprecated, Carbon API.
