We finally got a declarative UI framework (SwiftUI) after struggling through the awful experience of Interface Builder for so many years, but even with a fresh start like that the Xcode team still just can't deliver a tolerable development experience. Just Xcode things.įor every small step forward, there are a hundred steps backward. When it happened the first time, I wasn't even a little surprised. It's essential to learn the "toggle canvas" and "refresh canvas" keyboard shortcuts when building with SwiftUI or you will spend inordinate amounts of time clicking buttons just to get the "live previews" to actually update.Īnd, lastly - this isn't a joke - sometimes the IDE's controls / labels are rendered upside down, so you have to learn to read upside down. SwiftUI previews routinely fail to update. Syntax highlighting and autocompletion frequently break.ĭerived Data folder regularly needs to be cleared (which incidentally instigates a package restore again). SPM cache constantly needs to be cleared and packages restored. ![]() Some features may require Internet access. To submit your apps to the App Store you must be a member of the Apple Developer Program. To test or run applications on an iPhone, iPad, Apple TV, or Apple Watch all you need is a free Apple ID. Create custom instruments with unique visualizations to analyze your own code and frameworks.Analyze your app directly, or sample the entire system with very little overhead.Identify performance bottlenecks, then dive deep into the code to uncover the cause.Compare CPU, disk, memory, and GPU performance as graphical tracks over time.Data tips and Quick Look can inspect a variable by hovering your mouse over code while debugging.Open Quickly instantly opens any file within your project.Refactoring makes it easy to modify the structure of Swift, Objective-C, C, and C++ code.Professional editor and debugger keep your code front and center ![]()
