10 iOS Development Tips for Swift and Xcode

If you want to become a top-notch iOS developer, these tips will help you save time and resources so you can focus on the parts of code that really matter.

First, Swift has a native function for checking if all elements satisfy a condition: the allSatisfy() function. This function takes a closure as an argument that applies a condition check for each element in the collection.

Second, you can use the where keyword to chain the if-check into the for loop declaration.

Third, you can use tuple destructuring to pull apart values from a tuple into separate variables.

Fourth, you can use Xcode’s built-in refactoring tool to avoid repetitive manual work.

Fifth, you can add multiple cursors into your Swift code using Xcode’s multi-cursor feature.

Sixth, you can extract longer pieces of code into separate methods using Xcode’s built-in refactoring feature.

Seventh, you can extract an expression into a variable using the built-in extract to variable feature in Xcode.

Eighth, you can use Xcode’s built-in refactoring tool to expand the missing cases in a switch statement.

Ninth, you can use a linter like SwiftLint to enforce a common coding style and best practices.

Tenth, you can use tuple destructuring to swap two variables without a third one.
